Cross-Handed chipping looks a little quirky and will definitely feel strange at first, but it’s got some obvious benefits. As explained by Fitzpatrick's short-game coach Pete Cowen.
“Cack-handed swings,” Cowen calls the drill. “It teaches a full release of the club by forcing the body to rotate through the shot.”
And that’s the key to this drill. With a left-hand low, or “cack-handed” swing, you’ll hook the ball if you release the club too early and shank it if you release the club too late. Your goal is to hit the ball straight, which you can only accomplish if you rotate through the shot.
