Bats

What size Bat should I use?

We recommend starting with a length based on a player's height and weight as seen below. These charts simply serve as a starting point. As far as the best weight, it will vary from player to player depending on one's personal preference, age, hitting style, bat speed, and strength. Typically we recommend the longest and heaviest bat that you can swing without losing bat speed or affecting your swing. The FEEL of the bat will be the most important factor. You have to make sure it feels right to you. The more you like it the more confident you will be at the plate! 

HELP DECIDING BETWEEN TWO SIZES

  • Longer/Heavier Bat: Will be better for players that are growing but can cause a dip in their swing. Also it moves the sweetspot of the bat further away from the player which can cause more miss hits. For a growing or younger player that can handle the heavier bat without issue compared to the lighter, it is best to go with the longer/heavier bat.
  • Shorter/Lighter Bat: Will give far more control of the bat, and keep the sweetspot closer to the player. They can always adjust in batter's box. The down side for growing players is you might have to buy more bats over time. Tony Gwynn, one of the greatest batters in MLB history and a grown man who weighed well over 200lbs, used a 32 ½ inch bat the majority of his career. It is not always better to just keep sizing up.

IMPORTANT BASEBALL BAT RULES

Baseball unlike Fastpitch Softball has certain Drop (Length-to-Weight Ratio) requirements per age group. It is important to keep track of these as there is a certain point over 4 years where you have to have a different drop each year. If you can swing the heavier earlier without hurting your swing it can be beneficial.

  • 12 & Under (12u): Any Drop
  • 13 & Under (13u): Must be a DROP 8 or Heavier
  • 14 & Under (14u): Must be a DROP 5 or Heavier
    • NEW for 2026: USSSA and Perfect Game have opted for 14u to swing BBCOR (Drop 3) bats. Some states can opt to allow Drop 5's so check with your tournament directors to see what you can swing. 
  • 15 & Under (15u): Must be a BBCOR (Drop 3)
  • High School (Regardless of Age): Must be a BBCOR (Drop 3)

LENGTH-to-WEIGHT RATIO

The ''DROP'' as some may call it, or the number with the MINUS in front of it is the LENGTH-to-WEIGHT ratio. This defines the difference between the length of the bat in inches and the weight of the bat in ounces. The larger the number, the lighter the bat.

Bat Care & Break In

The following are tips and tricks to take care of your bat and make sure that you properly break it in for maximum performance. At the end of this post there are some illegal break in procedures that you should absolutely avoid. Some stores and websites offer to roll or shave a bat. We do not recommend this as both are illegal and can result in multiple issues for you.

BAT CARE

  • Rotate your bat 1/4 turn each swing to distribute the hitting surface evenly
  • Limit the bat to individual use.
  • Do not use in temperatures below 50 degrees Fahrenheit.
  • Do not store the bat in extremely hot or cold temperature areas. It takes about 4 hours for a bat to reach the temperature that it is in. You can use the bats in colder weather as long as they are stored in warm places.
  • Do not use the bat to hit the dirt off of your metal cleats
  • Use regulation leather covered baseballs and softballs. Avoid the dimpled cage balls. It's best to keep an old bat, wood or a cheaper alloy for practice.
  • Do not hit waterlogged balls
  • Routinely check your bat for any damage

BREAK IN

  • Aluminum / Alloy bats do not require a break-in period. These bats are ''hot out of the wrapper'' and can be used in a game right away.
  • Composite bats may require a break-in period. If you feel your bat is not at optimal performance out of the wrapper, we recommend about 50-100 swings either off of a tee or by soft toss with a 1/4 rotation of the barrel after each swing. Some bats will require more break in, and others less but please remember composite bat life spans are directly related to how many impacts it receives. Each "Break In" hit takes away overall life of the bat! Once broken In, we recommend that you save you bat for Game Use Only.

What are the Different Bat Certifications?

Choosing the right bat means knowing your league’s certification requirements. At Diamond Sport Gear, our Baseball & Softball Bat Certifications Guide explains the major standards—USA, USSSA, BBCOR, NSA, and SSUSA—so you can swing confidently and legally. Each certification regulates bat performance, barrel flexibility, and power output to ensure safe and fair play. Whether you’re hitting in youth baseball, fastpitch softball, or slowpitch tournaments, our guide helps you understand what the stamps mean, which bats qualify, and how to select the right one for your level of play.

What does BPF mean? Bat Performance Factor (BPF) is simply the increase in the liveliness of a ball hitting a bat compared to throwing a ball against a solid wall. For example a 20% faster rebound = a BPF of 1.20. The major baseball and softball organizations have adopted the BPF standard to determine whether a bat is legal for play.


