The Worth YBPCP Lithium Prodigy -10 Youth Baseball Bat is made with Worth's strongest aluminum allowing for thinner walls and shells for maximum trampoline effect. With X-tended sweetspot technology the Prodigy has the largest sweetspot in the industry on aluminum bats extending the barrel 1 « to 2 inches longer. The 2 3/4 inch diameter big barrel bat has a whiplash frame with up to 30% thinner taper walls for reduced weight and increased bat speed. It is center loaded with an endplug designed to allow barrel flexibility and 5% more inertia to drive through the ball. The Lithium Prodigy also features a silencer leather grip for sting and vibration reduction.
