2026 Marucci Block Party 13" Balanced USSSA Slowpitch Softball Bat: MSPBP2BU

Built to smash—without sacrificing speed. The Block Party USSSA Slowpitch Bat – 13” 2PC Balanced (MSPDR2LU)is inspired by the iconic world of colorful building bricks and engineered for players who love to create their own chaos with precision, barrel control, and repeatable bat speed. This two-piece composite blends feel, flex, and pop in one dangerous package, featuring Block Party’s lightest barrel for your best swing every time.

At the core is DisRupt Duo Barrel Technology, delivering hot, forgiving, controlled performance with optimized comfort from a two-piece build. Multi-Layered Barrel Engineering uses a hybrid composite layup with impact-toughened structure to tune flex and rebound, while the connection is designed for optimized handle-to-barrel energy transfer—letting the barrel work while isolating vibration. A dynamically tuned flex profile helps the barrel flex slightly deeper than the Mono design for added whip, and a resin-infused toughening layer boosts fatigue resistance so the performance stays consistent. With an engineered sweet spot expansion (variable wall thickness + layered fibers), you get a broad, forgiving zone that stays lively on mishits. Finished with Modulated Stiffness Technology (MST) to fine-tune flex and stiffness through key zones, this balanced 13” two-piece is built to respond to your swing—every cut, every count.
