Dustin Johnson has held his nerve to win the Saudi International for the second time in three years and extend his lead at the top of the world golf rankings.
The American, who was also runner-up in 2020, carded his worst round of the tournament on Sunday with a two-under 68 at Royal Greens Golf Club, managing only three birdies.
But it was enough to win as Johnson finished the tournament at 15-under par, two shots ahead of Justin Rose and Tony Finau.
Scotland's Calum Hill eagled the par-5 18th to finish in a tie for fourth with France's Victor Perez in the European Tour tournament.
"Conditions when we started were really tough," Johnson said.

"I knew I was hitting it well, I saw the leaderboard and I knew the guys were playing well.
"I kept giving myself chances, I didn't hole any of them but I hit good shots and I finally holed a really nice putt on 13 and from there on I played solid.

Johnson took a two-shot lead into the final round but the 2020 Masters champion struggled on the greens and was caught by Finau when his fellow American made a hat-trick of birdies from the 11th.
However, Johnson edged back in front with a birdie on the 13th and was given some welcome breathing space when Finau dropped shots on the 16th and 17th and Perez double-bogeyed the 16th.
Johnson also dropped a shot on the 16th to see his lead cut to one, but responded in style with a massive tee shot on the next and a pitch to two feet to set up a decisive birdie.
