ASA Slowpitch Balls
 

I don't work slowpitch anymore, but I was asked by a friend. What is the official ASA ball(s) for Coed Slowpitch? He told me a team showed up with some brand new 52 COR balls. I told him I have never seen any 52 COR balls but I vaguely recall reading something about them. So what is the approved balls for ASA Coed slowpitch?
Thanks.

USA slowpitch men's use 12 inch .520 COR balls Women use 11 inch .440 COR balls. The balls alternate each batter in coed.

Beginning in January 2017 the 11" with a Ball COR of .520 or under and a Ball Compression of 300.0 or under is required.

Thanks!
