Posture and alignment

"I really work hard on the fundamentals, always checking my posture, my stance and my grip. They are so important, and this is where I see the majority of problems in amateurs. If you don't address the ball right, lots of swing faults stem from there. I mean, if you slice the ball you start aiming further left to allow for that, which just makes your slice worse."

 

"I think grip and posture are the two most important things to learn before you can start playing better golf, because you can build a swing from there. If you have bad basics, though, it's very hard to develop a good swing. It just doesn't happen."
