Djokovic, Federer, Azarenka take Open spotlight
World number one Novak Djokovic and 17-time Grand Slam champion Roger Federer are Tuesday's top attractions at the US Open with big servers John Isner and Milos Raonic also on the schedule.
Djokovic, a six-time Grand Slam champion who captured his fourth Australian Open crown earlier this year, launches his quest for a fourth consecutive trip to the US Open final when he faces Lithuanian Ricardas Berankis in the first night match at Arthur Ashe Stadium.
The Serbian star will be followed into the main stadium by two-time Australian Open champion Victoria Azarenka of Belarus, who will meet Germany's Dinah Pfizenmaier in a first-round matchup.
And seventh-seeded Swiss star Federer, at his lowest spot in the US Open order since 2002, will face Slovenia's Grega Zemlja in the last afternoon match at Arthur Ashe in a match that was postponed from Monday due to rain.
Canadian 10th seed Raonic opens against Italy's Thomas Fabbiano at Louis Armstrong Stadium while Isner, the top US hope at the 13th seed, will meet Italy's Filippo Volandri on the Grandstand.
Czech fifth seed Tomas Berdych, on a quarter-final collision course with British defending champion Andy Murray, faces Italy's Paolo Lorenzi in their opener.
Czech seventh seed Petra Kvitova opens at Ashe with a morning match against Japan's Misaki Doi while Denmark's sixth-seeded Caroline Wozniacki, a 2011 US Open semi-finalist who was ousted last year in the first round, follows against China's Duan Ying-Ying.
Italian fourth seed Sara Errani, a US Open semi-finalist last year, will meet Australian lucky loser Olivia Rogowska.
Another Aussie, 2011 US Open winner Samantha Stosur, launches her title bid against Victoria Duval.
Stosur split with her long-time coach David Taylor after a WTA title at Carlsbad, her first crown since her Grand Slam breakthrough two years ago on the Flushing Meadows hardcourts.
