Padraig Harrington fired a superb 67 to finish fourth at the Abu Dhabi HSBC Championship, though it was France's Victor Perez who took home his third DP World Tour victory at Yas Island.
Meanwhile, it was a miserable Sunday for Shane Lowry, whose round tailed off badly after he briefly led on the front nine.
Perez survived a nervous finale to win by one shot after a shooting a six-under-par 66 in his final round.
The Dundee-based Frenchman began his final round one shot adrift of Lowry, Francesco Molinari and Australia's Min-Woo Lee.
Having established a two-stroke lead with four successive birdies between the 8th and 11th, Perez appeared to be wobbling slightly with a dropped stroke at 14 before finding the bunker at the tricky short 17th hole.
With Min-Woo Lee, Harrington and Sweden's Sebastian Soderbergh nipping at his heels, the Frenchman proceeded to hole out from the bunker, celebrating wildly with his caddie.
It looked unassailable before he found another bunker and then the penalty area on the 18th but he took his medicine with a bogey to finish on a victorious 18-under-par total.
Lee and Swede Sebastian Soderberg finished tied for second after shooting 68 and 67 respectively.
It was a third DP World Tour win for Perez, after previous victories at the 2019 Alfred Dunhill Championship and the 2022 Dutch Open.
"It's a great year ahead, there's a lot of big things coming up, I've had a good off-season, I've worked really hard. It's just great," the tearful Frenchman told Sky Sports after winning.
After a stunning 64 catapulted him up the leaderboard on Saturday, Harrington was rocked early with bogey on the first, undoing some of the damage with a birdie at the par-five second.
A birdie at the fifth was cancelled out by a ugly three-putt bogey from a short distance at the par-five seventh. By now, the prospect of victory appeared especially remote, however, the three-time major winner caught another hot streak.
In his third round, Harrington had rattled six birdies on a row between 11 and 16, at one stage tying the lead with his compatriot Lowry.
On Sunday, the numbers weren't too dissimilar, with five birdies arriving in seven holes between the eighth and 14th, with Harrington's wedge play setting up numerous opportunities.
When Perez bogeyed 14, Harrington was only one stroke off the lead. But the Dubliner was unable to find any more birdies, the Frenchman making the decisive move when holing out from the bunker on the 71st hole.
Harrington eventually for a fourth place finish, tapping in for par on 18 to complete a final round of 67.
It was a different story for Lowry, who endured a horror show down the closing stretch to tumble out of contention, eventually winding up in a tie for 21st.
Things began smoothly enough. Lowry, who won the event in 2019, birdied the par-five second hole and then took sole possession of the lead following after sinking a 14th birdie on the fifth.
However, a pair of bogeys, the first arriving at the par-five sixth, saw him reach the turn in 36 strokes, while others took the initiative.
Back-to-back birdies on 12 and 13, the second after he drained a 27ft putt enlivened his interest in the competition once more and he only trailed by two.
But his momentum would be halted with a bogey following another poor tee shot at 14 and his round imploded from there.
From the rough at 16, Lowry shanked his recovery into the water and wound up with a triple bogey, ultimately slipping back to nine-under par overall with a closing 76.
Such were Lowry's struggles that Waterford's Seamus Power, never seriously in contention, ultimately placed second best of the Irish contingent.
Power's closing round of 69 included an eagle at the 7th, as well as three birdies on the inward nine as he finished tied-20th.
