Struggling and sore, Serena almost happy to head home

Serena Williams of the US slides during her quarterfinal against compatriot Sloane Stephens at the Australian Open on Wednesday. Williams was defeated 3-6, 7-5, 6-4, thanks in part to a badly swollen ankle and back spasms. "Oh my gosh, it's been a little difficult," the 15-time Grand Slam champion said later.
