One more thing I will add...at the plate she is very confident and very focused.
Confidence is always good. My DD tends to be confident regardless of how she's hitting. As far as focused? I guess, but just when I think she's figured it out, she'll have at-bats where she swings at pitches and lets others go that defy explanation.
My DD enjoys the talks about about how to approach an at-bat, but yet she tells me she does better when she doesn't think about anything - including the count, and what pitches she's looking for. That's a bit of a dilemma. I don't want her mind to be cluttered, but don't want it to be empty either, and sometimes it's obvious that it is for a particular AB. The mental game and coaching it is a challenge.
