Watch as Coach Ricky Watkins explains, and infielders demonstrate this 4 corners drill with different variations. The infielders start out focusing on being quick as they move the ball around. The 2nd phase is an inside turn followed by the glove side spin with an inside step. The focus is just playing catch but throwing the ball where you want to. The 3rd phase is throwing across then rotating positions after every 2 or 3 balls.
