Pronine X4 Composite Cage Baseball

The ProNine X4 is a composite cage baseball engineered to stand up to the toughest environment in the game: the batting cage and pitching machine. Its official medium-seam design gives a natural grip and true flight, while the durable composite cover resists the scuffing and abuse that shred ordinary balls during high-volume reps. Built to keep its shape and feel through countless swings, the X4 is a smart way to protect your game balls and cut down on replacements. Sold by the dozen, it's a must-have for programs that log serious cage time.
