KING ABDULLAH ECONOMIC CITY, Saudi Arabia -- Top-ranked Dustin Johnson won the Saudi International for the second time in three years on Sunday after shooting a 2-under 68 in the final round to finish 2 strokes clear of Justin Rose and Tony Finau.
Johnson, who was also runner-up in 2020, recorded his highest scoring round of the tournament at Royal Greens Golf Club but still finished top of the leaderboard at 15-under overall.
Scotland's Calum Hill eagled the par-five 18th to finish in a tie for fourth with France's Victor Perez.
Johnson took a 2-shot lead into the final round, but the 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 1, but he responded in style with a massive tee shot on the next and a pitch to 2 feet to set up a decisive birdie.
"I saw the leaderboard a little bit; the guys were playing well, but I kept giving myself a lot of chances," Johnson told Sky Sports. "I didn't hole many of them but finally holed a really nice putt on 13.
"Seventeen was a really nice birdie, hit a great drive there and a nice little chip, but it was tough all day today.
"I don't get to play around the world as much as I'd like to, but it's definitely nice to get a win not on my tour and after Augusta, to get my first win again, obviously the game is still in really good form and I'm really excited about the rest of the year."
Rasmus Hojgaard, Ryan Fox, Viktor Hovland and Tyrrell Hatton finished in a four-way tie for sixth at 11 under.
The Saudi International is the last of three events in the "Gulf Swing" that launches 2021 on the European Tour.
