Champro Training Baseballs, Set of 6 (Red/Maroon/Green/Yellow/Blue/Black, 9 Inch)

WEIGHTED TRAINING SET: The CHAMPRO Weighted Baseball Training Set provides a way for players to improve their in-game performance. Many players agree that training with weighted balls can increase their velocity when playing with a regulation game ball. STRENGTH BUILDER: Train with the progressively heavier balls in this set to work on building arm strength and throwing velocity. PITCHER TRAINING: CHAMPRO’s weighted training baseballs have stripe patterns that allow pitchers to monitor the pitch rotation, helping them develop their skill set. DURABLE CONSTRUCTION: These balls have raised seams and full-grain leather covers that are made to last. INCLUDES: These sets come with 6 progressively heavier balls. Choose between a set of one 3, 4, 6, 7, 9, and 11 oz ball and a set of one 7, 8, 9, 10, 11, and 12 oz ball. Each includes a training program to help athletes get started right away.
