MELBOURNE, Australia

Serena Williams is out of the Australian Open after losing her quarterfinal match 3-6, 7-5, 6-4 to 19-year-old American Sloane Stephens.

Williams appeared to hurt her lower back while attempting to pull up short of the net during the eighth game of the second set. She called for a trainer after the ninth game with the score 5-4 and on serve.

Stephens won the second set when Williams, serving slower than usual, was broken. Williams also had her service broken in the final game of the match.

At 2-1 and on the way to a changeover in the third set, Williams smashed her racket angrily on the court then threw it toward her chair. Stephens will play defending champion Victoria Azarenka in the semifinals.

Williams had lost only one match since a first-round exit at the French Open in a streak that included back-to-back major titles at Wimbledon and the U.S. Open as well as the Olympic gold medal and season-sending WTA Championship.

She beat Azarenka all five times they played last year, and was 11-1 in career head-to-heads against the 23-year-old Belarusian.

Azarenka’s American rapper friend, Redfoo, returned from a concert in Malaysia to attend Wednesday’s quarterfinal match.

Wearing a red sleeveless T-shirt that read “Keep Calm and Bring Out the Bottles,” the name of his next single, Redfoo stood, clapped and yelled “Come on, Vika!” during the tight first set.

In the men’s quarterfinals, 17-time major winner Roger Federer was playing No. 7 Jo-Wilfried Tsonga in a night match and U.S. Open champion Andy Murray was to meet Jeremy Chardy of France.

Novak Djokovic is already through the semifinals after his 6-1, 4-6, 6-1, 6-4 win over fifth-seeded Tomas Berdych on Tuesday night.

The 2-hour, 31-minute victory took exactly half the time of his five-set, fourth-round win two nights previously against Stanislas Wawrinka.

“It was a great performance. I was hoping to have a shorter match ... just not to go over 5 hours,” Djokovic said, in a comparatively subdued mood Tuesday after a considerably more routine victory. “It’s always going to be tough against Tomas; he’s an established player. He has a big game, big serve. He can compete against anyone on any surface.”

In the semifinals, Djokovic will meet No. 4-seeded David Ferrer.
