Simply stated on low pitches......Do not lock the front leg, the body needs to work up and down, not forward or back. If you lock your front leg on a low pitch you create angles and great pitchers will own that hitter. Try doing low tee work and see what kind of ball flight you generate with a locked front side (just check out the angle you create with the bat), you know spin and trajectory. Jack, as I've said, does a good job and I love his work, but I would not teach it that way....with all do respect. I have a saying and it goes........"Never judge those for who's shoes I have not walked" I respect Jack and believe he thinks he's right........This works for me!
