IMO , Kid threw a lot of pitches in HS. He needs recovery time. And he's going to need to be ready to compete in College in the fall. Shut. It. Down. No tournament. No throw for 6-8 weeks min. Then light catch once /twice a week ramping up to flat grounds before heading off to college.
Anything I write is just my opinion based on my experience. I'm the father of a 2016 that went into D-1 Ball after a heavy workload in HS and had major shoulder surgery 3-4 weeks into fall ball. He was out almost 18 months.
Take care of the arm.
