Roger Federer, who has a record 17 Grand Slam titles in 24 finals, is the second seed ahead of US Open champ Andy Murray and Spain’s David Ferrer. Nadal will miss the event as he is suffering from a stomach virus.

Defending women’s singles champion Azarenka is seeded ahead of last year’s finalist, Russian Maria Sharapova, five-time winner Serena Williams and Poland's Wimbledon finalist Agnieszka Radwanska.
