DG, I would say "go and go early"! We attended our son's first and second appearances as a pitcher during their spring trip. First outing was great; it was very emotional seeing him out there after all the work we had all done to get him there! The second outing was not so good; but we were glad to have seen it after he was redshirted that season and didn't play again in college (quit next season due to shoulder trouble and wanting to concentrate on becoming a physician).
He has now graduated, has no interest in medicine, and is working on getting into pro ball-you never know how things will play out!
