Top-ranked Novak Djokovic was upset by 13th-seeded Jo-Wilfried Tsonga on Thursday in the Rogers Cup, falling 6-2, 6-2 in only 63 minutes in the third round.

Second-seeded Roger Federer narrowly avoided another upset, edging Marin Cilic 7-6 (5), 6-7 (3), 6-4.

Djokovic came in with 11 straight wins over Tsonga but was nowhere near adding a 12th.

“Just nothing was going,” Djokovic said. “No baseline, no serve, no return. So just generally (a) very bad day, very poor performance.

Tsonga’s serve gave Djokovic plenty of trouble. The Frenchman had only eight aces, but Djokovic continually struggled to keep his returns in play and Tsonga pulled off a victory he relished.

“It’s not every day you get the rewards of what you’re doing every day during the year,” he said. “You leave your family, practice every day hard, suffer a lot on the court. And when you win a match like this, you just feel good.”

Djokovic never looked comfortable in Toronto, his first tournament since winning Wimbledon last month. Four days later, he married his longtime girlfriend. On Wednesday, Djokovic needed three tough sets to outlast another French player Gael Monfils.

“I wasn’t hitting the ball clean and a lot of unforced errors,” said Djokovic.

Tsonga will play eighth-seeded Andy Murray in the quarterfinals. Murray advanced when third-round opponent Richard Gasquet withdrew because of an abdominal strain.

FEDERER STRETCHED

Federer faced only two break points throughout his contest against Cilic, saving both, but still had difficulty dispatching the resolute Croat, who saved six match points during the second set and eventually took it in a tiebreak.

Federer’s quarterfinal opponent will be David Ferrer. The Spaniard, also pushed to three sets by Croat Ivan Dodig, won 1-6, 6-3, 6-3.

Third-seeded Stan Wawrinka failed to make it two Swiss in the last eight, as he was beaten 7-6 (8), 7-5 by Kevin Anderson. Anderson will play seventh-seeded Grigor Dimitrov, a 7-5, 5-7, 6-4 winner over Tommy Robredo.

Milos Raonic also advanced in his home tournament, beating Julien Benneteau of France 6-3, 4-6, 6-4. The sixth-seeded Raonic will play Feliciano Lopez in the quarterfinals.

Goodbye kvitova

Serena Williams cruised into the quarter-finals of the Rogers Cup with a 7-5 6-4 win over Lucie Safarova, while sister Venus ousted Angelique Kerber as the Montreal tournament lost more high seeds on Thursday.

Petra Kvitova, ranked No. 2 and playing in her first event since winning her second Wimbledon title, fell 6-4 1-6 6-2 to Russia’s Ekaterina Makarova while fourth seed Maria Sharapova was beaten 6-2 4-6 6-2 by Spain’s Carla Suarez Navarro. German sixth seed Kerber and seventh seed Jelena Jankovic of Serbia were also sent packing, leaving just two of the top eight seeds — Serena Williams and third seed Agnieszka Radwanska of Poland — in the quarter-finals.

While not as ruthless as in her 6-2 6-0 demolition of former-U.S. Open champion Sam Stosur in her opening match, the American still delivered on the big points when it mattered against her 15th-seeded Czech opponent.

“I really needed to serve well today because she was just hitting unreturnable serves for me,” said Williams. “We didn’t really have too many long rallies.

Williams will now face Denmark’s former world number one Caroline Wozniacki, who brought American qualifier Shelby Rogers’ fairytale run to a shuddering 6-1 6-0 end, in the quarter-finals.

“I would need to try and make her move, try and open up the points, serve well myself,” she said.
