Murray stays flawless in London

New World No 1 Andy Murray's stellar form continued at the ATP World Tour Finals on Friday, as he dispatched Stan Wawrinka 6-4, 6-2 in his final game of the group stages.

The Scot thrilled his home fans in London with the straight sets victory, his third successive win of the tournament, to top the John McEnroe group and set up a semi-final meeting with Canadian Milos Raonic.

It did not take long for Wawrinka to find himself on the defensive. He came through a lengthy third game unscathed but was put under more pressure on serve at 3-3, giving up a break point which Murray snaffled immediately.

Murray earned three more break and set points at 5-3, and even though Wawrinka was able to save them all, he was powerless to prevent his opponent from serving out the set in the next game.

The Scot powered on at the start of the second set, breaking in the first and third games to race into a 4-0 lead.

There was never going to be any way back for Wawrinka there against a player in such a rich vein of form.

Murray would cruise to victory inside 90 minutes to remain on a collision course with Novak Djokovic, the man who he recently supplanted at the top of the world rankings.

"The first set was tight. There weren't many chances," said Murray, 29.

"I managed to get the break late in the set. In the second set I'd already qualified for the semis, so maybe it was easier for me to play more free than him."

Looking ahead to his semi-final opponent Raonic, a player he has beaten eight times in a row, Murray added: "He's played very well in this event. These are quick conditions here and it'll be tough.

"He's got a huge serve. It's an amazing stadium and atmosphere."
