Re: WWW The "Disrespectful QF": Serena vs. Sloane?
When Serena says she has nothing to lose, it is generally when she is playing a higher ranked opponent. I believe she said it this time because she only had round 4 points to defend, and now she is already in the quarters.
As for the match-up, who knows what Sloane's career will be like. She does push too much now, but she has a forehand and big 1st serve that she keeps in her back pocket. One day she may learn to use her weapons more. If so, she could challenge for big titles. She is not doing that consistently yet though.
For this match? Serena in two straightforward sets. But, this could be her most challenging match in the tournament so far.
