Rory McIlroy and Matt Fitzpatrick will battle it out in the final round of the DP World Tour Championship to decide who ends 2022 as European number one.
The fight for the Harry Vardon Trophy comes down to the last day of the season, as world number one McIlroy narrowly leads US Open champion Fitzpatrick in the projected standings following a fine third-round 65 in Dubai.
But, with Fitzpatrick just one shot off the tournament lead held by their Ryder Cup team-mate Jon Rahm with 18 holes remaining, there is everything to play for on Sunday.
Rahm's bogey-free 65 took the two-time former champion to the top of the leaderboard on 15 under par.
Fitzpatrick, also looking for his third win at Jumeirah Golf Estates' Earth Course, was a shot further back in second following his 70.
Swede Alex Noren sat third on 13 under, with McIlroy and halfway co-leader Tyrrell Hatton tied for fourth on 12 under.
McIlroy came into the season finale at the top of the rankings, but opening rounds of 71 and 68 handed the advantage to Fitzpatrick.
The Northern Irishman hit back on Saturday, though, carding an eagle, seven birdies and two bogeys to climb the leaderboard.
He treated the huge crowds to some exhibition golf, coming close to holing his approach shots at the eighth and ninth before tapping in for birdies there.
McIlroy, who also won the FedEx Cup title on the PGA Tour in 2022, feels landing the Harry Vardon Trophy would be an excellent way to end a fantastic year.
"I've never won the FedEx Cup and this tour's rankings in the same year, so it would be really nice.
He said: "It's really cool, I've got to this stage in the game, over 15 years as a pro, and I'm still trying to do things for the first time.
"I've never won the FedEx Cup and this tour's rankings in the same year, so it would be really nice.
"It's been a wonderful year. I've played some really, really great golf and really consistent golf.
"If I'm able to go out there tomorrow and shoot a good score and get the job done, it would be a really nice way to end what's been a great year."
