A quintessential journeyman with just two victories to show for almost three decades of regular pro tour golf, Allan held off three major winners on Sunday to win the Boeing Classic, his third title of the year and second in his past three starts.
And the genial 51-year-old Victorian did it in style as he shot a bogey-free seven-under-par 65 to finish 15 under for the three-day tournament at The Club at Snoqualmie Ridge in Washington.
Left in his wake were three-shot overnight leader Stewart Cink (70), who finished a shot behind, with Ernie Els (66) and Darren Clarke (66) tied for third a further stroke back.
Allan admitted he was a little surprised by the win, which followed victories at The Galleri Classics in March and the Dick's Open in July.
"I think I would have probably laughed if you told me I would have won three times," said Allan, who joined the PGA Tour Champions in 2024 and was playing in his 39th event.
"I definitely thought that I had a win in me, but I wouldn't have said three."
The winner of the 1998 German Open and 2002 Australian Open, Allan played 214 US PGA Tour events and 164 more on the US secondary tour without a win, though he was a runner-up twice on the main tour.
Fast-finishing Allan made a five-foot birdie putt on the par-5 18th on Sunday, then waited to see if Cink could catch him. A stroke behind going into the final hole, Cink left a greenside bunker shot on the lip and made a par.
"It's weird, not something I've ever done before," Allan said of watching Cink play the last hole with the title on the line.
"I think it's really odd because you don't want to wish ill on someone, but obviously you want to win the tournament. He's a great player, so I fully expected him to make a birdie.
"But you know what, at the end of the day if he got up here and made eagle and beat me, so be it. I played well and had a great week."
Allan moved up to seventh place in the tour's points standings after joining illustrious Spaniards Miguel Angel Jiminez (four) and Angel Cabrera (three) as three-time winners in 2025.
He is now behind only greats Bruce Crampton (20), Graham Marsh (six) and David Graham (five) for most wins by an Australian on the 50-and-over tour.
