Used by three-time American League batting champion Joe Mauer, this is the baseball hitting trainer that helps batters develop better bat speed, reflexes, and proper hitting mechanics. Eliminating the need for a practice partner, the device automatically drops a ball every six, eight, or 10 seconds, teaching batters proper swing tempo, patience, and how to hit an off-speed pitch. The included trampoline sets up under the spout and allows hitters to practice soft toss hitting, a technique used by professional baseball players to practice pulling the ball, hitting to the opposite field, and develop muscle memory for a consistent swing. Holds 12 baseballs or eight softballs (not included). The batting trainer adjusts to drop balls from 47" to 67" high. Requires three AA batteries. 52" - 72" H x 45 1/2" W. (15 lbs.)
