US Open Champ Samantha Stosur looked not so champion-esque in her second match at the Women’s Tennis Association’s championships.

After her win against Maria Sharipova, Stosur lost against Belarusian Victoria Azarenka. Even with this loss, Stosur still has a chance to make it into the semi-finals with a win over Li Na of China.

Though this loss is a rough one, it comes on the heels of the win against Sharipova, who Stosur has failed to beat nine out of the past ten times.

With Stosur’s 1-1 record going into the last match of the round-robin portion of the tournament, one has to wonder which match will stick in her brain. Will she use her excitement with her victory to propel her to another? Or will her defeat hold her back in another match?
