Hello everyone, hope your summers were good. After a short break, my son has decided to start pitching or at the very least throwing again. After reviewing these videos, what do you feel he should work on? I know glove side was an issue in the past, probably still is, but I was just wondering what else so we can start our routine on a good foot. Thanks to everyone in advance. Any positives would be appreciated as well, so I can leave that stuff alone.
P.S. These videos are from June, as July was his last month of pitching these should be current.
