For me, 2013 was a breakthrough year but also an eye-opener. I won my second PGA Tour event, the Greenbrier Classic, but I had some spurts where I didn't play well. And believe me, I don't like those times. What I learned was that if I want to get to the next level, my ball-striking has to improve. With help from my swing coach, Jorge Parada, I started working on changes to get me hitting it higher and farther off the tee. Tying for second at the Masters was a big confidence boost, but this is still a period of change for me. I think the things I'm working on can help your driving, too.
