Tournament
 
The 2011 ATP World Tour Finals took place from 20 to 27 November at the O2 Arena in London, United Kingdom. It was the 42nd edition of the tournament (37th for doubles). The tournament was run by the Association of Tennis Professionals (ATP) and was part of the 2011 ATP World Tour. The event took place on indoor hard courts. It served as the season-ending championships for players on the ATP Tour. The eight players who qualified for the event were split into two groups of four. During this stage, players competed in a round-robin format (meaning players play against all the other players in their group). The two players with the best results in each group progressed to the semifinals, where the winners of a group faced the runners-up of the other group. This stage, however, was a knock-out stage. The doubles competition used the same format. Points and prize money

1 Prize money for doubles was per team. 2 Pro-rated on a per-match basis: $70,000 = 1 match, $95,000 = 2 matches, $120,000 = 3 matches
3 Pro-rated on a per-match basis: $30,000 = 1 match, $50,000 = 2 matches, $65,000 = 3 matches

Qualification
The top eight players (or teams) with the most countable points accumulated in Grand Slam, ATP World Tour, and Davis Cup tournaments during the year qualified for the 2011 Barclays ATP World Tour Finals. Countable points included points earned in 2011, plus points earned at the 2010 Davis Cup final and the late-season 2010 Challengers played after the 2010 Barclays ATP World Tour Finals. To qualify, a player who finished in the 2010 year-end top 30 must have competed in four Grand Slam tournaments and eight ATP World Tour Masters 1000 tournaments during 2011. The best four ATP World Tour 500 events in 2011 and best two ATP World Tour 250 events in 2011 counted towards the ranking. All direct acceptance players at the time of the entry deadline who did not play an event receive a 0-pointer for that event. The Monte Carlo Rolex Masters 1000 became optional in 2009, but if a player chose to participate in it, its result was counted in and the fourth-best result in an ATP 500 event was ignored (the three best ATP 500 results remained). If a player did not play enough ATP 500 events and did not have an ATP 250 or Challenger appearances with a better result, the Davis Cup was counted in the 500s table (if the player entered or achieved better results). If a player did not play enough ATP 250 or Challenger events, the World Team Championship was counted in the 250s table (if the player entered or achieved better results). If a player could not be present in all required tournament classes (i.e. because of an injury), all uncounted ATP 250 or Challenger results were eligible to be included in the 18 valid tournaments. In teams rankings, Challenger points were excluded. A player who was out of competition for 30 or more days, due to a verified injury, was not penalized. The 2011 Barclays ATP World Tour Finals counted as an additional 19th tournament in the ranking of its eight qualifiers at season's end, while the Davis Cup Final points counted towards the next year's race.

He defeated Rafael Nadal in both those finals in three sets, 4–6, 6–3, 6–2, and 4–6, 6–3, 7–6, respectively. It was the first time since 1995 that Indian Wells and Miami featured the same two finalists and the top 2 ranked players.
