Reliever for the Oakland A's Lou Trivino talks about his transformation from an 89 mph starter into a 99 mph reliever, how adding a coil to his delivery allowed him to create more tension in his throwing motion and find untapped potential in his arm, how developing a cutter changed his game, how throwing a good cutter is less about grip and more about approach behind the pitch and feel for the ball out of the hand, and how he prepares for the demands of throwing daily at the big league level.
