Slowpitch bat for HS softball ?

[Rutgersfan]

Is there a hs legality difference between bats marketed as slowpitch and those sold as fastpitch if both show the same ASA 2004 marking ?

[The Man in Blue]

Yes.  From USA Softball's 2024 rule book:

As long as it has the appropriate marking, it is OK.  Not all USA Softball marks are OK though.

For NFHS, you need one of the marks on the left.  If it has that mark, even if it says slow pitch, it is OK. 

If it has a mark from the right, it is illegal.
