2026 Marucci Block Party USSSA Slowpitch Softball Bat 2 Piece 13" Barrel MSPBP2BU

2026 Marucci Block Party Balanced USSSA Slowpitch Softball Bat – MSPBP2BU

The biggest, lightest-swinging Block Party — a 13" barrel with balanced weighting for speed, precision, and barrel control.

Marucci's 2026 Block Party USSSA Slowpitch bat (MSPBP2BU) is built for the player who doesn't take softball too seriously — but absolutely takes smashing the ball seriously. Inspired by the iconic world of colorful building bricks, this lineup is designed to let you assemble your own chaos swing after swing. Two-piece composite construction blends feel, flex, and pop into one dangerous package. The 13" DisRupt Duo Barrel with DisRupt Duo Barrel Technology uses a multi-layered hybrid composite layup engineered for deeper barrel flex than a one-piece, adding trampoline and whip through contact — great for players with varying swing speeds who still want to drive the ball. Balanced weighting is our lightest-barrel profile in the Block Party family — built for speed, precision, and barrel control so you can put your best swing on every pitch. The High Flex handle tuned by Modulated Stiffness Technology (MST) keeps the barrel responsive while the 13" length gives you the biggest hitting zone allowed in USSSA slowpitch. Finished in a red, blue, and yellow building-brick graphics with a smiley-face endcap, the Block Party is ready straight out of the wrapper (peaks after 100–200 quality swings) and fully certified for USSSA, ISA, NSA play.
