40 COR 375 compression Thunder Heats.
Still the umps call right?
rule book wise every ball is to be yellow and that has not happened yet.
so is the 40 cor 375 still an ump call or flat out no.

Might be a league rule that allows it.
The league I played in used the 40/375 balls for a few years. It was a very good ball.
We are now using sb12 or 52/300 balls.
