My initial dream was to be a baseball player, ... I remember throwing a baseball at 2-years-old in the house. My dreams of playing tennis just kept changing. It's been a remarkable road.

I knew I was the second-best tennis player in the state of Florida and No. 8 in the United States of America when I was 12 years old and I couldn't tell you what I was in baseball, but I liked my chances in tennis of getting a scholarship to college.

The reason I didn't take the baseball route is because they don't have rankings for baseball players.

If they had rankings in baseball, maybe I would have been able to do the math and figure out my chances of being a professional baseball player versus a tennis player. But that was the decision-maker for me, I just thought I was better in tennis.
