Over a three-week span on tour in August that included the WGC-Bridgestone Invitational, the PGA Championship and The Barclays—three tough courses—Hunter Mahan hit 78.7 percent of the greens in regulation. That equates to four more greens per round than the field average in those events. That's a big deal.
One thing that made Hunter so accurate was that he has flexion in his left wrist at impact (pictured below). Flexion means bending the wrist so the palm moves closer to the forearm. That's the magic move that puts the clubface in position to compress the ball and control the trajectory and distance of the shot.
To incorporate this into your swing, start practicing it on 50-yard wedge shots until the move feels routine. Then you're ready to take it on the course and start peppering the greens.
