Jon Rahm will take a one-shot lead into the final round of the European Tour Championship after shooting a third round 65.
But the real scrap is behind him with second-placed Matt Fitzpatrick battling it out with current leader Rory McIlroy to determine who ends the 2022 as the tour's No.1.
The fight for the Harry Vardon Trophy comes down to the last day of the season with McIlroy narrowly leading US Open champion Fitzpatrick in the projected standings following a fine third-round 65 in Dubai on Saturday.
But with Fitzpatrick just one shot behind 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 shot 70.
Swede Alex Noren sat third on 13 under, with McIlroy and halfway co-leader Tyrrell Hatton tied for fourth on 12 under.
Australia's Min-Woo Lee dropped out of contention after carding 74 to be joint 16th on four 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.
The world No.1 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.
"It's been a wonderful year. I've played some really, really great golf and really consistent golf," he said.
"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."
Fitzpatrick, aiming to be crowned European No.1 for the first time in his career, said: "It would mean the world.
"I'm going to need a lot of things go my way [but] I've given myself a chance. I'll do the best I can and fingers crossed."
