Andy Murray is through to the semi-finals at Wimbledon after beating Vasek Pospisil in straight sets.

The British no. 1 sealed a 6-4 7-5 6-4 under the roof on Centre Court to book his sixth semi-final appearance at SW19.

He must find a way past the formidable presence of Roger Federer on Friday if he is to repeat his 2013 success, though.

Murray broke his Canadian opponent in the third game of the opening set before rain interrupted play. The Brit simply picked up from where he left off following the resumption of the contest, however, powering his way to a 6-4 win.

The hard-hitting Pospisil threatened to come roaring back in the second and it took Murray until the penultimate game of the second set to break his opponent, before serving out for the win.

In a tense final set where Pospisil avoided four break points, Murray seized the initiative with the scored tied at 4-4, catching his opponent out of position with a powerful backhand. With victory in his sights, he saved break point before sealing his second match point of the game to take a clean straight sets win.

"I felt I played some good stuff," Murray told BBC One after his win. "He served extremely well for periods, I tried to change my return position at the end of the second for myself to see the returns better. It was difficult stopping a couple of times and coming out under the roof."

Federer, meanwhile, powered his way in the final four with a dominant victory over Gilles Simon of France, 6-3 7-5 6-2.

The only surprise in his latest triumph came as the Swiss was broken for the first time in his 68 service games at Wimbledon this year, and while the Frenchman tested him with some enduring rallies, the 17-time major winner prevailed to secure victory on Court One.

"The stop-and-goes with the weather are tough but I think I used them to my advantage," Federer told the BBC after his win. "The breaks helped rather than hindered me.

"Simon was a quality return player and the game I got broken he was too good."
