DOHA: Andy Murray, widely-tipped to end Britain's 73-year Grand Slam drought this year, beat Roger Federer in the Qatar Open semi-finals on Friday for his fourth win in five matches against the Swiss superstar.
The 21-year-old's stunning 6-7 (6/8), 6-2, 6-2 victory carried him into the final of the Doha event where he is the defending champion and where he will face Andy Roddick on Saturday.
Only a week ago, he had also defeated 13-time Grand Slam title winner Federer in an exhibition event in Abu Dhabi.
Murray was unlucky with a line call at 6-6 in the first set tie-break, which was shown by Hawkeye to be incorrect and happened at a moment when he appeared about to reach set point.
He appeared still to be annoyed when he started the second set, and had to come from love-40 in the third game to save his service.
After that he quickly broke for 4-2 and never looked like dropping his own delivery. When he broke for 3-1 in the final set, it already looked all over for Federer, who appeared to lose heart near the end.
There was also some suspicion that he had been annoyed by some of the spectators though when asked he said: "It's nothing I want to talk about now."
Murray later complained of a back problem which needed treatment in the final set.
Murray has a 5-2 career record over Roddick, who earlier reached his first final since September when he carved a fine win in a high quality match against Gael Monfils.
The former world number one from the United States also showed signs of evolving into a more measured and varied player during his 7-6 (7/1), 3-6, 6-3 win over the brilliant Frenchman.
