Engineered with a high-flex composite barrel and tuned stiffness throughout the bat, the Gridlock USSSA Slowpitch Bat delivers explosive response without sacrificing feel. It's a forgiving one-piece bat that plays hot from day one and keeps performing long after the wrapper comes off.\n\n2026 Marucci Gridlock Red 12.75\" USSSA Slowpitch Bat\n\nThe Gridlock Red is a one-piece composite USSSA slowpitch bat built for hitters who want a traditional swing feel with a loaded, end-weighted punch. A high-flex composite layup and Modulated Stiffness Technology (MST) work together to widen the sweet spot and keep the barrel hot from the very first at-bat.\n\nSpecifications\n\nOne-Piece Composite Construction\n\nA continuous composite layup from knob to endcap for a clean, consistent, and traditional swing feel.\n\nLoaded Swing Weight\n\nA slightly end-loaded feel that suits a wide range of hitters looking for extra pop through the zone.\n\nBarrel Diameter\n2 1\/4\"\n\nBarrel Length\n12.75\"\n\nConstruction\nOne-Piece Composite\n\nSwing Weight\nLoaded\n\nHandle\nMid Stiff\n\nCertifications\nUSSSA, NSA, ISA\n\nWarranty\nOne year\n\nModel Number\nMSPGLR1LU\n\nGrip weight and manufacturing tolerance may cause slight deviation from the listed weight.\n\nX1B Barrel Technology \u0026amp; Modulated Stiffness (MST)\n\nX1B Barrel Technology is a precision-engineered single-piece construction with a high-flex composite layup built for feel, forgiveness, and deep trampoline response. Modulated Stiffness Technology (MST) connects the barrel and handle in a way that fine-tunes how the bat flexes — adjusting materials in key areas to balance flex and stiffness for better energy transfer, control, and feel at every point of contact.\n\nTechnical Features\n\n•\nHigh-Flex Composite Layup — Barrel wall engineered for deep compression and a pronounced trampoline rebound at contact, producing a soft, low-vibration response across the full hitting surface.\n\n•\nSingle-Piece Composite Architecture — Continuous layup from knob to endcap eliminates connection points, maintaining consistent stiffness distribution and direct energy transfer throughout the barrel.\n\n•\nOptimized Flex Gradient — Barrel wall transitions from stiffer zones near the taper and endcap to high-flex zones at the sweet spot, widening the responsive hitting surface.\n\n•\nHot Out of the Wrapper — Fiber and resin combination breaks in rapidly, delivering game-ready performance without an extended break-in period.\n\nPlayer Benefits\n\n•\nSoft, Forgiving Feel at Contact — High-flex barrel construction produces a cushioned, low-vibration response that hitters looking for feel and forgiveness will notice immediately.\n\n•\nGame-Ready from Swing One — Fast-acting fiber and resin tuning means full barrel performance without a lengthy warmup period.\n\n•\nExpanded Sweet Spot — Layered fiber architecture compresses across a wider surface area, producing consistent pop on off-center contact.\n\n•\nTraditional One-Piece Feedback — Direct handle-to-barrel connection provides immediate feedback and maximum force return on squared-up contact.\n\n•\nLong-Lasting Pop — Advanced fiber and resin systems extend usable barrel life without sacrificing performance.\n\nShop the Full 2026 Marucci Gridlock Lineup\n\nThe Gridlock Red is one of four bats in Marucci's 2026 Gridlock slowpitch lineup.

This bat is certified for USSSA, NSA, and ISA play, so it's approved for the vast majority of USSSA-sanctioned slowpitch leagues and tournaments.\n\nWhat is the swing weight of this bat?\n\nThe Gridlock Red is a loaded bat with a slightly end-loaded feel, giving it extra momentum through the hitting zone while still remaining manageable for a wide range of swing speeds.\n\nDoes the bat need a break-in period?\n\nNo. The fiber and resin combination in the X1B composite barrel breaks in rapidly, so the bat plays hot right out of the wrapper without an extended warmup period.\n\nWhat's the difference between the one-piece and two-piece Gridlock bats?\n\nThe one-piece Gridlock Red delivers a traditional, direct handle-to-barrel feel with immediate feedback on contact. The two-piece models in the lineup, like the Cobalt Blue and Sublime Lime, isolate vibration at the connection point for a different feel profile.\n\nDoes this bat come with a warranty?\n\nYes, the Gridlock Red USSSA slowpitch bat includes a one-year manufacturer's warranty.","brand":"Sports Performance Park","offers":[{"title":"25oz","offer_id":58562149646710,"sku":"MSPGLR1LU-25","price":135.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/6640\/0374\/files\/MSPGLR1LU_A.jpg?v=1787962990","url":"https:\/\/sportsperformancepark.shop\/products\/2026-marucci-gridlock-loaded-usssa-slowpitch-softball-bat-mspglr1lu","provider":"Sports Performance Park","version":"1.0","type":"link"}
