Defending champ Azarenka advances at Aussie Open
With her friend, American rapper Redfoo, watching in the stands and signing autographs, the top-ranked Azarenka stayed on track for a semifinal meeting with Serena Williams, who was scheduled to play the next match at Rod Laver Arena.
Azarenka needs to win the women's final on Jan. 26 to retain the No. 1 ranking she has held for much of the past year. She first earned the top ranking after winning last year's title here.