BASEBALL BAT CERTIFICATIONS

  • BBCOR (0.50 BPF): Bat-Ball Coefficient of Restitution. This certification is the standard that regulates the overall performance of adult bats used by high school and collegiate players. BBCOR measures the trampoline effect of the bat. BBCOR bats are only made in a drop 3 (-3) or minus 3 and have a 2 5/8" Barrel. Search available BBCOR Certified Baseball Bats.

  • USSSA (1.15 BPF): Bat Performance Factor measures how fast the ball comes off of the bat. 1.15 is the standard for travel baseball bats. Includes 2 1/4" Barrel, 2 5/8" Barrel, & 2 3/4" Barrel bats. Search available USSSA 1.15 Certified Baseball Bats.
  • New NTS Stamp (2020): Nothing is Changing with the Current Standard and Both Stamps are LEGAL! There is nothing to worry about the new stamp simply denotes the new bats that are tested at the NTS Facility.

  • USA Baseball (Little League): Effective on January 1, 2018, Little League Baseball will adhere to the new USABat standard. NO bats previously approved for use in Little League Play (Junior League Baseball and below) will be permitted to be used in any Little League game or practice, or other Little League function, event, or activity. USA Baseball believes that a wood-like performance standard will best provide for the long-term integrity of the game. The new bats will be designed to perform much like wood and BBCOR bats. USA Baseball bats can be 2 5/8" Barrel or smaller. For more information read our New USA Baseball Standard post. Search available USA Baseball Certified Bats.

  • INK DOT (Wood): An ink dot on a bat certifies that the wood is MLB grade. Often MLB-quality wood bats are bone-rubbed, which is the process of making a bat denser by compressing the wood. Search available MLB Ink Dot Wood Bats.

FASTPITCH SOFTBALL BAT CERTIFICATIONS

  • USA (ASA) / NSA / USSSA: Bats that meets USA (ASA)'s 98 MPH certification and the Bat Performance Factor (BPF) of 1.20 for NSA and USSSA. Almost all Fastpitch softball bats meet both standards. Search available ASA / NSA / USSSA Certified Fastpitch Bats.
  • ASA Has changed their name to USA. Both Stamps are Legal and will be the USA stamp moving forward.


  • ASA Only: Bats that only meet the ASA 98 MPH standard and NOT the 1.20 BPF standard, including the Easton Ghost.

    SLOWPITCH SOFTBALL BAT CERTIFICATIONS

    • USA (ASA) (98 MPH / ASA Only): There are two different standards for ASA for Slowpitch and Fastpitch softball governed leagues. The traditional 2004 98 MPH certification that can be found on All Association (ASA / NSA / USSSA) bats and the ASA Only 2013 certification. All association bats will perform at about 98 MPH while the ASA Only bats will preform at about 100 MPH. Search available All Association Slowpitch Softball Bats or ASA Only Slowpitch Softball Bats.

    • NSA (1.20 BPF): Bat Performance Factor for Slowpitch softball governed leagues. Bat Performance Factor (BPF) is simply the increase in the liveliness of a ball hitting a bat compared to throwing a ball against a solid wall. For example a 20% faster rebound = a BPF of 1.20. Search available NSA Slowpitch Softball Bats.

    • USSSA (Thumbprint or 220 lb Compression): Bat Performance Factor for Slowpitch softball governed leagues. Bat Performance Factor (BPF) is simply the increase in the liveliness of a ball hitting a bat compared to throwing a ball against a solid wall. For example a 20% faster rebound = a BPF of 1.20. Search available USSSA Slowpitch Softball Bats.
    • UPDATE 11/17/22: BANNED from USSSA Slowpitch Tournament Play starting 1/1/23. Still Legal for USSSA League Play. As of September 1st, 2020 Bat Manufacturers can no longer make USSSA bats to this Standard. They must meet their new 240 NTS Standard. 220 lb Bats have more pop than 240 lb compression bats!

    COMPARE BATS: Composite, Alloy & Wood

    What are the differences between Composite, Alloy & Wood Bats? A bat is more than just a hunk of metal or wood. It is a carefully-engineered tool that allows players to get the most out of every swing. Every component of the bat, from the knob to the end cap, is designed to maximize every ounce of performance. There are four main tech components you need to know for your bat: material, barrel diameter, construction and weight balance.

    Material

    One of the biggest influences on bat performance is its material. Bats are made of metal, composites, or wood. Metal and composite bats are traditionally used for youth baseball through college baseball. Wood is used throughout the professional levels, as well as for specific amateur and travel ball leagues/organizations. Traditionally in Fastpitch, bats are made from composite or alloy materials.

