TORONTO (AP) Top-seeded Novak Djokovic was upset by 13th-seeded Jo-Wilfried Tsonga in the third round of the Rogers Cup on Thursday.
Djokovic came in with 11 straight wins over Tsonga but was nowhere near adding a 12th.
Tsonga's serve gave Djokovic plenty of trouble. The Frenchman had only eight aces, but Djokovic continually struggled to keep his returns in play.
Serving on match point, Tsonga clinched the win when Djokovic's return went wide.
Djokovic never looked comfortable in Toronto. He was coming off a 6-2, 6-7 (4), 7-6 (2) second-round win over Gael Monfils a day earlier.
Tsonga will play Andy Murray or Richard Gasquet in the quarterfinals.
It was the second big upset of the day. Third-seeded Stan Wawrinka lost 7-6 (8), 7-5 to Kevin Anderson.
