Cormac Sharvin claimed his best result since August with a tied-21st finish at the Saudi International as World No.1 Dustin Johnson won the tournament for a second time.
Ardglass man Sharvin fired a two-under 68 in his final round at Royal Greens Golf & Country Club to finish seven-under for the week to record his best finish since the English Championship six months ago.
That was still eight shots adrift of Johnson, who held off the spirited challenge of European Ryder Cup hopeful Victor Perez, America's Tony Finau and former Major champion Justin Rose to claim his fourth win since June.
Johnson was only two-under for the day, however at 15-under overall that was enough to keep his pursuers at bay, with Rose and Finau tied-second at 13-under, while Perez eventually fell away to finish tied-fourth with Callum Hill at 12-under.
The key moment came down the stretch when, with Johnson holding just a one shot lead over Perez, the Frenchman double-bogeyed the 16th, Finau three-putted the same hole and Rose missed an excellent chance at eagle on the par-five 18th.
Masters champion Johnson - who also won this tournament in 2019 - also bogeyed the 16th, but he crucially still held the lead and recovered by birdieing the driveable par-four 17th, allowing him to close it out comfortably down the last for his 26th professional victory.
It was also an excellent week for Sharvin, the World No.406 performing admirably in his first event of the year and emerging from a very strong field up near the top of the leaderboard.
In on a sponsor's invite, the 28-year-old certainly made it the most of it, and he had three birdies to go with just one bogey in his final round in another solid day in King Abdullah Economic City and will now look to use that momentum to kick on.
Graeme McDowell ended his title defence with a two-under 68 of his own to finish tied for 66th - alongside Patrick Reed - at one-over for the week, which will likely not help him move up the world rankings.
Offaly's Shane Lowry had a very disappointing final round, only able to card a two-over 72 to drop back to five-under-par and into a tie for 29th.