     

    Composite

    Composite bats are made with a layered material (often carbon fiber) that is easy to distribute, giving us the ability to make bats with a variety of swing weights, from balanced to end-loaded.

    Pros of Composite:

    • Minimize the sting from a mis-hit ball by reducing vibration to the hands
    • Often have a larger sweet spot than alloy bats

    Alloy

    Alloy is a mixture of two or more metals, and has been commonly used in baseball and fastpitch bats for years.

     Pros of Alloy:

    • Stiffer feel through the swing zone
    • More durable material and less issues with colder weather

    Wood

    ASH: Still widely popular among big leaguers, Ash provides the ultimate in flexibility due to its unique grain structure. More forgiving than Maple, Ash rarely sees multi-piece fractures when the bat breaks. Visible grain lines allow for noticeable quality, giving you the confidence you need when you step up to the plate.

    MAPLE: The species preferred by most pro players, Maple features the ultimate surface hardness and provides an unmatched sound and feel at contact. Naturally harder, Maple offers added strength at impact. Closed grains eliminate flaking commonly seen with Ash, allowing for superior durability.

    BIRCH: The fastest growing species in professional baseball, Birch features the ideal combination of surface hardness and flexibility for increased durability. Its hardness (similar to Maple) provides great sound and feel at contact. Flexibility similar to Ash allows for forgiveness on non-barrel contact, decreasing the chance of multi-piece fractured breakage. Birch is less dense than maple, giving it a lighter feel on comparable turning models.

    *Wood bats are more likely to break or crack on mishits than Alloy and Composite bats.

    Construction

    One-piece bats are one complete piece of composite or alloy and are often used by power hitters, since they provide less flex on contact.

    Multi-piece bats are comprised of two separate parts: the barrel and the handle. The handle is connected to the barrel through a transition piece in the taper area of the bat. Multi-piece construction helps minimize vibration on mis-hit balls. Those bats are preferred by contact hitters, since the two-part construction helps generate maximum swing speed without the fear of major sting on contact.

    KNOB STYLE - ROUND KNOB VS. FLARE KNOB

    Not all knobs are the same. Some bats have a more rounded knob while others feature a more gradual flare. The choice between the two simply comes down to personal preference.

     

    Wood: CUPPED VS. NON-CUPPED

    Cupping a bat is the process in which the end of the barrel is hollowed out to remove weight while maintaining length. This process creates a slightly more balanced feel to your swing and is especially effective on larger-barrel bats for increased swing speed.

     

    Wood: TURNING MODEL

    The turning model refers to the specific shape of the bat. Different turning models have different specifications. Here are the areas where turning models differ:

    • Barrel Measurement: is the diameter in the largest part of the barrel.
    • Barrel taper: indicates whether the bat has a short dramatic transition through the taper, or long transition through the taper.
    • Handle thickness: measures the diameter of the handle.
    • Knob taper: identifies what kind of taper exists for that turning model. Here are the three types.
      • No taper: handle comes straight into the knob with no flare.
      • Traditional taper: a gradual flare to the handle as it reaches the knob.
      • Max taper: an aggressive flare to the handle as it joins the knob for a wider feel in your bottom hand.

    Some Turning Model Examples Include:

    Swing Weight

    A factor you may not see, but will definitely feel is the swing weight* of your bat. Bats are often segmented by their given length and weight. The Swing weight is a determination of how a bat’s particular weight is distributed along the bat’s length. For example, you can have two bats that are 30 ounces, but that have different swing weights because the 30 ounces are distributed differently in the bat. Bats can fall along the swing weight spectrum, from light to balanced to end-loaded.

    End-loaded bats shift extra weight toward the end of the barrel, creating more whip-like action on a player’s swing and generating more power.

    Balanced bats have a more even weight distribution, allowing for potentially greater swing speed for many hitters. This is preferred by contact hitters who want more control of their swing.

    *Note - there are a variety of swing weights offered to meet player needs.

    Barrel Diameter

    The barrel is the thickest and widest part of the bat used to hit the ball. The barrel is where you want to hit the ball in order to achieve maximum performance. Barrels come in different sizes, and are measured by diameter. Barrel diameter is measured in inches and, like weight drop, certain leagues limit the size of a bat’s barrel. Please check with your league on their requirements.

    Fastpitch bats are 2 14 inches.

    Baseball bats come in multiple sizes including:

    • 34 inches
    • 58 inches
    • 2 12 inches
    • 14 inches

    Do you offer warranties?

