Hey all ..Got a question.
My son a rising college junior went to local
MLB tryouts. He is a pitcher. At both tryouts he made all the cuts and stayed until the end.
My question is this..When he pitched a "bullpen" he threw from straight ground in the first round of cuts.
Today he threw from a training type of artificial mound that was very bouncy and had no "rubber" to push off from.
Would his velocity be more from a viable mound? Do they, (the scouts) know this?
Another question. I noticed that at some showcases they have the radar gun behind him. I also noticed that at the MLB tryouts they are behind the backstop? Does this matter as far as velocity?

Velocity should be the same whether measured from in front or behind the pitcher as long as they're in a straight line with the pitcher and catcher.
