Li Na (on losing her rhythm in the second half of the match): I was feeling maybe start the match too exciting. So when after one half set I was feeling no more energy left. Yeah. And also, I think it's a tough tournament, because I was play five days in a row. Every opponent top 8, so, you know, never have an easy match in this tournament.

Serena Williams (on playing 15 tournaments I 2013 ): I played you said 15 tournaments? That's really not a lot, but, you know, looking it's really not a tremendous amount of tournaments. It's definitely I think the results which was more consistent, so if I could play the same amount of tournaments and not do any more, I'm okay with that. But 15 I think is a bare minimum, or it's pretty low. Maybe I will do 14 next year or 13. Yeah. But definitely not more. Maybe one or two less.
