This Senior League Prodigy Alloy baseball bat features a high-strength, high performance aerospace-grade alloy. The 2 3/4" big barrel and extended sweet spot technology makes this a great bat for the price. Bats sanctioned by USSSA® are designed to not exceed the 1.15 BPF performance standards set by the association. The association allows 2 3/4" barrels and has no restrictions on weight drops. Approved bats receive the USSSA thumb print located on the taper.
