To piggy back on what Corlay said. Most girls swing and miss under a pitch. I don't know why, but most misses are under, not over. A bullet spin pitch drops less so that under miss is more frequent. When a pitcher first learns down spin, chances are it is not very high RPS so it helps the batter out by dropping a little and helping contact. With time, they can increase their spin rate and become great groundball pitchers that rarely give up liners or driven fly balls compared to their bullet spinning counterparts, but during that development of getting spin to the high teens or low 20s they get hit pretty well in my experience. In the long run it is well worth it because as hitter develop, that bullet spin ball becomes a HR ball. I know Cat has said her FB is a bullet spin, but i don't think she throws it often if ever. She throws bananas up down and sideways so why would she?
