Guys...help me out here.
I coach/teach a 15yo pitcher who, last night, presented a situation which I have never experienced before. While his 4-seamer topped at 78mph, his 2-seamer (cross seams) topped at 79mph. From a pure physics standpoint, that shouldn't happen though I simply chalked it up to grip comfort. However, we then moved his fingers inside the seams which should have produced less spin and, thus, less velocity. To my amazement, he topped at 80mph with this grip.
Now, I've been at this a long time and simply cannot arrive at any logical conclusion for such anomalous results. While I have a pretty solid foundation in physics and biomechanics, I'm absolutely baffled by this. Has anyone else ever experienced a similar situation? Your input would be appreciated.
