The Barclays ATP World Tour Finals are played at the end of each tennis year, and features the top eight players in the men's world rankings. No women take part.
The format for the competition is a mix of group stages followed by knockout rounds. The first six days are split between two groups of four, with the top two players from each group contesting the semi-finals. The ultimate winner is awarded 1,500 rankings points.
Note: Each session begins with one doubles match, followed approximately two hours later by one singles match. The specific players for each session are only known 24-48 hours before the session begins.
