Venus and Serena Williams were both eliminated in the fourth round of Wimbledon on Monday, the first time in five years that neither sister will play in the quarterfinals at the All England Club.

Defending champion and four-time winner Serena was the first to go, beaten 6-3, 7-6 (6) by Marion Bartoli of France, cutting short the American's return to Grand Slam tennis after nearly a year out with serious health problems.

Older sister and five-time champion Venus was ousted 6-2, 6-3 by Tsvetana Pironkova — the exact same score of the Bulgarian's win in last year's quarterfinals.

Also knocked out was top-seeded Caroline Wozniacki, who fell 1-6, 7-6 (5), 7-5 to No. 24 Dominika Cibulkova in the Dane's latest failed attempt to win her first Grand Slam title.
