WIMBLEDON, England (AP) - Venus and Serena Williams were so eager to reach the Olympics semifinals they collided and tumbled to the grass chasing a shot Thursday.
They won the point and the match, beating No. 2-seeded Sara Errani and Roberta Vinci of Italy 6-1, 6-1.
Serena was at the net and prepared to hit a shot when Venus came forward to take it.
"She said 'Mine,' and she said 'Mine' again," Serena said. "I was like, 'I don't know why I'm not stopping.'"
"I really didn't see what happened," Venus said. "But Serena told me we won the point after."
The sisters, who have yet to lose a set through three rounds, seek their third gold medal in doubles. Serena is also into the semifinals in singles.
Venus seeks a record fourth gold medal in tennis.
"We have a chance to win a medal," Serena said. "That's what it's all about."
