Mizuno CRBN X -9 Fastpitch Softball Bat 340691  

The 2026 Mizuno CRBN X -9 Fastpitch Softball Bat 340691 is built for power hitters who want maximum impact, a heavier feel, and explosive performance at the plate. Designed with Mizuno’s one-piece Detonator Cor™ construction, this fastpitch softball bat delivers a stiff, solid swing that transfers more energy directly into the ball for harder contact and deeper drives. The Black Onyx Carbon™ barrel and handle create a durable, game-ready build with a quicker break-in period, so hitters can step in with confidence from day one. With its -9 drop, this model is ideal for stronger players looking to generate serious pop while maintaining control through the zone. Available at SPC Sports, the CRBN X -9 is built for players who want to swing with authority and change the game with every at-bat.
