Serena Williams Loses To 19 Year-Old Sloane Stephens! Serena Williams has been ousted from the 2013 Australian Open by 19-year-old Sloane Stephens. Stephens outplayed the tennis great, whose movement and serves had been slowed by a back injury, and beat the 15-time Grand Slam champion 3-6, 7-5, 6-4. It was Williams’ first loss since Aug. 17, and her first defeat at a Grand Slam tournament since last year’s French Open.
