The 2012 ATP World Tour Finals (also known as the 2012 Barclays ATP World Tour Finals for sponsorship reasons) was a tennis tournament that was played at the O2 Arena in London, United Kingdom between 5 and 12 November 2012.
The 2012 ATP World Tour Finals took place from 5 to 12 November at the O2 Arena in London, United Kingdom. It was the 43rd edition of the tournament (36th in doubles). The tournament was run by the Association of Tennis Professionals (ATP) and was part of the 2012 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 qualify for the event are split into two groups of four. During this stage, players compete 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 progress to the semifinals, where the winners of a group faces the runners-up of the other group. This stage, however, is a knock-out stage. The doubles competition uses the same format.
The Barclays ATP World Tour Finals has a round-robin format, with eight players/teams divided into two groups of four. The eight seeds are determined by the Emirates ATP Rankings and Emirates ATP Doubles Team Rankings on the Monday after the last ATP World Tour tournament of the calendar year. All singles matches are the best of three tie-break sets, including the final. All doubles matches are two sets (no ad) and a Match Tie-break.
The top seeded players/teams are placed in Group A and the second seeded player/team are placed in Group B. Players/teams seeded 3 and 4, 5 and 6, 7 and 8, are then drawn in pairs with the first drawn placed in Group A. Each player/team plays the three other players/teams in his group. The winner of each group (best overall record) is placed in separate semi-final brackets, with the top player/team in Group A playing the runner-up in Group B, and vice versa. If two or more players/teams are tied after the round robin matches, the ties are broken by the Tie-Break Procedure.
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 qualify for the 2012 Barclays ATP World Tour Finals. Countable points include points earned in 2012, plus points earned at the 2011 Davis Cup final and the late-season 2011 Challengers played after the 2011 Barclays ATP World Tour Finals. To qualify, a player who finished in the 2011 year-end top 30 must compete in four Grand Slam tournaments and eight ATP World Tour Masters 1000 tournaments during 2012. They can count their best six (6) results from ATP World Tour 500, ATP World Tour 250 and other events (Challengers, Futures, Davis Cup, Olympics) toward their ranking. To count their best six (6), players must have fulfilled their commitment to 500 events – 4 total per year (at least 1 after the US Open). Additionally, commitment players will no longer need to enter the 500 events 12 weeks in advance but instead go back the normal 6-week entry deadline. If eligible to play in one of the Grand Slam or ATP World Tour Masters 1000 tournaments, a player must count the points from these tournaments, even if it is 'a zero pointer' because he missed the event. Just as in Formula One and numerous other sports, if a competitor misses a race or an event, he loses his chance to earn points. Players with direct acceptance who do not play an ATP World Tour Masters 1000 tournament will be suspended from a subsequent ATP World Tour Masters 1000 event, which will be the next highest points earned ATP World Tour Masters 1000 event within the next 12 months. If an injured player is on site within the first three days of a tournament to conduct promotional activities over a two-day period, a suspension will not be enforced but a 0-pointer will be counted on a player's ranking. If a player does not play enough ATP 500 events and does not have an ATP 250 or Challenger appearance with a better result, the Davis Cup is counted in the 500s table (if the player entered or achieved better results). If a player does not play enough ATP 250 or Challenger events, the World Team Championship is 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 are eligible to be included in his 18 valid tournaments. In teams rankings, Challenger points are excluded.