    Yes! We are an authorized dealer for every brand that we carry so if the item is eligible for a manufacturers warranty you have one by purchasing with us! Bats and Gloves are the main items with warranties but multiple companies do warranty Catcher's Gear, Helmets, etc. If you are wondering if a item (not a bat or glove) has a warranty it is best to check the manufacturers website for their warranty policy. This is often located in the footer or their website.

    With that said, All Warranties go directly through the Manufacturer not through Diamond Sport Gear.

    How Do Bat Warranties Work?

    There are a few things you need to have. You can always register your bat on the manufacturers website so you don't have to keep all of your info. Every new bat comes with a warranty information card under the wrapper, we recommend you keep it in case you need to use it. All Warranties go directly through the Bat Manufacturer not through Diamond Sport Gear. Once a wrapper is off of a bat we cannot take it back.

    • You will need Valid proof of purchase or a copy of your receipt from an Authorized Dealer (Again, we are an Authorized Dealer for every brand we carry). If you lose yours please contact us we can always send you another copy!
    • IMPORTANT NOTE: Most 3rd Party Sellers are NOT Authorized Dealers! This Includes Amazon, eBay, Walmart, Facebook, etc. If you are ever in question you can contact the Manufacturer of the model you are looking at and verify that the dealer you are wanting to buy from is in fact an Authorized Dealer.
    • You have a 1 Year  Warranty from date of purchase (not when you begin using the bat). Warstic is 9 Months.
    • Warranties are 1 Year, 1 Bat. Meaning you get one replacement within the year and the one you get will be stamped "No Warranty" or "No Replacement". Some manufacturers may replace bats more than once with extenuating circumstances, but they do not have to.
    • You will need your model number and size. Which can both be found on the bat.
    • VOIDING YOUR WARRANTY: If you use illegal break in processes like Rolling or Shaving a bat, use it in too cold of weather or hit pitching machine dimple balls you void your warranty. Please read the manufacturers policy on their websites for more information on what they cover.


          Does My Glove Have a Warranty?

          First and foremost not all gloves come with a warranty. For those that do, all Warranties go directly through the Glove Manufacturer not through Diamond Sport Gear. Once a glove has been used and/or conditioned we cannot take it back.

          • The following companies offer Glove Warranties: Nokona, Wilson, Rawlings, Louisville Slugger, All Star & Diamond. There are certain rules for each brand to be eligible which are listed below. One common rule from all of them is DO NOT Bake or Steam Your Glove. It immediately VOIDS the Warranty!
          • Most do NOT cover laces for their warranties.
          • You will need Valid proof of purchase or a copy of your receipt from an Authorized dealer (We are an Authorized Dealer for every brand we carry).
          • IMPORTANT NOTE: Most 3rd Party Sellers are NOT Authorized Dealers! This Includes Amazon, eBay, Walmart, Facebook, etc. If you are ever in question you can contact the Manufacturer of the model you are looking at and verify that the dealer you are wanting to buy from is in fact an Authorized Dealer.
          • You have 1 year from date of purchase

                Where do I go to Start a Warranty Claim?

                You will have to go to the manufacturers website (DeMarini.com, Slugger.com, Nokona.com, Rawlings.com, etc.) to start the process. Their warranty policy and claims forms are often located in the footer or their website. We can always provide you with another copy of your receipt if needed. It can take some time to receive a replacement as they have to check them to make sure the item wasn't used in a way to void the warranty.

                Warranties Do Not Transfer

                If you buy a bat or glove from another parent, coach, etc the warranty does not transfer! The receipt has to be in your name. If it is someone on your team or that you know you might have to ask them to send it back on your behalf.

                We hope that this helps and if you have any questions please contact us. We'd love to help as much as we can!

                Rolling and Shaving Bats is ILLEGAL!

                Again... to be as clear & simple as possible:

                ROLLING or SHAVING a Bat is ILLEGAL! 

                Both are considered cheating and we do NOT recommend these in any way! Ultimately they will result in:

                • Legal Action: If someone is injured while using an altered bat the owner of the bat, person in the batters box and person who altered the bat are liable for the outcome and can face charges for the damages.
                • Penalties for the Player, Owner of the Bat and/or Coach including ejection, a two to five year suspension and up to a lifetime ban!
                • You Immediately VOID the Manufacturer Warranty
                • You Drastically Lessen the Durability of Your Bat

                If you are caught using a ROLLED or SHAVED bat you can receive an immediate Two (2) to Five (5) Year suspension from the governing association. If you are caught a second time you can receive a LIFETIME BAN from that association.

                What are Rolling and Shaving?

