Stanislas Wawrinka qualified for the semi-finals of the ATP World Tour finals with a 6-3 4-6 6-3 victory over Marin Cilic.
The Swiss third seed needed just three games to set up a last four clash against compatriot and close friend, Roger Federer, in Saturday's semi-finals at the O2 Arena.
He quickly broke the Croatian's serve to move into a 3-1 lead after just 13 minutes in the opening set of their final round-robin match and from then on the contest took on the nature of an exhibition match.
Wawrinka surrendered the second set to the US Open champion, seeded eight here, but broke twice in the decider and wrapped up victory when Cilic served a double fault on the second match point.
Earlier, champion Novak Djokovic had defeated Tomas Berdych 6-2 6-2 to ensure he would meet Japan's Kei Nishikori in Saturday's first semi-final.
"It was a tough match, it's never easy to play against Marin, he's been having an amazing year," said Wawrinka. "To win is important for me."
Wawrinka has played countryman and good friend Federer 16 times and won only twice, but one of those came this year in the final of the Monte Carlo Masters.
He said: "I hope I can get a little bit of support because I know people love him here. It's going to be tough for me, but I need to trust myself and go for it."
