ATP World Tour Finals 2012: Day 8 Scores, Results and Recap

The ATP World Tour Finals came to a triumphant end at the O2 Arena in London, England on Monday as champions were crowned in both the men's singles and doubles competitions, wrapping up what has once again been an exciting event that captured the attention of tennis fans around the globe.

Here's what went down on the final day of the season.

Men's Doubles

No. 6 Marcel Granollers and Marc Lopez defeated No. 5 Mahesh Bhupathi and Rohan Bopanna

The No. 6- seeded Spaniards took down a tough Indian duo by a score of 7-5, 3-6, 10-3 to clinch the men's doubles title on Monday afternoon.

It was the third title for the pair this year, having already won competitions in Rome and Gstaad earlier this season. They became the first Spaniards to win the title since 1975, when Juan Gisbert and Manuel Orantes stood victorious at center court.

It was a competitive match that went back and forth much of the afternoon, but the turning point came in the champion's set, when Granollers and Lopez jumped out to an early double mini-break to lead 4-0, something from which Bhupathi and Bopanna could not recover.

You have to feel for Bhupathi, who has now lost each of the five finals in which he's appeared in at the ATP World Tour Finals.

Men's Singles

Men's Final: No. 1 Novak Djokovic defeated No. 2 Roger Federer 

As USA Today noted, this one got off to a rocky start for the No. 1-ranked player in the world:

Whether it was an honest mistake or an attempt to rattle his nemesis, it seemed to pay dividends for Federer, as he took the first nine points of the afternoon to take a 3-0 lead in the first set. Yet Djokovic would not come unglued, and he rallied for the win, 7-6 (8-6).

The Wimbledon champion would once again take the lead in the second set but, as if on cue, the Australian Open champ battled his way back, taking the final set of the season 7-5 and winning his second ATP World Tour Finals championship, the other coming in 2008.

For Federer, who was going for his seventh career title at the event and third in a row, he finishes the year having lost to Djokovic three times in five attempts, having lost in Rome and at Roland Garros, and now in London.