                • Rolling is the process of compressing a composite bat between two rollers to accelerate the break-in period. Occasionally used with heat to losen the composite fibers, called Heat Rolling.
                • Shaving is the process of removing the bats end-cap and shaving the insides of the bat walls to make the bat walls thinner, giving the bat far more of a trampoline effect than legally and safely allowed.

                So why do players Roll or Shave a Bat? Or more clearly why do they cheat? Quite simply they want an easy way to skip over all the hard work, dedication and patience that it takes to excel in baseball or softball.
                 
                Lets look at what the National Organizations have to say about Rolling and Shaving:

                 

                ASA / USA Softball (Including NCAA)

                Rule 3 H - Altered Bat: An ASA Official Bat's characteristics shall remain fixed at the time of manufacture and may not be altered in any way other than specifically provided for in Rule 3, Section 1 or as specifically approved by the ASA. Approved bats shall be considered altered if they are rolled, shaved, repainted, weighted or modified to change their characteristics from that produced by the manufacturer. Identifying the bat by means of laser marking, engraving, or painting the name or number of the player will not make the bat an altered bat.

                 

                Article 310 N 07: Any person discovered using a non approved bat shall be ejected from the game and are subject to further action by the protest committee.

                Article 305 E 04: A Player found in possession of an altered bat and found guilty according to Article 305 of this Code shall be suspended for a five ( 5 ) year minimum.

                Article 305 E 05: Team discovered to have with in its possession or control of an altered bat may be suspended for a two ( 2 ) year minimum. 

                 

                NSA (National Softball Association)

                Rule 3: An altered bat is considered altered when the physical structure of the legal bat has been changed in any way, or when an illegal or non-approved bat has been made up in such a way as to appear to be a legal bat. Examples of altering a bat are, but not limited to the following: Painting a bat, replacing the handle, rolling, compressing the bat in any way that is not done during the act of batting/hitting a softball or shaving the handle or barrel or the taper changed in any way such as by sandpapering or applying a solvent to the surface such as fingernail polish remover or by any other means, removing or replacing the plug or changed in any way other than factory repairs, had the knob removed/replaced or changed in any way or had anything removed or added to the inside or outside of the bat other than the legal way to tape the bat the specified and appropriate place as described in the NSA Rule Book.

                The offending player(s) will have two choices only:

                1.  He/she can allow the NSA representative to inspect the bat or ball and the NSA representative can reach a conclusion as to whether the bat or ball may be altered or he/she can refuse to allow the representative to inspect the bat or ball and take an immediate five (5) year suspension from any and all NSA play with no right of appeal. In addition to the immediate five (5) year suspension by the offending player and/or team, failure to allow a site inspection of the bat or ball or failure to allow the bat or ball to be sent into the NSA National Headquarters for further inspection, will result in forfeit of the game in progress, and forfeiture of all remaining games in the tournament; WITH NO REFUND of entry fees.
                2. He/she may after allowing the NSA representative to inspect the bat or ball and the NSA Representative has decided that the bat or ball “could be” altered; the player may allow the director to send the bat or ball to the NSA National Headquarters for inspection. If the NSA National Headquarters decides that the bat or ball may be altered, the NSA will then send the bat or ball to the Manufacturer of the bat or ball for a final determination on whether the bat or ball is altered, or he/she can accept an immediate two (2) year suspension without the right of appeal.

                Rule 2 Section 2 E: Altered Bat Director Inspection and Suspension.
                A USSSA Director may at any time ask to inspect a bat that has been brought into the location of a USSSA sanctioned event or any other USSSA facility. The owner and/or user may either:

                1. Withhold the bat from inspection and accept an immediate two year (automatic life for second time offenders under EI and/or E) suspension from USSSA sanctioned activities with no right to appeal; or,
                2. Allow the Director to inspect the bat and reach a conclusion as to whether or not the bat might be altered.

                EI.Altered Bat Determination by Altered Bat Committee Chairman or Manufacturer. If, after making the inspection of a potential altered bat, the Director in his discretion decides that the bat might be an altered bat, the suspected offending owner and/or user and may either:

                1. Withhold the bat from further examination by the USSSA Altered Bat Committee Chairman or Manufacturer of the bat and accept an immediate two year (up to life for second time offenders under sections E and/or EI) suspension from USSSA sanctioned activities with no right to appeal; or
                2. Allow the Director to send the bat to the USSSA Altered Bat Committee Chairman and/or Manufacturer of the bat for a determination as to whether or not the bat is altered. If the Manufacturer or the USSSA Altered Bat Committee Chairman determines that the bat has been altered, the Altered Bat Committee Chairman in consultation with the Director who inspected the bat at the USSSA facility may suspend a first time offender for up to five (5) years from USSSA play. For a second time offender under E and/or EI, any such suspension will be for to life.

