I'm not a family counsellor, but here's what they say in The Complete Book of Hitting Faults and Fixes on hitching. First they say that hitching isn't necessarily bad, as long as you complete it before get into the launch position. Then they say that curing a hitch is one of the easier corrections to make. Their correction drill is called the Walk-Up Tee Drill. "Take 3 or 4 steps back away from your stance position (as if you were standing deep deep in the batters box). Take slow steps up to the tee. Stride and swing in one continuos motion. Your natural instincts will be to push your hands back to your rear shoulder-the power position-before swinging. Repeat until the hand movement becomes habit." Hope that helps.
