A baseball pitcher is automatically going to have vertical movement because they pitch from an elevated mound not flat ground. Regardless of what pitch they throw, the ball has to travel downward for it to be a strike. How far down it goes can vary and is reflected on where it ends up in the strikezone, if at all.In baseball the slider, cutter and sweeper all have substantial horizontal movement and can be an important part of any pitcher's arsenal (Mariano Rivera: just a fastball and a cutter). So horizontally breaking pitches can be effective. But a crappy slider, cutter or sweeper can get crushed so it is not so much the nature of the pitch itself but the quality of it that matters, and in softball I don't see a lot of quality curve balls. That could be for several reasons, it is taught poorly, or maybe the size and weight of the ball make it a difficult pitch to learn and throw with the correct spin.
