The One-Hand 18” Training Bat from Louisville Slugger features a standard-sized barrel, meaning hitters can use the bat for tee work and one-arm hitting drills. Mimic a natural swinging motion with one arm, improving comfort and stability at the plate with every repetition. Hone in in on your swing and fine-tune your mechanics so you can send a pitch to the bleachers when you step up to the plate in games.
