Here's my take: When the pitch is outside the body, to the catcher's arm side, you can just extend through your tricep💪 But if you extend your tricep on the catcher's glove side, he will take it away from his body.😬 The only way to get the ball back up to the center/mask on the catchers glove side is through a bent arm and rotation.👊 Dingler does a crazy job of showing just that on this pitch with the bent arm🤯 #baseball #catchers #catchingmadesimple
