10th seeds Bethanie Mattek-Sands and Nadia Petrova were upset today in their third round match at Wimbledon. Defeating them 6-4, 7-5 were Alisa Kleybanova and Ekaterina Makarova.
Nuria Llagostera Vives and Maria Jose Martinez Sanchez advanced to the fourth round when their opponents, Victoria Azarenka and Elena Vesnina, gave them a walkover because of Vesnina's heat illness.
And Zheng Jie and Yan Zi--while they no longer enjoy the very high ranking they used to have, because of injury issues--nevertheless were seeded 13th at Wimbledon. Today, though, they failed to win one game against 4th seeds Venus and Serena Williams.
In mixed doubles, 3rd seeds Marcin Matkowsky and Lisa Raymond were upset by 15th seeds Iveta Benesova and Lukas Dlouhy. Top seeds Cara Black and Leander Paes defeated 13th seeds and 2009 Australian Open champions Sania Mirza and Mahesh Bhupati.
