Hitting left handed it’s your shoulder where all your strength to lift the ball is used. If he doesn’t have any strength there he’s relegated to just being a slap hitter to get on base paths. Might not be a bad thing actually since he couldn’t do much of anything yesterday.What’s crazy is that it was his left shoulder but he’s a right handed pitcher so he could still dominate pitching just like how right elbow had surgery but still hit left
