Zvonareva was the third Russian woman to play the Wimbledon after Olga Morozova (1974 runner-up) and Maria Sharapova (2004 winner). She was the second lowest-ranked finalist behind Venus, who stood 31st in 2007.

The losing finalist will improve her current ranking, with an estimated placing of 10th when the WTA list is issued Monday.
