Also, many current pros throw what are basically modified screwballs. Most circle changes have a screwball type action. Jake Peavy's fastball is thrown with heavy pronation, which is why it runs in on RH batters. So is Mariano Rivera's cutter than runs in on RH batters


Sorry Pain,

Have to disagree here! Rivera's cutter might run in on LHH. I would bet Peavey is throwing a 2-seamer which commonly runs in from a RHP to RHH. Never have I heard of these being compared to a screwball. But I guess the circle change and 2-seamer do have screw ball path at times.

micmeister,

Thanks for the compliment. We have a lot of people who work at Perfect Game. Like everything else we are all different. But there are plenty of real good baseball people on our side.
