The European Tour season reaches its climax this week at the DP World Tour Championship, with six players still in the running to end the season European No 1.
The season finale at Jumeriah Golf Estates marks the end of hectic 40-tournament schedule, played across 20 countries, with the event also the last before the European Tour is rebranded as the DP World Tour from next week.
Only the leading 50 eligible players in the Race to Dubai standings automatically qualify for the Rolex Series event, while Sergio Garcia and Patrick Reed received special exemptions to play and Will Zalatoris is also in the field due to his world ranking.
Collin Morikawa holds a slender 236-point advantage at the top of the standings, but the 2,000 points awarded to this week's winner means that anyone as low as Paul Casey in seventh spot can still claim the Race to Dubai title.
Morikawa is the highest-ranked player in the field, following Jon Rahm's decision not to feature, with the world No 2 holding top spot since following his first WGC-Workday Championship in March by registering a second major title at The Open in July.
The 24-year-old's closest challenge comes from compatriot Billy Horschel, BMW PGA champion in September, with both players bidding to become the first American winner of the Race to Dubai and the only two who can guarantee top spot with a victory.
Morikawa could finish bottom and still win the Race to Dubai, providing Horschel finishes outside the top-nine this week and none of the other four contenders win, while Horschel could finish as low as eight - depending on other results - and still end the season top of the standings.
Tyrrell Hatton, Min Woo Lee, last year's DP World Tour Championship winner Matt Fitzpatrick and compatriot Paul Casey are the other quartet still in the running to win the Race to Dubai, although all four require a win and a several permutations to work in their favour.
Scenarios needed for Race to Dubai victory
Hatton - Victory, Morikawa worse than tied-third, Horschel outside three-way tie for second
Lee - Victory, Morikawa worse than tied-seventh, Horschel outside the top-four
Fitzpatrick - Victory, Morikawa outside the top-nine, Horschel worse than fifth
Casey - Victory, Morikawa outside the top-12, Horschel sixth or worse