                 

                NFHS (Baseball)

                Section 3 ART. 5: Bats that are altered from the manufacturer’s original design and production, or that do not meet the rule specifications, are illegal (See 7-4-1a). No artificial or intentional means shall be used to control the temperature of the bat. No foreign substance may be inserted into the bat. Bats that are broken, cracked or dented or that deface the ball, i.e., tear the ball, shall be removed without penalty. A bat that continually discolors the ball may be removed from the game with no penalty at the discretion of the umpire.

                Section 1 ART. 3b: Prior to the start of the game, the umpire-in-chief shall receive verification from each head coach that his participants are properly equipped in accordance with NFHS rules. In addition, each coach shall verify that his participants are using only legal equipment, including bats and balls that are unaltered from the manufacturer's original design and production and that meet the provisions of 1-3-1 and 1-3-2, and helmets that meet the provisions of 1-5-1 and are free of cracks and damage.

                Section 4 ART. 1a: A batter is out when: the batter enters the batter’s box with an illegal bat (see 1-3-5) or is discovered having used an illegal bat. If the infraction is discovered before the next pitch following the turn at bat of the player who used an illegal bat, the defense may take the penalty or the result of the play;

                PENALTY: On the first violation of 4-1-3b for entering the box with an illegal bat, the penalty for an illegal bat is applied (7-4-1a) and the head coach shall be restricted to the bench/dugout for the remainder of the game. On the second violation for entering the box with an illegal bat,the penalty for an illegal bat is applied and the head coach shall be ejected. On subsequent violations for entering the box with an illegal bat, the penalty for an illegal bat is applied and the designated head coach shall be ejected. On detected violations of 4-1-3b for the use of a damaged helmet, the helmet shall be immediately removed from play.

                NOTE: The NFHS has been advised that certain manufacturers consider alteration, modification and "doctoring" of their bats to be unlawful and subject to civil and, under certain circumstances, criminal action.

                 

                NFHS (Softball)

                Section 5 ART 1c: The Bat Shall: Be free of rattles, dents, burrs, cracks and sharp edges. Bats that are broken, altered or that deface the ball are illegal. Materials inside the bat or treatments/devices used to alter the bat specifications and/or enhance performance (e.g., shaving, rolling or artificially warming the bat barrel) are prohibited and render the bat illegal.

                Section 4 ART 2: The Batter is Out: The batter enters the batter's box with an illegal bat or is discovered having used an illegal bat and the infraction is detected before the next legal or illegal pitch (only the umpire or defense may detect an illegal bat).

                PENALTY: The ball is dead immediately. All runners must return to the base occupied at the time of the pitch. When the illegal bat is an altered or non approved bat, the batter and head coach are also ejected. Runners would not return if they were put out on the play.

                 

                Why are Rolled and Shaved Bats Advertised?

                There is only one place that rolled or shaved bat MAY be allowed to be used and that is in Home Run Derbies. It is still up to the organizer of the event if they will allow them. The reason being is in a Home Run Derby there are no Defenders in the Field! Rolled or Shaved Bats should NEVER be used in any sanctioned league or tournament play.

                What Size Glove Should I Use? There are a few factors that determine what glove you should use, including your position, age, sport and preference. These are typical sizes and a great starting point but ultimately, the size of your glove comes down to what is most comfortable for you.

                GLOVE SIZING HEADER

                How is a glove measured? Fielders gloves and first base mitts are measured by starting at the top of the index finger of the glove down the finger along the inside of the pocket and then out to the heal of the glove.  Lay the tape measure across the palm of the glove, so that it folds across and into the indenture, down to the heel of the glove.  A catcher's mitt is measured by the circumference.

                Most Popular Size: 11.5"

                11.75" - 12"

                Most Popular Size: 11.75"

                Pitchers typically have about the same size as other infielders but opt for closed pockets or Modified Traps to avoid seeing their grip. You MUST avoid predominantly white or grey gloves as a pitcher as they are illegal. Shop our collection of Pitcher's Baseball Gloves

                OUTFIELD GLOVE SIZING

                12.25" - 13"

                Most Popular Size: 12.75"

                Outfielder gloves offer a larger pattern size in comparison to infielder gloves. This is due to outfielders needing a larger pocket to assist with pop flies and wanting a longer reach. Explore our collection of Outfield Baseball gloves

                FIRST BASE MITT SIZING

                12" - 13"

