Serena Williams was leading and looked to be rolling onward in her quarter-final match with fellow American Sloane Stephens. Then in an instant, an injury started the downfall of Williams at the Australian Open.
Already hobbled with a sore ankle, Serena hurt her back while running down a drop shot. Williams’ back was tweaked enough to call an injury timeout.
Williams’ serve dropped to barely 90 miles per hour and Stephens took the second set. Amazingly, this was the first set that Williams had lost since the U.S. Open last September
The third set continued in the same manner as the 19 year old Stephens stayed with Williams and held on to win the third set and the match.
Sloane Stephens is the first American younger than Serena Williams to ever beat her. It will be the first Grand Slam semi-final appearance for the teenager from Florida.
Stephens will next face No. 1 seed Victoria Azarenka in the semi-finals of the Australian Open.
