Padraig Harrington rolled back the years with a stunning final round at the Portugal Masters to claim his first European Tour sanctioned event since 2008.
The Irishman had not tasted success since winning the dual-sanctioned US PGA Championship eight years ago, but carded a 65 on Sunday to finish 23-under and pip Andy Sullivan by one stroke.
Harrington started the final round one shot off the pace but quickly moved level with overnight leader Anders Hansen with a birdie at the second.
He collected another shot at the seventh but was behind defending champion Sullivan after the Englishman picked up four shots in his first five holes.
It was the back nine that saw Harrington clinch victory, his fifth birdie of the day coming at 14 as he hit the front for the first time thanks to a beautiful approach that spun to within five feet.
Sullivan then missed a chance to level at 15 as the final round reached a nail-biting finale.
A great par save at 16 kept Harrington on track, only for Sullivan to apply pressure with a birdie at 17 to join the Irishman on -22.
However, Harrington was able to replicate that feat and it proved decisive as both men parred the last with nerve-jangling putts.
Hansen and Mikko Korhonen were also in contention throughout the final day but birdies proved tough to come by for the pair and they had to settle for a tie of third on 21-under.
It could have been a fairytale story for Hansen after he retired from golf at the same event 12 months ago, while Korhonen's efforts ensured he retains his European Tour card for 2017.
