It's gotta be tough, im sure you want to impress him and get an offer at some point. Alot really good advice here so far. I can tell you a times, when my son knew guys were watching, he got a little amped up and while his velo was very good, his location wasnt. Fortunately he was seen quite a bit across many many months and that worked out. Be you and focus on your game and your job. Trust your stuff, it's what got you this far. Good luck!
