Thanks craftyshortstop.....great info from someone who is currently watching heir son play D3 baseball. He still has two more years left, so we'll see where his velo ends up but I'm assuming if he get into the low 80s, he may get some looks being a lefty and with his grades.
if not...im sure he'll go to a good University, join a fraternity and have just as good a time. 
....remembering that most of these HS and college players will never make a living playing baseball. Good luck to your so this season!