                Most Popular Size: 12.5"

                To be able to play first base, you need to be able to catch extremely well. Having the right sized mitt helps. First Base Mitts are larger and have a scoop to help catch anything thrown your way. Youth First Base Mitts for 12 & under are typically 12" or 12.25". View our collection of Baseball First Base Mitts

                Catcher Mitt SIZING

                31" - 34"

                Most Popular Sizes: 32.5"- 33"

                These gloves range in size from 31 inches to 34 inches. This isn't because they are three times the size of a normal glove, but rather because these mitts are measured by their circumference rather than top to bottom. Youth are typically 31"- 32.5" and Adult are 33" and up. Due to how thick the padding can be, the pocket on a 32.5" and 34" can be about the same size.

                Youth gloves are recommended for younger players who have not stopped growing and are likely to outgrow their glove sooner rather than later. The age range of youth players is 12 years old and under. Because of the wide range in age, the sizes are going to have a larger range too. The difference with youth gloves is a smaller wrist opening and tighter finger stalls for a more secure fit on a youth player's hand. View our collection of Youth Baseball Gloves.

                What Size Fastpitch Softball Glove Should I Use?

                There are a few factors that determine what glove you should use, including your position, age, sport and preference. These are typical sizes and a great starting point but ultimately, the size of your glove comes down to what is most comfortable for you. Due to the larger softball being used, Fastpitch softball gloves for both infield and outfield feature a larger pattern in comparison to baseball gloves. But, similar to youth gloves, a lot of models will feature a smaller wrist opening and tighter finger stalls to accommodate a female athlete's hand.

                    How do you Care for & Break in your Glove?

                    Your glove is one of the most important pieces of gear on the field—and proper care keeps it performing at its best. At Diamond Sport Gear, our Glove Care & Break-In Guide shows you how to soften, shape, and maintain your baseball or softball glove the right way. From choosing the best break-in method to cleaning and conditioning leather, our step-by-step tips help you preserve your glove’s fit, flexibility, and durability. With consistent care, your glove will mold perfectly to your hand and deliver reliable performance for many seasons to come.

                    How to Break in Your Glove

                    The best way to break in a glove is to use specially designed glove oil.  Glove oil keeps the leather ''alive'' while providing a softening condition and minimizing weight gain.  Apply a small amount of glove oil to a sponge or cloth, then use the sponge or cloth to apply the oil to the areas of the glove that are currently firm. Start with the palm, the break point of the glove and then web. Then use the glove oil on all other parts of the glove including the entire inside to help moisturize and protect the glove.  Work the glove oil into the leather evenly.  Do not apply the glove oil directly to the glove, as it will be too concentrated at the point of application.

                    Also, make sure that the laces get oiled so they can stay moisturized so they will not dry and begin to crack. Otherwise, the webbing of the glove will come loose.  Remember that leather is skin and leather experts tell us not to treat glove leather any differently than you would your skin. Therefore prolonged harsh temperatures (oven, microwave) excessive water soaking, especially use of hot water, abrasives, the salt and acids produced from perspiration and excessive dryness all or individually can be harmful to the glove leather.

                    Break In Quick Tips

                    • Play Catch!
                    • Use a Glove Mallet to simulate repeated ball impacts
                    • If you have access to a pitching machine stand and catch the balls and drop them in a bucket, breaks in the glove and works on hand eye coordination
                    • Keep your hand in the glove to break it it! If you let someone else break it in, it will fit their hand not yours!
                    • While watching TV or sitting keep throwing a ball into your glove.
                    • Constantly move the leather to help it loosen up.
                    • Don't add a lot of Oil or Conditioner! The more you add the heavier the glove becomes!
                    • DO NOT BAKE OR STEAM A GLOVE!!! It is a quick fix but will destroy the leather and drastically shorten the life of your glove!

                     

                    General Glove Care

                    A properly cared for quality glove will perform for many seasons. Improper handling, cleaning, adjusting and, in particular, over oiling can shorten the life expectancy of your glove. The most important part of caring for your glove is to recognize that leather will deteriorate if subjected to repeated exposure to moisture and heat. MOISTURE (Water / Steam) and HEAT (Oven / Baking) are the worst things for a leather glove.

