TORONTO (AP) - Dinara Safina is out of the Rogers Cup.
The No. 1-ranked Russian fell 3-6, 6-2, 6-4 to Aravane Rezai of France in a second-round match Wednesday at the $2 million WTA Tour event.
Safina's loss comes one day after No. 3 seed Venus Williams was upset by Ukraine's Kateryna Bondarenko.
Safina opened strong, but fell apart in the second set with six double faults and winning fewer than half of her points on serve. Safina finished with 17 double faults.
The 23-year-old was broken three straight times in the third and deciding set, slamming her racket to the ground after the final point.
Safina fought her emotions while trying to explain how the match got away.
"It's my brain," said Safina, who lost an opening match for the first time since February. "I know exactly what I have to do, but if I'm not using my brain, I'm not doing the things my coach is telling me. ... (I'm) too disappointed with myself."
The tournament lost another high seed when No. 8 Caroline Wozniacki fell 7-5, 6-3 to China's Zheng Jie. Wozniacki was broken seven times in the match, and saved just one of four break points in the second set.
No. 12 Flavia Pennetta of Italy is also out after a 6-3, 6-1 loss to Virginie Razzano of France.
Seeded players to advance to round three Wednesday included No. 4 Elena Dementieva of Russia, who cruised past Japan's Ai Sugiyama 6-3, 6-2, and No. 7 Vera Zvonareva, who downed Italy's Roberta Vinci 6-3, 6-3.
When asked what specifically had gone wrong with her serve, Safina had a long list.
"Ball toss disaster. I don't move my legs, I'm jumping backwards instead of jumping forwards, I'm kicking it too much instead of hitting it more, I drop my head, I don't hold the left arm.
"It's so much. I know this all, and I'm still so stupid that I'm continuing to do it."
Safina enlisted help from her coach during the match - but he couldn't help her shake her struggles.
"How can he help me if I'm not doing anything?" Safina said. "I have a game plan and I step on the court, and I do completely the opposite thing.
"He was just frustrated ... he left the court. He said, 'When I'm telling you one thing, and you do completely the opposite thing and you're losing, you're just moving backwards."'
Rezai, who will face either Russia's Alisa Kleybanova or Slovakia's Dominika Cibulkova in round three, felt for Safina after the match.
"I'm very sorry for her because I don't like a player who's not confident," said Rezai, ranked 39th in the world. "I prefer to beat a player in good shape. I'm a player that feels when I lose, it's the worst moment in my life."
Despite the loss, Safina is in no danger of losing her No. 1 ranking - even if No. 2 Serena Williams goes on to win the tournament. Williams hit the court later Wednesday against Kazakhstan's Yaroslava Shvedova.
With less than two weeks until the U.S. Open, Safina said she would use the time to catch her breath.
"I will take a few days off," Safina said. "I think this is the best ... you know, just to recover, and rest. Not much you can do, you know?"
In other action, No. 14 Agnieszka Radwanska of Poland routed Agnes Szavay of Hungary 6-1, 6-1; Shahar Peer of Israel ousted Francesca Schiavone of Italy 7-6 (2), 6-4; and Ukraine's Alona Bondarenko cruised past Alla Kudryavtseva of Russia 6-3, 6-0.
