MELBOURNE, Australia -- With her most famous fan sitting in the crowd wearing a shirt reminding her to keep calm, defending champion Victoria Azarenka overcame some early jitters to beat Svetlana Kuznetsova 7-5, 6-1 on Wednesday and advance to the Australian Open semifinals.

After dropping serve in a long fourth game which went to deuce 10 times, Azarenka recovered to dominate the rest of the match against Kuznetsova, a two-time major winner who was floating dangerously in the draw with a No. 75 ranking as she recovers from a knee injury.  
Azarenka will meet the winner of Wednesday's later quarterfinal between Serena Williams and 19-year-old American Sloane Stephens. Williams has 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 is 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.  
Asked if it helped to have her No. 1 fan wearing a keep calm logo, Azarenka said "I was looking more at the part that says `Bring out the bottles."  
Of her game, she added, "I'm just glad I could produce my good tennis when it was needed."
