I wouldn't worry about where she is compared to teammates. If you're going to use the stats for something, use them to judge how she is doing. You already know she needs to get better. Use your stats to judge how she's improving. Does it really matter is she has the 8th or 9th best BA when she has lots of room to improve?
No, just want to make sure she is not in over her head and/or dragging the team down.
