Similar situation. Son also had a small slap tear. When he was a freshman in high school his coach had him catching 5 innings and then pitching the last 2 as a closer. Early spring of his sophomore year he started having shoulder pain. Saw the orthopedic surgeon who said it was not surgical and recommended PT. Did STRICT PT for 6 weeks to build up the muscle around the tear. He is now finishing up his sophomore year of college and hasn't had any issues (knock on wood) and is the starting catcher on a DI team. The surgeon and PT also told him he had to make a choice between pitching and catching. Too much wear on the shoulder to do both. Good luck!
