Mizuno MB380FS Baseball

The Mizuno MB380FS is a flat-seam leather baseball built to Mizuno's exacting standards for practice and machine use. Crafted from a premium full-grain leather cover over a cushioned cork center, it delivers authentic feel, superior grip, and the durability coaches expect from a ball that sees heavy reps. The hand-sewn flat seams sit low to the cover, making the MB380FS ideal for pitching machines and long practice sessions where raised seams cause extra wear. Sold by the dozen, it's a smart, cost-effective choice for stocking the bucket for batting practice, bullpens, and fielding drills.
