Fastpitch softballs vary in size and material composition depending on the league and the age of the players involved. Younger players will typically play with a 10- or 11-inch ball that has a softer core to reduce the risk of impact injury. In more advanced leagues, starting roughly around middle school, players will begin using the full size 12-inch ball with a solid core.
Select from brands like Baden, Champro, Wilson, Rawlings and Worth to find the right ball for your game. Remember to check with your league about which softballs are certified for use and if any are restricted.
