@ladiesman2157 this is late by 6 months but w/e, i cant help but comment. Of course curveball is different than fastball. Curveball is a breaking ball. I think you should read first whats a breaking ball, whats a fastball is before you say that learning a breaking ball might throw off a pitcher's pitching. I myself by no means an expert at baseball. But i know that a pitcher's cant survive on fastballs alone. You need breaking pitches, and amongst them curveball and slider are the most used and reliable. Sawa's lacking on true breaking ball which are curveball, slider, and its variations like slurve. And no, changeup is not a breaking ball, its an offspeed pitch. Splitter is a fastball, and sawa does not need that when he has a killer cutter
