do you use the "high tee" drill to develop "backspin"? Backspin creates an extra 30' carry on the ball. Whether you start with the hands "high" or low does not make a different.
The hands can be elevated to be on top and drive thru and then up. Use the full BP cage for best learning. Concentrate on the "red seams" when hitting. Always practice with wood and listen for the sound of impact "bat to ball",
PS: last night watched Clint Eastwood "Trouble with the Curve" [Classic baseball movie]
