In other matches, defending champion and fifth seed Chanelle Scheepers of South Africa completed a 6-4, 6-1 victory over Bojana Jovanovski of Serbia, while Urszula Radwanska of Poland defeated Mandy Minella of Luxembourg 6-2, 6-3.

Zvonareva, Pennetta pull out
Last year’s runner-up Vera Zvonareva of Russia and Flavia Pennetta of Italy pulled out of the Pan Pacific Open tennis tournament that gets under way this weekend, organizers said Wednesday.
Zvonareva, who captured her second Grand Slam doubles title at the Australian Open in January, is suffering from a viral disease, while Pennetta has a right wrist injury, the organizers said.
Aleksandra Wozniak of Canada and Vania King of the US moved up to the main draw, they said.
The tournament will be led by world No. 1 Victoria Azarenka of Belarus and former world No. 1 Maria Sharapova of Russia.
Federer could play Berdych
The first round of the 2013 Davis Cup could feature a matchup between Roger Federer and Tomas Berdych, the man who beat him in the quarterfinals of the US Open two weeks ago.
Switzerland was paired against the Czech Republic in Wednesday’s draw for the opening round of the World Group, setting up a potential head-to-head between two of the top players in the game.
The top-ranked Federer has a career 11-5 record against Berdych, but the No. 6 Czech defeated him in four sets at the US Open. Berdych also beat Federer in the quarterfinals at Wimbledon in 2010 and at the 2004 Athens Olympics.
Switzerland will be at home for the Feb. 1-3 series. Federer does not always play in the early rounds of the Davis Cup, and his plans for 2013 are uncertain. In other matches, Spain will travel to Canada, the United States will be at home against Brazil, and Argentina will host Germany.
It’s also France vs. Israel, Kazakhstan vs. Austria, Italy vs. Croatia and Belgium vs. Serbia. — Agencies
