Davydenko claims ATP Tour Finals title

Nikolay Davydenko won the biggest title of his career with a 6-3 6-4 victory over US Open champion Juan Martin del Potro in the final of the Barclays ATP World Tour Finals at London's O2 Arena this afternoon.

The Russian, who beat Roger Federer in the semi-finals yesterday, went one better than last year having lost to Novak Djokovic in the showpiece 12 months ago.

Del Potro knew victory would take him above Andy Murray - whom he had pipped for a place in the last four by one game - to number four in the rankings but he was thoroughly outplayed.

Davydenko picked up where he had left off against the world number one while Del Potro, who had played quite brilliantly to beat Robin Soderling last night, looked nervous and tentative.

The Russian has been talking all week about his new-found love of volleying and he took every opportunity to put pressure on his opponent.

And it paid dividends in the fourth game, Davydenko taking his second break point after the Argentinian - not for the first time in the tournament - had been pulled up for a foot fault.

This was the Del Potro who had started so hesitantly against Murray in his first match. He was given a chance in game seven when Davydenko double-faulted to go break point down but the 28-year-old is not easily rattled and he recovered to hold and move 5-2 ahead.

The Russian really was playing with supreme confidence and he easily served out a set in which he had barely put a foot wrong.

Del Potro needed something special in the second set and two huge forehand winners in Davydenko's first service game hinted at better to come.

But it was the sixth seed who again had the first break points, in game five, although this time Del Potro proved equal to the challenge, firing down two big serves.

The next game brought the same scenario, with the Russian getting himself out of trouble after for once failing to find the lines.

Davydenko had won two of their three previous meetings, most recently in the group stages of the same tournament last year, and he moved to within sight of victory as some superbly constructed points left his opponent facing three break points at 4-4.

The Russian needed only one, and serving for the match he never looked like faltering, clinching victory when Del Potro netted a forehand.
