Sloane Stephens upsets Serena Williams

Sloane Stephens, a 19-year-old American who has the eyes to be a champion and the stamina to live up to it, was paired against Serena Williams, possibly the best American women's tennis player to ever hit a yellow ball on a court that has seen five trophy ceremonies set for Serena.

The match ended with Stephens upsetting the elder Williams 3-6, 7-5, 6-4, but there was plenty of action in between those numbers.
