The rules we play by.

Every tournament has its own rulebook. Here's a quick look at the ones on our schedule, with links straight to the official versions.

Checked October 4, 2026. Both play high school (NFHS) rules with their own changes. If anything here disagrees with the official rules, theirs win.

Is my bat legal?

Both tournament series take a bat with the USSSA 1.15 BPF stamp or the USA Baseball logo, and wood is always fine. Look for the stamp printed on the bat itself: a sticker doesn't count. Check a specific model on the official lists.
