It sounds as though you are waiting on pitches and letting them get deeper into the strike zone. This should also indicate that you do not strike out much.
If that is the case, I would encourage you to just try to become more aggressive on pitches that are over the middle of the plate or middle in. See them sooner and recognize that pitch sooner and drive it up the middle or to your pull side.
Read the pitch and trust your hands.
The White Sox really enjoyed my son's ablility to hit behind runners. He continues to work on turning on that inside pitch more often, which is in his wheelhouse and should result in a HR.
