Makes perfect sense she throws the lh drop curve to the rh hitter and the straight drop to the lh hitter. If I was calling pitches and IF she could make the ball break down and in to the lh hitter the way she can to the rh hitter, I'd never call a straight drop. This is what I'm talking about when I say the direction of drop compared to the ground is unimportant. The direction of drop in relation to the swing plane is a big deal imo.
