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.
