## Tournament

The 2013 ATP World Tour Finals took place from 4 to 11 November at the O$_2$ Arena in London, United Kingdom.
It was the 44th edition of the tournament (39th in doubles). The tournament was run by the Association of Tennis Professionals (ATP) and was part of the 2013 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. Ties were broken by the Tie-Break Procedure.

## 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 qualify for the 2013 ATP World Tour Finals. Countable points include points earned in 2013, plus points earned at the 2012 Davis Cup final and the late-season 2012 Challengers played after the 2012 ATP World Tour Finals. To qualify, a player who finished in the 2012 year-end top 30 must compete in four Grand Slam tournaments and eight ATP World Tour Masters 1000 tournaments during 2013. They can count their best six 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, 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.
A player who is out of competition for 30 or more days, due to a verified injury, is not penalized. The 2013 ATP World Tour Finals counts as an additional 19th tournament in the ranking of its eight qualifiers at season's end, while the Davis Cup Final points count towards the next year's race.

## Contenders points breakdown

Following his return from injury, Murray came back strong, and had his best ever grass court season, winning the Aegon Championships defeating defending champion Marin Čilić, and then going on to end a 77-year wait for a British male singles champion at Wimbledon, defeating Djokovic in straight sets to clinch his second major trophy, and maintain his 18-match winning streak on grass.
