The limited flight Powernet Micro Crushers are perfect for baseball training in small-sized spaces or indoor hitting practice. Designed with durable components that can withstand the abuse of multiple seasons, the ball's flexible plastic surface compresses when hit and then pops back into shape immediately. These balls were designed to act true to a regular baseball's flight path but travel at a minimized distance when hit. The built-in holes minimize flight and distance. Sold in packs of 12, these batting practice balls are smaller than a regular baseball, closer to golf ball sized. The smaller size of the micro Crushers forces the eyes to concentrate closely on the ball for better contact. These Crushers help fine-tune swing accuracy, speed, and power without the need for batting screens during practice.
