Each pitcher has her own comfort zone. The mental component of pitching should not be overlooked, as far as routines are concerned. When taking a free throw in basketball, dribbling the ball some number of times at the foul line does nothing to benefit the shot, yet even the best foul shooters generally do it.
Heee. Funny you should say that. I've been encourged to lose the high wind up because of these issues (no shoulder pain, just worries about tiring me out) So I've been doing a small wind up. Only problem? For some unknown reason, when doing this short wind up my front foot comes up. I don't know why, it just does. Making me illegeal as all get out. I'm using Xmas holidays (my whole week and a half!) to work on this with my dad. I need a smaller wind up but I need to be legal too
