ProNine 44 YSC Slowpitch Softballs - 12 Inch Optic Yellow - Dozen

The ProNine 44 YSC is the everyday optic yellow slowpitch dozen: a 12 inch slowpitch softball with a optic yellow synthetic tacky grip cover, medium seam height, and a solid polyurethane center built to 44 COR and 375 lb compression. It will not dent bats, which matters when the whole league swings composite. Sold by the dozen.

Built for Slowpitch Reality

Slowpitch softballs live a violent life: big swings, composite barrels, long seasons. The synthetic tacky grip cover holds up where leather scuffs open, the poly center keeps its pop, and the 44 COR and 375 lb compression build delivers the flight slowpitch players expect.

Where It Fits

The 44 WSC is the white-cover twin for leagues that play white. USSSA leagues should head straight for the USSSA Classic series, and the whole wall lives in the slowpitch softballs collection.

What does the COR number mean?

Coefficient of restitution (COR) measures bounce and the compression rating measures hardness; together they set how hot the ball plays. Leagues specify these numbers, so match your league sheet: this ball is 44 COR and 375 lb compression.

Yellow or white?

Optic yellow dominates modern slowpitch for visibility; some leagues and tournaments still call for white. Buy what your league plays.
