Hobbled by an ankle injury and on crutches three weeks ago, Roger Federer did something practically unheard of - he lost a match. The top-seeded Swiss came within two points of a third consecutive Tennis Masters Cup triumph before losing in five sets to David Nalbandian on Sunday.

Federer, who hadn't lost in 24 finals, was beaten 6-7 (4), 6-7 (11), 6-2, 6-1, 7-6 (3) for only his fourth defeat this year. Nalbandian ended Federer's 35-match winning streak and his bid to equal John McEnroe's 21-year-old mark of 82-3 for the best winning percentage in a season in the Open era.

"Roger, don't worry, it's not your last final," Nalbandian joked. "You're going to win a lot of tournaments, so let me keep this one."

Nalbandian was ranked 12th before the tournament and was summoned to the eight-man field when Andy Roddick pulled out with an injured back. He had to cancel a fishing trip to travel to Shanghai.

"He caught a big enough fish today - Roger Federer," Nalbandian's translator said at the post-match news conference.

"To win like this, it's really incredible," said Nalbandian, who earned $1.4 million in prize money and improved his year-ending ranking to a career-high No. 6.

Federer said he'd never expected to make it so far at the season-ending tournament when he limped into Shanghai last week.

"I feel like I've had a great year and a great tournament," he said. "Disappointment is always there, because I don't lose very often. ... I still get that feeling. It's good like this."

Besides, he said, "I came much closer than I ever thought I would come to this tournament victory. It was unfortunate in the end. I cannot believe myself I came back in the fifth, but somehow I did. There's also pride in there because three weeks ago I was still on crutches."

Federer injured his right ankle the week after ensuring the year-end No. 1 ranking with his 11th title of the year on Oct. 2 in Thailand.

He couldn't practice or run until the week before the tournament. And with No. 2-ranked Rafael Nadal, No. 3 Roddick, No. 4 Lleyton Hewitt, No. 5 Andre Agassi and Australian Open champion Marat Safin withdrawing either before or right at the start of the tournament, there was extra pressure on Federer to win.

He rallied from 0-4 in the deciding set and was serving for the match at 6-5 and 30-0 before Nalbandian broke back to force a tiebreaker. Nalbandian earned three championship points when Federer sent a backhand into the net. The eighth-seeded Argentine clinched the 4 1/2-hour match when Federer netted a forehand.