                    • Use the glove oil sparingly, as you can always add more.
                    • NEVER put your glove in an oven or microwave, the heat can damage the fibers of the leather.
                    • Water / Steam will cause the leather to dry out, crack, and the laces to become brittle. Some stores will steam for you, in a pinch it works for a weekend but not the long term as it drastically reduces the life of the glove.
                    • Applying glove oil to any non-black colored leather will likely darken it considerably.
                    • Excessive glove conditioner/oil will damage and shorten the life of a new glove.
                    • Allow the glove oil to absorb into the leather for 24 hours in a warm area, temperature between 70-90 degrees.
                    • At the end of the season, apply glove oil very lightly to keep your glove from becoming brittle.
                    • Store your glove in a dry place with a ball in the pocket to maintain shape.
                    • Do not use neat's-foot oil, linseed oil or silicon-type spray, these tend to close the pores of the leather, causing it to dry, harden and become heavy.
                    • Do not apply the glove oil directly to the glove, as it will be too concentrated at the point of application, apply to a cloth first.
                    • Pummeling a new glove speeds up the break-in, but the glove will be better served if this extra abuse is avoided.
                    • Wearing a batting glove under your glove absorbs moisture and prolongs the life of the liner of the glove.

                    Leaving your glove out in the weather will ruin it, as will putting it away wet from perspiration. If it is comfortable, wear a batting glove under your baseball glove (unless you are a baseball pitcher); this absorbs the sweat from your hand. This could add years to the lining of your glove.

                    When your glove gets wet, dry it with a towel or soft cloth, and leave it exposed to room air for a few hours until the lining is dry. After it dries, use a little glove oil to moisten the leather. When you put your glove away, it's best to put a ball or two in the pocket to help keep its shape.

                    Routine maintenance should probably be done at least once a season so that you can check the condition of the glove. A tune-up involves tightening the laces in the fingers and web; re-tying any loose knots and cleaning, conditioning and shaping the glove. If you find torn seams, split leather, or broken laces, be sure to have them repaired as quickly as possible. Playing with a damaged glove can damage the glove further and even cause errors. The off-season is also a good time to have the glove professionally re-laced if it requires this work. A number of companies offer this work in addition to complete rebuilding and repair services. At the end of the season, you can take a moderate amount of petroleum jelly, and cover the outside and inside of the glove. Don't ignore the laces or hard-to-get-to areas, both inside and outside the glove. Then take a clean rag and wipe off excess to remove grit and grime. This will also remove and help neutralize much of the salt and acid buildup inside the glove caused by perspiration, a chief problem to the leather lining, usually made of softer leather.

                    • You have a 1 Year  Warranty from date of purchase (not when you begin using the bat). Warstic is 9 Months.
                    • Warranties are 1 Year, 1 Bat. Meaning you get one replacement within the year and the one you get will be stamped "No Warranty" or "No Replacement". Some manufacturers may replace bats more than once with extenuating circumstances, but they do not have to.
                    • You will need your model number and size. Which can both be found on the bat.
                    • VOIDING YOUR WARRANTY: If you use illegal break in processes like Rolling or Shaving a bat, use it in too cold of weather or hit pitching machine dimple balls you void your warranty. Please read the manufacturers policy on their websites for more information on what they cover.


                          Does My Glove Have a Warranty?

                          First and foremost not all gloves come with a warranty. For those that do, all Warranties go directly through the Glove Manufacturer not through Diamond Sport Gear. Once a glove has been used and/or conditioned we cannot take it back.

                          • The following companies offer Glove Warranties: Nokona, Wilson, Rawlings, Louisville Slugger, All Star & Diamond. There are certain rules for each brand to be eligible which are listed below. One common rule from all of them is DO NOT Bake or Steam Your Glove. It immediately VOIDS the Warranty!
                          • Most do NOT cover laces for their warranties.
                          • You will need Valid proof of purchase or a copy of your receipt from an Authorized dealer (We are an Authorized Dealer for every brand we carry).
                          • IMPORTANT NOTE: Most 3rd Party Sellers are NOT Authorized Dealers! This Includes Amazon, eBay, Walmart, Facebook, etc. If you are ever in question you can contact the Manufacturer of the model you are looking at and verify that the dealer you are wanting to buy from is in fact an Authorized Dealer.

                                Where do I go to Start a Warranty Claim?

                                You will have to go to the manufacturers website (DeMarini.com, Slugger.com, Nokona.com, Rawlings.com, etc.) to start the process. Their warranty policy and claims forms are often located in the footer or their website. We can always provide you with another copy of your receipt if needed. It can take some time to receive a replacement as they have to check them to make sure the item wasn't used in a way to void the warranty.

                                Warranties Do Not Transfer

                                If you buy a bat or glove from another parent, coach, etc the warranty does not transfer! The receipt has to be in your name. If it is someone on your team or that you know you might have to ask them to send it back on your behalf.

                                We hope that this helps and if you have any questions please contact us. We'd love to help as much as we can!
