The camera helped Warren win a long-standing argument he’d had with his son. Trevor believed pitchers decided when to release pitches, but Warren didn’t believe this was a conscious action. The camera confirmed his suspicion. It showed that pitchers don’t release the ball by moving their fingers. Rather, the hand accelerates the ball linearly, forcing the fingers to extend or open. This led to a key finding that would shape Trevor’s future approach to pitch design: grips were best thought of as escape routes for the ball.
