The Marucci Gridlock 12.75” USA/ASA One-Piece Loaded Slowpitch Bat is built for hitters who want a clean, traditional swing feel with added weight through the barrel. Its slightly endloaded design provides extra power potential without creating an overly demanding swing profile, making it suitable for a wide range of slowpitch hitters.
DisRupt Dual Chamber Barrel Technology combines a soft, low-compression outer barrel with a fully suspended, full-length inner barrel. These independently tuned barrel walls work together to create explosive rebound, consistent distance, and an expanded sweet spot across the hitting surface.
Modulated Stiffness Technology fine-tunes how the barrel and mid-stiff handle flex throughout the swing. The result is improved energy transfer, control, and feel in a one-piece composite bat designed to deliver game-ready performance from the first swing.
