Mizuno B21 PWR Carbon BBCOR Baseball Bat (-3)


Put the new Mizuno B21 PWR Carbon BBCOR Baseball Bat (-3) two-piece bat, next to any other bat and its extended barrel shape stands out.

This larger hitting area and sweet spot, however, is just scratching the surface of this high-performance bat.

Inside the massive barrel is Mizuno’s exclusive Detonator Cor™ technology, which results in lower barrel compression, more power, and a booming sound at contact.

A low MOI design makes this a perfect bat choice for players looking for a truly balanced bat.

  • Detonator Cor™: Mizuno's Patent Pending design creates low barrel compression for great performance while improving impact sound.
  • Dual Frequency Damper™: Mizuno's patent-pending construction combines two different materials for vibration reduction and less flex for higher performance.
  • Black Onyx Carbon™: Increased durability with a shorter break-in period.
  • Cylinder Seaming: Allows for consistent performance and durability across the barrel.
  • Stiff Carbon Handle: Reduces energy loss when impacting the ball at higher ball speeds to put more energy where it belongs (the ball) and less where it doesn't (the handle and your hands).
  • Speed-Helix Grip: Designed to provide comfort and durability.
  • BBCOR Certified: Approved for NCAA/NFHS play.
  • Bat Barrel Diameter: 2 5/8 inches
  • One Year Warranty: Warranted from defects in materials and workmanship for a period of one year from the date of purchase.
