May 18, 2009 -- Congratulations to Zack Johnson who won his second Valero Texas Open, this time by a sudden death playoff against James Driscoll. Aach had a week of impressive feats, including shooting a 60 in the second round, and being able to come back and win when it looked like his swing was faltering at times over the weekend. His ability to maintain his poise and hit clutch shots and putts have now vaulted him to the top of the FedExCup standings.

The thing that strikes me most about Zach's game is his consistency. His score can vary from time to time, but his game is rarely "off". And when the pressure is on, he has a consistent routine, consistent tempo and a consistent swing that can come up clutch for him when he needs it most. Sunday was a prime example.

Johnson's second shot on the first play-off hole was critical to his win. Driscoll was the hot golfer, having shot a 62 to force a playoff. But Johnson followed his plan and knew his fundamentals could pull him through -- and he was right. He hit a good second shot that left him a mere 10 feet from the hole. One birdie putt later, and Johnson has consecutive wins at La Cantera Golf Club.

What can you learn from Zach Johnson? Plenty. But this week, I'd like for you to focus on his posture. In particular, notice his good posture, keeping his address position the same from address to backswing, to impact position, and through the follow through before shifting all his weight to his left side. Zack also has a mirror image swing. The same length of his backswing mirrors the same length of his follow through. Zack was able to execute his shot by keeping his swing in tempo as well as keeping his spine angle constant.

Look at the black lines that mark Zach's swing from address to finish. They line up exactly! This is textbook.

By putting and keeping his body in consistent positions, optimized for solid ball striking, Johnson knows that his impact will not change dramatically from swing to swing. Wouldn't we all love to know that?!

The use of photography and high-speed video can help you attain a better posture for your swing. I would suggest you go find your local PGA Professional to help you find the best position for your golf swing and improve all aspects of your golf game.
