COR & Compression in softballs refers to the ball's hardness and bounce. Compression is rated by how many pounds of force (like 300, 400, 475) compress it a quarter-inch. The higher numbers mean harder balls for more distance, while lower numbers are softer for limited flight, safer play or training. These compression ratings work with the Coefficient of Restitution (COR) (e.g., 52, 47, 44) to determine bounce, with lower COR/higher Compression balls being harder and bouncier for competitive play.
NOTE: Softballs have a 25± compression variance. So, they could be up to 25 points above or below the certified compression.
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! With that said, All Warranties go directly through the Manufacturer not through Diamond Sport Gear.
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 warranty information under or on 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 have to go to the manufacturers website (DeMarini.com, Slugger.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.
If you buy a bat 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!
