Serena Williams arrived at the Western & Southern Open with an Olympic gold medal and a chance to win another tournament she had never won before.
Really, Serena, you haven't won here before.
During a pre-tournament news conference on Monday, Williams was confused about whether she had taken a title in Cincinnati.
''I did win this tournament, didn't I?'' she said during a press conference. ''Maybe I didn't. I can't keep up. I don't think I did. OK. Whoops.''
She has played the Cincinnati tournament three times and her best showing was a semifinal loss in 2006.
Williams followed-up her Wimbledon championship in July by overwhelming Maria Sharapova, 6-0, 6-1 to win the Olympic singles title.
The 31-year-old, who's ranked No. 4 in the world and is seeded second at the $5.7 million event, spent a week training in Paris before arriving in Cincinnati. She still was basking in the glow of winning both the singles and, with her sister Venus, the Olympics doubles championship.
