I am sure all schools are different. PC at son's school (LSU) has no preference. Our Saturday starter pitches purely from the stretch. He was mainly a bullpen guy his first two years. I remember him pitching out of the windup, but at some point last year he went strictly to the stretch all the time. I can remember the TV guys specifically pointing this out. I just think he feels it simplifies his motion. Has zero affect on his velocity. Our Friday night guy is sort of a modified windup / stretch motion. Has a very small step. My son is pretty similar to this. He does throw from the windup, but has a very small step. Not sure this helps you, but to Buckeye's point, I think each pitcher is different. Like I said, the one starter we have that pitches exclusively from the stretch throws 92-94 which is where he was last year when pitching from the windup.
