Venus Williams squandered a lead in each set on Wednesday and lost her third-round match at the Olympic tennis tournament to No. 7-seeded Angelique Kerber of Germany, 7-6 (5), 7-6 (5).
Williams, seeking a record fourth gold medal in Olympic tennis, still has a shot in doubles with her sister Serena. They had a quarterfinal match scheduled later Wednesday at Wimbledon.
In the first set Williams failed to convert three set points, then blew a 5-1 lead in the tiebreaker. She was up 3-1 in the second set, but Kerber again charged back.
Kerber, a semifinalist at Wimbledon last month and at the U.S. Open last year, advanced to the quarterfinals against top-seeded Victoria Azarenka.
