Qualification scenarios for the Nitto ATP World Tour Finals

Players who are out of contention:

Novak Djokovic:

12 time Grand Slam champion Novak Djokovic has had a year to forget. Apart from the title at Doha right at the beginning of the year, it has gone downhill for Djokovic since then.

He was upset in the Australian Open and was thrashed by Dominic Thiem at Roland Garros. A longstanding elbow injury forced him to retire in his quarter-final match at Wimbledon which led to him withdrawing from the rest of the season.

He will be back in action at the Australian Open next year and will be ranked outside the top 10.

Andy Murray:

Just like Djokovic, Britain’s Andy Murray, too, has had a year to forget. Apart from a semi-final at Roland Garros, Murray has had nothing to show for.

He has suffered from constant hip injuries throughout the year which led to his withdrawal from the US Open and the tournaments prior to that.

He has not confirmed his absence for the rest of the year, but will most likely do so. If not, he has lost too many points and thus won't be able to qualify for the tour finals.

Stan Wawrinka:

It was a year marred with injuries and Stan Wawrinka was another addition to the unfortunate list. However, the three-time Grand Slam Champion had a few noteworthy performances which included the French Open final and Australian Open semifinals.

He also reached the final of the Indian Wells Masters where he lost to Federer. He announced his absence from the rest of the season after Wimbledon and has undergone surgery since then.
