Venus topples birthday girl Azarenka

STANFORD, United States, Aug 1 (AFP): Seven-time Grand Slam champion Venus Williams ousted fourth-seeded birthday girl Victoria Azarenka in straight sets Thursday to reach the quarter-finals of the WTA hardcourt tournament at Stanford.
The 6-4, 7-6 (7/1) triumph kept Williams on course for a possible semi-final showdown with her sister Serena, the world number one and top seed who will take on Ana Ivanovic in the quarter-finals Friday.
"Williams-Williams tomorrow, hopefully," Venus told the crowd at the campus of Stanford University, where she came out on top in a hard-fought, physical duel with Azarenka that lasted an hour and 42 minutes.
"It's never easy to play Victoria. We've always had extremely tough matches, so I expected that tonight as well," said Williams, who acknowledged that Azarenka may have been at a disadvantage after having a first-round bye.
That meant the match was the Belarussian's first since her second-round exit at Wimbledon.
It was a disappointing result on her 25th birthday for Azarenka, who came into the week ranked 10th in the world but needed to reach the semi-finals to stay in the top 10.
A left foot injury sidelined her for three months this year before she returned to action at the Wimbledon tuneup event at Eastbourne.
The former world number one, who owns two Australian Open titles, didn't go quietly.
She gamely fought off two match points in the 12th game of the second set to force the tiebreaker, but from there it was all Williams.
