Wish more coaches had your mindset. Sometimes you get a girl you may not need to tinker with a swing and are able to focus on what areas she needs to improve.Yep- they're not all the same. I can say the same about DD#1 except she typically sees 5 or more pitches at bat, often has 2 strikes on her before hitting but typically has no more than 2 Ks per season.
From what you have described, your daughter is a more skilled hitter than most of the players I have worked with. If your DD had a coach that made her take until she had 1 or 2 strikes, she probably wouldn't like it any more than my DD likes it when she is told in no uncertain terms to go for the first pitch, period. Which brings us back to the earlier statement that you can't coach them all the same.
Based on your first comment -is your DD a pitcher?
That's the beauty of this game .. so much to learn.
