Church / city rec league Local leagues bat rules (2027)

Varies by event. Bat rules here can change by state, event or league. Check your event's or league's rules before you buy.

There's no national rule. Many rec leagues follow USA Softball, some allow USSSA or both, and some ban senior bats. Check your league's bylaws before you buy.

What the stamps mean

• USA Softball mark (ASA 2000, ASA 2004 or USA Softball "All Games"): The most widely required fastpitch stamp. USA Softball events also require the bat to be on the approved list and off the non-approved list. The ASA 2013 mark isn't legal for girls' or women's fastpitch. Official list.

What size slowpitch bat?

Nearly all slowpitch bats are 34". Weight is the real choice: 26–28 oz suits most hitters.
