bayoukid – You are absolutely correct, what is a pitching coach doing giving any instruction, other than pitching instruction, after all, all his job is to get his pitchers to get you out!
When the recruiting coach (also the pitching coach) came out to evaluate my son to get him to attend the school he is currently at, as he was hitting oppo shots in right center and over the right center fence, he stopped the session and said it looked like he was trying to force his shots to right field. He asked if he could just let loose and pull the ball, the next shot went way over the left center fence! He obviously knew what he was talking about.
What it is interesting he knew a lot about hitters and hiting and possibly how to pitch to them to get them out!
What is also interesting is, you are talking down a coach at a major university and you are a senior looking to play at a college, which may not have yet signed with a college.
Bottom line, I would suggest try to hit anyway a college coach (even a pitching coach), who may get you onto a roster, wants! It may be a test to see how coach able you are……
