I used to turn my shoulders pretty level, which a lot of golfers think is correct. But that made my swing too shallow coming into impact, so my contact was picky, especially off the turf.

I'm John McEnroe-like. I'm coming forward every opportunity I get. My wingspan covers some ground at the net. My serve is OK. I can move it around enough. My groundstrokes are good enough to hang in a rally with a good player. But generally, my goal is to put away a point quickly.

I almost didn't turn pro at all. I was tempted to be a career amateur. I worked as an investment banker for nine months after I got out of school, and the money was fantastic and promised to get even more lucrative.

I went seven years between 2002 and 2009 without winning. Then I did win in '09.
