The Evolution Of Tiger's Swing OR VIEW SWING SEQUENCE FRAME-BY-FRAME. Exclusive slow-motion video The Evolution Of Tiger's Swing April 2011 A Work In Progress: Watch a video progression of Tiger's swing from four stages of his career -- the early 1990s to the present (2011). See how his technique has changed with the influence of his different teachers: Rudy Duran, John Anselmo, Butch Harmon, Hank Haney and Sean Foley. For the April issue of Golf Digest on newsstands now, Jaime Diaz talked to the five instructors who have worked with Tiger Woods on his swing through the years. Their comments, and one from Jack Nicklaus: • Rudy Duran (started working with Woods when Tiger was 4): "Tiger's swing was a tool, like a chisel for a sculptor. But first he had the vision, and the tool carried that out. He didn't think about where his elbow was pointing when he used the chisel. He thought about the image he was seeing." • John Anselmo (began working with Woods when Tiger was 10): "I think the teachers after me have done a good job, but I don't think he needed much changing, to be honest. Sure, there was a looseness to his swing, but that was just because he hadn't filled out. I liked that freedom, that full release of his body. That was beautiful. He should hold onto that." • Butch Harmon (began working with Woods when Tiger was 17): "I thought he hit the ball plenty far enough, and that his strength was that he was one of the longest and most accurate drivers. When he drove the ball in the fairway, he was nearly unbeatable. That's what I kept trying to drive into him. But it didn't take. It's something about the ego of these long hitters. So we parted ways." • Hank Haney (officially began to work with Woods in 2004): "I think it's fair to say that Butch had a better body to work with than I did. With me, he started looking more like a linebacker than a golfer. ... Tiger Woods does what he wants to do. The other thing, in the last three years, he hasn't worked as hard. Without a doubt there has been a slip in his work ethic." • Sean Foley (began working with Woods in 2010): "What Tiger was doing wasn't efficient. He was losing tons of speed and power, some of the things that used to most separate him. And then he was getting more crooked. He couldn't hit the fairway because his alignments were not correct. Simple as that." • Jack Nicklaus: "When Tiger started out, there was nothing mechanical about him. Now he plays by mechanics, but I've noticed that when he starts making mistakes, he instinctively reverts back to feel. When he really has to win something, the touch and feel that he reverts to produces some unbelievable results. There are no mechanics at all when he's really under the gun. That's how he should play all the time."
