ATP World Tour Finals 2013: Novak Djokovic Thumps Stanislas Wawrinka to Book Final Against Rafael Nadal

Defending champion Novak Djokovic stormed into the final of the ATP World Tour Finals against Rafael Nadal after a dominant display dismissed Stanislas Wawrinka in two sets at London's O2 Arena.

Djokovic's 6-3 6-3 victory ended Wawrinka's debut run in the season ending finals and booked a final on Monday against Nadal, the year ending world No.1, and extend his unbeaten run to 21 matches since the US Open.

Wawrinka forced an early break in the first set but once Djokovic had regained parity the six-time grand slam champion powered through in 84 minutes amid his most convincing display of the tournament.

Defeat ends Wawrinka's stunning 2013 season in anything but anticlimactic fashion while the year now closes with a final fittingly contested between the world's top two players.

Having won their last 12 meetings and prevailed three times in 2013, Djokovic was the overwhelming favourite to join Nadal, who had earlier defeated Roger Federer, in the final but after the most successful year of his career Wawrinka was in no mood to go down quietly.

And the Swiss provided an early blow to display his indications, breaking the world No.2 as early as the third game, producing a beautifully whipped forehand cross-court before a volleyed winner saw him hit the front.

Djokovic's reaction was immediate, levelling the first set as Wawrinka miss-hit a forehand to hand back the initiative.

The momentum firmly swung the way of the Serbian in game eight as a pair of Wawrinka errors on the forehand side gave Djokovic two break chances and while the Australia Open champion netted the first, an outstanding rally then ended with the world No.8 netting.

The fierce exchange worked to enhance Djokovic's status as the best defender on tour and seemed to deflate the Wawrinka charge and as the defending champion converted the second of three sets points he had the set lead to add to his psychological stronghold.

A break early in the second set for Djokovic following another lengthy rally threatened to turn the contest into a humiliating episode for Wawrinka, but he did save break points when seemingly on the brink at 2-0 to give himself a lifeline.

More break chances came and went for Djokovic as his defensive powers continued to hold no bounds but Wawrinka was unable to convert such resilience into pressure on his opponents' serve and when handed the first of two match points the Paris Masters champion made no mistake to confirm his place in Monday's showpiece final.
