- London Olympics 2012
Murray seeded third for London 2012
The British No. 1 believes the Olympics offers the opportunity to put the disappointment of failing to land his first grand slam title at Wimbledon firmly behind him.
Murray, who endured heartache at the All England Club with defeat to Roger Federer, remains fourth in the ATP rankings but will be seeded third owing to Nadal's decision to pull out with a knee injury, while Federer is the top seed for the tournament.
Murray, who would have been on the opposite side of the draw to world No. 3 Nadal, is still likely to face both Novak Djokovic and Federer to be in with a chance of winning Olympic gold at SW19.
Victoria Azarenka will be the No. 1 seed in the women's draw, with Wimbledon champion Serena Williams fourth.
In the latest WTA rankings, British No. 1 Heather Watson continues to improve her standing, reaching a career high 67, while Elena Baltacha has dropped out of the world's top 100. Meanwhile, Juan Monaco, a winner in Hamburg last week, climbs into the world's top 10 for the first time.
