Coming in hot. The 2021 The Goods One Piece USSSA (-10) Baseball Bat makes its debut in the USSSA lineup this year, bringing the same jaw-dropping performance that made it a staple in DeMarini’s BBCOR offerings. A massive X14 Alloy Barrel with the one-piece design gives you the feel of a wood bat with explosive power. The Seismic End Cap is made of the stiffest materials in the lineup, meaning no energy is wasted in your swing. Domination starts here.
