Many people in baseball have observed that pitchers often generate similar ball speeds from the windup and stretch, so that there must be no advantage. However, I know of no biomechanical study that compares the kinematics and kinetics between the two methods to scientifically answer this question. Such a study would be helpful.

Hey John we did compare the wind-up and stretch in some of the pitchers that we have tested. In general, we found no variation in pitch speed, and kinematic and kinetic variables. We did not write up our findings but we will soon.
