I spent a lot of time with my kids teaching them how to hit at young ages and I run hitting clinics for my girls now and I'm astounded at the difference between girls who are in Travel and are hitting all the time and my kids who only lightly did travel and the amount of contact my kids make vs these supposed selected players. My kids were never power hitters (indeed my daughter has noodle arms) but she can put a ball in play on any pitch that is within 5-6" of the strike zone.
Was that taught or was it just reps?
