How does the ATP Doubles Team Rankings work?
A. Each team is ranked according to its total points from its best 18 results from all eligible tournaments (Grand Slam, ATP World Tour, including the Barclays ATP World Tour Finals) played in the calendar year. Loser points for the rounds achieved are awarded to players in any tournament not completed. The ATP Doubles Team Rankings are used to determine the year-end World No. 1 team and which eight teams qualify for the Barclays ATP World Tour Finals.
