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.

OPTION GUIDE: Should I order this bat stock/untouched or Heat Rolled with Progressive Pressure?
If you order your new bat Heat Rolled with Progressive Pressure, it will be delivered to you completely and evenly broken in. This process adds 20-40ft of distance to your solid hits, increases consistency, improves durability and adds 2-3 business days of lead time to your order. If you plan to use the bat in an official game or event, please verify the legality of our process with your league or sanctioning body before use.
