My son didn't play college ball but he did play high school ball and at the same time he played in two other leagues.
Needless to say with just all the practices alone, he always had shoulder pain.
Every player had the necessary equipment in their bag, ie glove, bat, batting gloves, cleats and most important of all was a large bottle of Advil for the pain.
I bet there was more than just Advil taken for the pain and one of these days I will ask him about it.
He and at least four or five of his buddies have had shoulder surgery since they graduated from high school.
