Biggest Tennis Upsets since 2001!

Wimbledon has seen many spectacular tennis upsets over the years, most recently the sensational match between Lukas Rosol and Rafael Nadal, which saw the world number two crash out of this year's tournament.

This year Wimbledon will be the home to tennis for the London 2012 Olympics. Recent news that Nadal has pulled out of the Olympics means his name wouldn't feature on an updated list, but could Wimbledon see any Olympic tennis upsets?

Here are are top ten rankings for the biggest tennis upsets for both the ATP and WTA since 2001.

Playing a match over 5 sets always improves the favourites' chances, so it's no surprise to see a lot of grand slams and Davis cup matches on the ATP list. Nadal has the dubious honour of appearing twice, although it would be hard to blame him for losing either match given the remarkable form and hitting power demonstrated by his opponents.

While Nadal's stunning upset to Lukas Rosol at Wimbledon was well documented, Serena Williams' similarly shocking upset in the first round of the French open generated less press. 

The top half of the women's list features a few upsets of the Williams sisters, with Melanie South's 2006 victory over Schiavone making it to #3 on the list. With an extra round for even more upset possibilities, slams also feature heavily for the women, with only the US open failing to appear on either list. 

What will the Olympic tennis at Wimbledon bring we wonder?
