Tournament
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 (38th 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 qualified for the event were split into two groups of four. During this stage, players competed in a round-robin format (meaning players played 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.
Format
The Barclays ATP World Tour Finals had a round-robin format, with eight players/teams divided into two groups of four. The eight seeds were determined by the ATP rankings and ATP Doubles Team Rankings on the Monday after the last ATP World Tour tournament of the calendar year. All singles matches were the best of three tie-break sets, including the final. All doubles matches were two sets (no ad) and a Match Tie-break.
Draw
The top seeded players/teams were placed in Group A and the second seeded player/team were placed in Group B. Players/teams seeded 3 and 4, 5 and 6, 7 and 8, were then drawn in pairs with the first drawn placed in Group A. Each player/team played the three other players/teams in his group. The winner of each group (best overall record) was 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 were tied after the round robin matches, the ties were broken by the Tie-Break Procedure.
