2026 Marucci Gridlock Red USSSA Slowpitch Softball Bat Loaded 12.75" Barrel

2026 Marucci Gridlock Red USSSA Slowpitch Softball Bat Loaded 12.75" Barrel MSPGLR1LU (MSPGLR1LU) — The Gridlock one-piece – X1B barrel, loaded swing weight, and a mid-stiff MST handle for hitters who want it direct.

Description

The 2026 Marucci Gridlock Red is the one-piece power option in the Gridlock slowpitch line. The 12.75" barrel runs Marucci's X1B barrel technology for a responsive, hot hitting surface, and the loaded end weight puts extra mass behind every swing. Because it's a single-piece build, energy goes straight from your hands to the ball – no connection point, no loss – while Modulated Stiffness Technology (MST) in a Mid Stiff profile fine-tunes how the bat flexes so the direct feel never turns harsh. Finished in black with red and white cracked-grid graphics, offered in 34"/25, 26, and 27 oz, certified USSSA 1.20 BPF, NSA, and ISA, and backed by a 1-year manufacturer warranty.
