ATP Finals 2017
November 12-19, 2017 -- The Barclays ATP World Tour Finals take place in London, featuring the world’s top eight-ranked players over the year. Rafael Nadal, guaranteed to finish the season as World No.1 for the fourth time, will face tough competition to secure his seventh title of 2017 from Australian Open and Wimbledon champion Roger Federer, hoping to claim a first ATP Finals crown since 2011.
The season-ending ATP World Tour Finals in London is played between the top eight players with the most ranking points collected during the calendar year. Points that contribute to the Race to London ranking are accumulated in the Grand Slam, ATP World Tour (ATP World Tour Masters 1000, ATP World Tour 500 series, and ATP World Tour 250 series), and Davis Cup tournaments.
Ranking points are awarded for each event - ranging from 2,000 for the winner of a Grand Slam tournament to 250 for the winner of a 250 series event.
To quote Wikipedia: “Unlike all other singles events on the men's tour, the ATP World Tour Finals is not a straightforward knock-out tournament. Eight players are divided into two groups of four and play three round-robin matches each against the other players in their group. The two players with the best records in each group progress to the semifinals, with the winners meeting in the final to determine the champion.“
