As a PO my kid traveled out of state for a showcase tourney and waited all week for his start only to choke.
His turfs were slipping on the mound. His velo sucked. His location sucked.
I don't think he completed 2 innings before he got the hook.
Several coaches - who I believe were there looking at him - shut the door on him that day.
Huge waste of time money and effort.
Life goes on.
He had other, better outings elsewhere. Other schools who were watching him came to see him pitch at his high school games. Some were in communication with his pitching coach.
Some were at the playoff game where his threw a complete game and shined.
Things will work out.
Keep it positive with your son. Try to help him be confident and not overthink.
Tell him you both know he's a stud. He just needs to show them he's a stud.
