Tsonga knocks out Federer

Jo-Wilfried Tsonga battled back from 5-1 down in the deciding set to beat a stunned Roger Federer in the last eight at the Rogers Cup.

The Frenchman beat the world number one 7-6 (7/5) 1-6 7-6 (7/3) in two hours and 19 minutes in Montreal.

He will play Andy Murray in the last four after the Scot made short work of Nikolay Davydenko, beating the Russian 6-2 6-4 earlier.

Tsonga took the first set on a tie break after saving two break points, but Federer looked on course for victory when he raced through the second for the loss of just one game and moved 5-1 ahead in the third.

The seventh seed dug deep to reel off five straight games though, and had three match points at 6-5 and 40-0 against the Federer serve, only for the Swiss to save them all.

Tsonga was not to be denied in the tie-break, as Federer handed him victory with an uncharacteristic double fault.

Earlier Murray capitalised on the catalogue of errors by Davydenko, who had gone into the game on a 12-match winning streak, to claim victory in one hour and 21 minutes.

Murray converted all four of his break points, the last in the final game of the match when Davydenko went long with yet another unforced error.

The Scot dropped his serve once in the opening set, but that was to prove the only impact his opponent made.

"The start was important," Murray said afterwards on Sky Sports Xtra.

"When he broke me back in the first set it was important for stay strong there because he was actually making quite a lot of mistakes in the first set and I didn't want to let him back in, let him get into a rhythm.

"I felt pretty comfortable after the first set. My serve was helping me out, I didn't give him many chances in the second set.

"It's very difficult playing against him. He stands so close to the baseline, he hits the ball really hard and flat, you need to be on the defensive a lot against him. I managed to defend well and use my slice to change the pace of the ball."

The quarter-final line-up at Montreal featured the top eight players in the world, with Andy Roddick taking on Novak Djokovic and Juan Martin Del Potro playing Rafael Nadal in the other two last-eight matches.
