2026 Marucci Gridlock 12.75" Endload 1PC USSSA Slowpitch Softball Bat: MSPGLR1LU

The Marucci Gridlock USSSA Slowpitch Bat – Red 12.75” 1PC Loaded is built for hitters who want a traditional one-piece swing with a forgiving barrel and slightly endloaded feel. Its continuous composite construction delivers direct feedback and consistent energy transfer from the handle through the barrel.

X1B Barrel Technology uses a high-flex composite layup to produce deep compression and pronounced trampoline response at contact. The optimized flex gradient creates a wider responsive hitting surface, helping generate consistent pop while maintaining a soft, low-vibration feel.

Modulated Stiffness Technology fine-tunes the flex and stiffness throughout the bat for better control, feel, and energy transfer. With game-ready performance from the first swing and a loaded profile suited to a wide range of hitters, the Gridlock is ready to perform without an extended break-in period.
