This Hitting Area Chart download will show how one batter performs against all of your pitchers.  The red is for one pitcher, and thechart indicates that something she is doing against that hitter will have to be changed.  There are too many line drives against her.  Looking at her pitching chart will indicate where, in the strike zone, her power is.  And it looks like pitcher #1 keeps pitching to her power.

Pitcher #2 has a rise ball and the chart indicates that she keeps popping up against her.  It also shows that the batter is being fooled when she hits into short right field.

The same against pitcher #3.  Pitcher #3 is a little quicker and the batter has a hard time getting around on her.  Maybe inside pitches (to take advantage of her speed and the batters sluggishness against heat) would have a different chart result.
