Watch as Coach Paige Cassady explains that she wants all the pitches to look like strikes within 15 feet of a hitter before falling off in different directions. The pitcher's Tunneling Warm-Up involves throwing every pitch in a spin progression starting with a baseball, switching to an 11-inch ball, 12-inch, 14-inch, and back to a 12-inch ball. The goal is to throw the ball straight, produce as much spin as possible, and have consistency in the wrist no matter what size ball is being thrown.
