The Race to Dubai reaches its conclusion this week at the season-ending DP World Tour Championship. We look at the seven players still in with a shout of ending the year as the European Tour's No 1.
Rory McIlroy - 3,393,923 points
The world No 3 heads in to this week's final with a slender lead, little over 1,600 points clear of the rest of the pack after those around him closed the gap at the BMW Masters.
Despite missing a large chunk of the summer with an ankle injury, early season victories at the Omega Dubai Desert Classic and the WGC-Cadillac Match Play as well as top-10 finishes in the opening two majors keeps him just about ahead.
For him to go on and secure Race to Dubai victory for the third time in four seasons, McIlory needs to finish higher than Danny Willett this week.
Danny Willett - 3,992,310 points
Willett has been a permanent fixture in the Race to Dubai's top-two throughout the year, winning the season-opening Nedbank Golf Challenge in the first of two victories during 2015.
Having failed to capitalise on McIlroy's absence from Shanghai, a tied-28th finish last week means he has to beat the Northern Irishman's score this time around.
Should he finish above the world No 3 and inside the top nine, then would need a victory from one of the chasing pack to deny him from winning the Order of Merit.
Justin Rose - 2,742,924 points
Up to third in the standings with a top-10 showing in Shanghai, Rose is now on course to finish in the top three in the Race to Dubai for the fourth season running.
A win for Rose would need McIlroy or Willett to finish third or worse, while a solo second finish for the Englishman would leave the pair having to end inside the top eight.
Shane Lowry - 2,691,444 points
A couple of disappointing weeks has left the Irishman with a lot do in the season finale. Failing to finish inside the top 50 in either of his past two starts means a win or solo second is the minimum he now needs to have a chance.
Solo second would be enough for the WGC-Bridgestone Invitational winner to take the crown should McIlroy and Willett not end up in the top 10, providing Rose, Louis Oosthuizen or Branden Grace do not top the leaderboard.
Although Lowry is nearly 700,000 behind the top of the standings, a win would be enough if the leading pair don't finish inside the top three.
Louis Oosthuizen - 2,655,907 points
As long as McIlroy and Willett end the week 12th or worse, then the US Open runner-up could end the year as European No 1 with solo second, while victory would need the duo to end inside the top three.
Although he has finished inside the top 30 in all four Majors this season, Oostuhuizen heads to Dubai fifth in the standings and somewhat out of touch and without a top-10 in his past seven starts worldwide.
Branden Grace - 2,556,148 points
Grace looks like a man in form having finished in the top five in each of his past four starts, following on from two victories earlier in the season.
The Qatar Masters champion also needs a win or to finish solo second to have a chance of overtaking the top two in the standings.
A win would be enough should McIlory and Willett come in third or worse, but a solo second would need the pair to finish lower than 43rd in the 60-man field.
Byeong Hun An - 2,139,356 points
The South Korean would become the first rookie in history to top the order of merit standings, but the BMW PGA Champion would need an unlikely set of circumstances for him to take the title.
With An more than a million points off the lead, only a win will keep his slim hopes alive. If he could pull off a victory, then he'd need McIlroy and Willett to both finishing 29th or worse, as well as the chasing pack to have a quiet week away from the top of the leaderboard.
