Monday was a day that will best be remembered for the upsets that Wimbledon 2011 saw. The reputed likes of Woznicki, Serena and Venus were knocked out as the 'underdogs' reigned supreme. A look at the proceedings from Round 4.
Defending champion and four-time winner Serena was the first to go, beaten 6-3, 7-6 (6) by Marion Bartoli of France.
Bartoli served 10 aces in the match that lasted a little over two hours and the French player wrapped the match in her favour with rather effortless ease.
Sister Venus did not fare well either as she was knocked out by Bulgaria's Tsvetana Pironkova 2-6, 3-6.
