My son is a LHP. I was watching some MLB feed on twitter that contradicted what I think I had heard about change ups to same side hitters. In general, I’m pretty sure that my son’s coaches rarely call CUs against lefty batters (LHB). I realize a great curve ball is probably a better pitch against LHBs from a LHP, but why is a change up not a go to pitch against an arm side hitter? Same seems to be ingrained in my son that he doesn’t throw sinkers to LHBs either. I think the movement inside would be devastating or at least a foul ball like a cutter from a LHP to a righty batter. Maybe I heard wrong? Curious what your experience is.
edit: let me just reassure you that I don’t call my son’s pitches and I don’t really talk to him about his pitch strategy except to congratulate him after a game on doing well. Just curiosity here about this.
