I could add variation to my game, but I'm going to win matches only when I hit those winners. I enjoy hitting the ball as hard as I can. I enjoy taking risks. And I believe you always have to take risks.

My injury happened during the match, ... I went to hit an overhand and it felt like I basically hyper-extended my back. I couldn't really move very well after that, and it felt very stiff.

He (Roche) worked on my overall game with a special emphasis on the serve and volley.

One win, and you're on top of the world. Lose in the first round of the next tournament: you're back to reality.

Tennis is like, it gives you a lot of chances, but if you don't take those chances, it takes a lot of chances away from you. It's just the scoring pattern. We cannot dwell over a loss or a win for very long. We have no time to celebrate; we have no time to dwell; we have to move on. Wake up the next day and try and win the match.

I've hit a couple game-winners, but nothing like that. It was a great one. It's going to last a long time in memory.
