I know they test hand strength (grip) at camps. The best I can tell is they use it as a general indication of overall strength. I read that somewhere. On a scale from 1 to 10, how important is hand strength? How do you test it at home (DYI)? Should I have my DD who is smaller in stature (5'0' and 91 lbs.) work on her hand strength? She has a good fundamental swing. Bats in the 2 hole and leads her team in OBP (.490). She has great eye hand coordination. Very few extra base hits. Is hand strength the missing link?
