The sword, in maple.
A limited edition maple bat featuring Trevor's iconic sword celebration. Only 30 made.
Trevor made his living on the mound. His weapon was always the sword. This is the first time it's been turned into something you can swing: a massive barrel, a thin handle, a flared knob, and a premium paint job nothing else in the rack has.
Swing it on Sunday.
Hang it on the wall.
Either way, it's the sword.
Who's it for?
• Bauer Outage fans who already own the tee and want the next level up
• Hitters who want a massive barrel with a quick, thin handle
• Collectors who want a piece capped at 30
• Anyone who wants a bat nobody else in the league has
Pro quality maple. 32, 33, and 34 inch. $169.99.

The 4APP Plyo Ball System is a 7-piece velocity training set engineered for elite pitchers and competitive arm development. Featuring a gapless overload-to-underload weight spectrum, a humidity-resistant engineered shell, and a revolutionary half-seam dual-feel design, this system provides unmatched biomechanical grip and authentic pitch feel across all training environments.
- Humidity-Resistant Grip: Features a proprietary composite shell texture that maintains a clean, consistent hold in sweat and high heat, eliminating dangerous over-gripping.
- Dual Feel Half-Seam Architecture: Engineered with one side featuring realistic raised seams for pitch shapes, and a completely smooth side for constraint-based mechanical training.
- Cohesive Weight Spectrum: A complete 7-piece progression covering 3.5 oz up to 4 lbs, completely eliminating weight gaps for smooth biomechanical scaling.
- Optimized Rebound Control: Dialed-in wall thickness guarantees durable, controlled rebound profiles off hard facility surfaces to prevent unpredictable ricochets.
