The 2021 5150 USA bat is crafted entirely from composite material, making it extremely lightweight for quicker swing speeds and improved trampoline effect for greater pop. Its 2 5/8” large barrel design offers a huge sweet spot, simplifying contact. This -11 drop weight bat is tailored for players aged 12 and under aiming to catch up to faster pitches and enhance contact rates from the first swing. It is constructed from Rawlings' 5150 Alloy, our most responsive, aerospace-grade alloy designed for performance and durability. This bat is fully approved for use in all USA Baseball sanctioned leagues.
