Novak Djokovic secured a 7-6 (8-6) 7-5 victory over Roger Federer in an incredible end to the ATP Tour Finals.
The world's top two players did the season-ending match justice in a tussle that swung from one way to the other before the Serb carved out a victory in straight sets.
It was Federer who was out of the blocks quickest, with Djokovic having to wait ten points before he was able to get on the board as Federer opened the match with two love games as he stormed to a 3-0 lead.
The demolition act may have brought back memories of the Swiss maestro's hammering of Llyeton Hewitt in the 2004 US Open final in which he took the first set in just 18 minutes, however, with the greatest respect to Hewitt, Djokovic is a beast of quite a different nature.
Djokovic showed just that at 3-1 when he capitalised on the first break point that came his way to get back into the match. He took it one step further in an incredible ninth game, with Federer serving, that lasted nine minutes and 20 seconds as both players slugged it out in rallys of the highest quality. It was Djokovic who triumphed though, setting up an opportunity to serve for the set at 5-4.
One would be a fool to write Federer off at any stage and he lived up to his reputation as he bounced back with ease to level matters at 5-5.
A tie-break was required to separate the players in the first set and once again it was Djokovic who just had that little bit extra when it mattered as he took the breaker 8-6 and with it the set.
Again Federer would not go quietly, breaking the world number one first up in the second set in another marathon game that lasted in excess of ten minutes.
With the break in his pocket the level of tennis dropped off a tad in the games that followed. For a moment it seemed that Djokovic seemed almost resigned to losing the set. Such presumptions would prove wholly wrong.
Serving for the set at 5-4 and 40-15 up, the unforced errors that had crept into Federer's game came back to haunt him as he allowed Djokovic a glimmer of hope that was duly seized upon.
A hold from the challenger followed and suddenly Federer was serving to stay in the match. A few sloppy groundstrokes later and Djokovic had match point.
He didn't need a second invitation either, producing a scintillating forehand up the line to claim the victory 7-6 7-5 in what was a titanic battle.
Both men have enjoyed very successful years, but perhaps correctly it is Djokovic who end the year with a win and the number one ranking.
