I am looking forward to getting healthy and defending my year-end No.1 ranking at the WTA Championships in Los Angeles next week,

It's not a mission of mine to end the year No.1. I know if I win everything I have a very good chance, but I just want to focus on the matches I have to win and the tournaments that I'm committed to for the remainder of this year. Of course I'd take another Grand Slam title over the No.1 ranking any day, but I am proud of the fact that I'll probably finish another season at least in the Top Three. That's no mean feat.

Times are very important (this year) because there are no championships.

Didn't know that. Not important, ... We'll settle it once and for all at the end of the year.
