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

2026 Marucci Block Party USSSA Slowpitch Softball Bat 2 Piece 13" Barrel MSPBP2BU (MSPBP2BU) — The biggest, lightest-swinging Block Party — a 13" barrel with balanced weighting for speed, precision, and barrel control.

Description

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.

Who This Bat Is Built For

Best for:

• USSSA/ISA/NSA slowpitch hitters who play the game hard but love bats with personality. The contact hitter who prioritizes bat speed and plate coverage over raw end-load damage. The gap-to-gap sprayer working the whole field, the leadoff-style hitter who thrives on quick hands, and the hitter who wants the biggest legal 13" barrel in the lineup without slowing down the swing. Available in 25oz (quickest swing speed — built for plate coverage, line drives, and contact hitting), 26oz (added authority without losing bat speed — balanced feel with more punch). Step in the box, trust the 13" barrel, and create your own chaos.
