When a tennis player scores a career-high win, the question always arises whether this is a one-time event or the beginning of a new era of success. That question is now being asked of Aussie Sam Stosur, who has been ranked #1 in the world in doubles but never reached higher than #27 on the singles board. Stosur is pictured here after knocking out Dementieva to reach the fourth round, where she will face Razzano (the single one of the potential WSB sleepers who has made it this far).
