This event is run by Student Sports, which is a sports marketing firm.
The cost is $150 and there may be a video opportunity for a separate “discounted cost.” You will also receive a scorecard of ability from the MLB Scouts (which is always valuable for future marketing and personal knowledge).
It’s never a bad thing to be seen by scouts, if Johnny is a potential high draft (5-10). Generally, players at that level would/should have been seen if they are older.
Hint: This event is open to middle-schoolers as well. This sounds like a decently priced camp.
If I lived in PA, I would go to a Phillies Open Tryout and hope for a direct referral to the AC team , which is partially run by the Phillies.
Good Luck
