Learn from a LeftyMickelson's swing is a model for all playersPeople always ask me if I have to make adjustments when working with Phil because he swings from the left side. Actually, the opposite is true -- I'll turn other players' swings over to compare them to Phil's because he's in such good positions. Things like his grip might look exaggerated to the right-hander, but that's only because you aren't used to seeing it. Phil's swing is textbook -- just flipped.The one thing I've always loved is how free-flowing Phil is through the ball. He has tremendous, smooth acceleration in his swing, something he's always had. It's because he's mastered the three important power-producing principles. Look at the second and third pictures on the top row below and you can see the first one: Phil has a very wide arc. His hands and the club are away from his body, not cramped too close.Second, he makes a complete wrist cock in the backswing. That's a swing lever that many average players don't take advantage of. Third, he really moves his body well during his swing. He makes a great shoulder turn on the backswing, and swings his rear shoulder (left for him, right for right-handers) down and through the ball. That great body motion is what makes his swing so free-flowing and fast.But what if you aren't flexible enough to turn your shoulders like Phil? Don't worry -- not many people are. You can still make a bigger shoulder turn. Start by closing your stance slightly. This promotes more hip turn, which allows the shoulders to turn more as well.Just be sure to turn your right hip away from the target line when you shift your weight on the backswing. Many players slide the hips down the target line instead. That locks you up, and you can't generate any speed.Combine that increased hip and shoulder turn with a wider arc and full wrist cock at the top of the backswing, and you'll be hitting your longest drives.Rick Smith is based at Treetops Resort in Gaylord, Mich., and Tiburón in Naples.
