LONDON (AP) - Serena Williams pulled out of her Wimbledon doubles match with sister Venus after only three games Tuesday.
Serena, who lost in singles Saturday, was checked by medical staff before the doubles match even began. Sitting in her sideline chair, Serena covered her face with her hands.
Eventually, the match against Kristina Barrois and Stefanie Voegele began. With Serena serving in the third game, she was broken at love, hitting faults that bounced before reaching the net.
At love-40, chair umpire Kader Nouni took the unusual step of climbing down and walking over to speak to Serena. She then served another double-fault to trail 3-0.
Serena and Venus walked to the sideline holding hands, and Nouni announced to the crowd: "Ladies and gentlemen, unfortunately, Miss Williams has to retire."
