If the lefties are pulling off toward first, low and away is good. Rise in and rise curve and curve on the inside black or more at the knees or hands is good. If you had a drop curve, that works too. Cutter in might work. I wouldn't throw the change to a power slapper unless her run up was crazy early and fast. If I REALLY love my very quick defense, I don't mind throwing the change to pure slappers who aren't crazy fast.
