Dusty Baker wrote " set up with level elbows and form the box". What he did not write was when the front toe touches that elbow should be higher and around behind you.
Many players will not load properly and keep their shoulders back going into toe touch. A fix for many is to get the elbow higher and behind the body more in the waiting position. This preloaded scap muscle and high elbow position does two things that are very important.
1. Keeps the shoulders "in' until the hips begin to rotate
2. THe higher elbow position insures that the hands lead the elbow to the slot.

It helps many things that you would not readily expect like lunging, disconnecting and pulling too many pitches. Nomar, Griffey and many other employ this rear side mechanic.
The ole" get your elbow up" was not a bad cue if you get it up and around. It is not a linear cue that is followed by " and swing level". It can really help rotational mechanics.
