FirstStrike Wheeled 6-Inch Portable Pitching Mound is a full-size, portable pitching mound built for pitchers ages 10 and under. It delivers regulation 6-inch height and a full-length stride area with a true one-inch-per-foot slope, so young pitchers train on real mechanics — not backyard habits.

Built to Regulation 6-Inch Specs for Youth and Little League

The FirstStrike matches official youth and Little League mound height requirements. Its true one-inch-per-foot slope develops the downhill mechanics young pitchers need to build a foundation before moving up in age and competition level.

Full-Length Stride Area for Real Pitching Mechanics

The FirstStrike's full-length 7.5-foot landing zone gives young pitchers room to complete their stride and follow-through naturally. Short or undersized mounds force compensations that become bad habits. FirstStrike Wheeled 6-Inch Portable Pitching Mound eliminates that problem from the very first rep.

Rolls to the Field — All 91 lbs Feels Like 35

The Stow & Throw™ wheel system uses oversized 12-inch solid PVC wide-track wheels with an axle that distributes weight evenly across the mound — so 91 lbs rolls like 35. Quick-release stainless steel pins stow the wheels flush underneath for storage. It fits in an SUV and sets up in under a minute.

Built from Exterior-Grade Baltic Birch with Marine-Grade Hardware

Every component of the FirstStrike Wheeled 6-Inch Portable Pitching Mound is engineered for outdoor durability — exterior-grade Baltic Birch core, 316 marine-grade stainless steel hinges, 304 stainless steel push-button quick-release pins, waterproof Titebond III glued joinery, and waterproof nylon bolts. Optimized for turf shoes.

Features Built for Serious Training

  • Stow & Throw™ Wheels — oversized 12" solid PVC wide-track wheels with internal bearings roll smoothly across dirt, grass, and pavement
  • Professional-Grade Pitching Rubber — regulation-size rubber for authentic mechanics development
  • Comfort Grip Handle — heavy-duty non-slip handle with ergonomic polypropylene webbing
  • Adjustable Draw Latches — customizable tension latches keep the mound locked tight during transport
  • Flush-Mount Stainless Steel Hinges — corrosion-resistant, flush hinges prevent tripping hazards
