A mechanical device propels baseballs at a reduced speed over a short distance. This allows batters to practice their swing mechanics and timing in a controlled environment, focusing on specific aspects like hand-eye coordination, bat control, and consistent contact. A common example is a pitching machine that feeds balls from a close proximity, often with an adjustable arc and speed.
Repetitive, close-range practice provides numerous advantages for skill development. It allows athletes to groove their swing, build muscle memory, and improve hitting consistency. This type of training is especially valuable for beginners learning fundamental techniques or experienced players honing specific skills. The evolution of these devices has provided a valuable training tool, augmenting traditional practice methods and contributing to improved performance.
