The Jennie Finch Pitching Lane Pro is a great softball pitching aid. It comes with a regulation pitching rubber attached and is made from a spike-resistant artificial turf with a special rubberized backing that is guaranteed not to slip on gym floors. It allows pitcher"s to land on a consistent surface, reducing wear on the body. This mat helps pitchers comply with NCAA regulations (Rule 2.19) that restricts pitchers from pitching outside the 24" pitching rubber. The 6" barrier of white turf on either side of the rubber, in addition to the 2" inlaid white powerline allows for more precise training for pitchers of all ages. Each mat comes with a convenient carrying case.
