LONDON (Reuters) - Home favorite Andy Murray stayed afloat at the ATP World Tour Finals with a 6-3 7-5 defeat of big-serving Canadian Milos Raonic on Tuesday.
After losing to Japan's Kei Nishikori in his opening Group B match at the season's finale on Sunday, Murray knew only a win against Raonic would keep his hopes alive and he duly delivered with a solid display at a jam-packed 02 Arena.
Murray needed one break of serve to clinch the opening set and struck again at 5-5 in the second as Raonic faltered.
He clinched victory in one hour 31 minutes and on his second match point and will now go into his final Group B match against six-times champion Roger Federer on Thursday with a place in the semi-finals at stake.
Federer is top of the group with a 100 percent record after beating Nishikori earlier.
