Beginning in the 2027 season, the MCSSA will officially adopt the USSSA 240 bat standard for league play. That means all bats must have the newer (created in 2020) USSSA 1.20 bat stamp. If you have an older 220 bat, you will no longer be able to use it starting the 2027 season.
A huge THANK YOU to Spectrum Studios for their continued support of the MCSSA by way of meeting space and helping with t-shirts.
