Harold Varner III drained a huge eagle putt at the 72nd hole to snatch a landmark victory at the Saudi International.
It looked like the title and the $900,000 winner's cheque was destined to be heading towards Bubba Watson.
Watson, 43, carded a 6-under final round to snatch the clubhouse lead at Royal Greens Golf & Country Club to pile the pressure on Varner III.
The left-hander also made an eagle and a birdie in his final two holes after seemingly coming out of nowhere on the final day.
Varner III looked as if he was going to have to lament a frustrating double bogey at the 14th which looked like it put an end to his chances.
But a birdie at 17 meant that he needed a birdie to force a playoff with the two-time Masters champion. Instead, he drained his eagle putt.

Varner III let out a massive roar in celebration and embraced his caddie. He has never won on the PGA Tour.
The 31-year-old has won on the European Tour before. That victory came at the Australian PGA Championship in 2016.
A 1-under par final round of 69 at the par-70 lay out was enough to get the job done. He had also signed for rounds of 64, 66 and 68.
Elsewhere, England's Steve Lewton was a surprise package and finished inside the top five after finishing at 9-under par for the week.
Cameron Smith joined him on the same score. Matthew Wolff, Tommy Fleetwood and Dustin Johnson finished inside the top 10.
