NASSAU, Bahamas — The 24-year-old rising star put a nice ribbon on a three-win year in golf by posing with Tiger Woods at the trophy presentation Sunday in the Hero World Challenge.

It just wasn’t the winner anyone imagined.

Not even Viktor Hovland thought it was realistic he could rally from 6 shots behind Collin Morikawa, the steady hand who was poised to reach No. 1 in the world with a victory.

Instead, the Norwegian did the unthinkable in a final round at Albany that was pure chaos.

He looked up from a greenside bunker on the ninth hole and saw Morikawa sliding fast with a pair of double bogeys. Hovland seized on the opportunity with back-to-back eagles and closed with a pair of bogeys he could afford for a 6-under 66 and a 1-shot victory.

“I didn’t think a win was going to be very possible,” Hovland said. “But I know this course is tricky. You can make birdies, but it’s easy to make bogeys and doubles. If I put a good score up there, you never know what’s going to happen.”

Just about everything did.

On the same hole Hovland holed a bunker shot for eagle, Sam Burns went from a tie for the lead to a triple bogey when it took 5 shots to get up a slope from 15 yards away. Jordan Spieth and Henrik Stenson were penalized 2 shots for hitting shots off the 17th tee while playing the ninth hole. Scottie Scheffler was 7 shots behind, made a triple bogey on his fourth hole and still nearly won.

The biggest surprise was Morikawa — Hovland’s roommate for the week at Albany — who took a 5-shot lead into the final round and wasn’t even a serious factor over the final hour. Two double bogeys and a 41 on the front nine sent him to a 76.

“A little sad to see him not play his best today,” Hovland said. “He’s a great player and I expected him to just kind of roll away with the victory. But sometimes this sport is not that easy and I’m sure he’ll come back even stronger.”

Ultimately, this was about the other 24-year-old adding to his big year after wins in Germany on the European Tour and Mexico on the PGA Tour. His third win of the year against a 20-man elite field moved him to No. 7 in the world.

Morikawa, the Open champion and first American to be No. 1 on the European Tour and newly engaged as of Tuesday, looked like he would breeze to a fourth win of the year in the Bahamas.

But he missed three birdie chances from 10 feet or closer at the start of the round and then went sideways when his approach on No. 4 sailed into a big bush and led to double bogey, and the same thing happened — presumably with mud on the ball — at the par-5 sixth for another double bogey. A chunked wedge on the par-5 ninth led to bogey.

A victory would have made him the 25th player to reach No. 1 in the world since the ranking began in 1986. That position still belongs to U.S. Open champion Jon Rahm, who didn’t play this week.

Hovland was among five players who had at least a share of the lead at some point. That changed on the reachable par-4 14th.

In the group behind Burns, who made his triple bogey, Hovland had a lie so challenging in the bunker he thought about aiming away from the flag to make sure it stayed on the green.

“But I decided to just give it some extra speed, which has kind of been one of the things I’ve been struggling with around the greens,” he said. “If it’s a high-pressure situation, I tend to hit it soft instead of going for the open face and hit it hard. And I decided to do that there and it worked out.”

He followed with a 7-iron to 20 feet on the par-5 15th for eagle to stretch his lead, and he wasn’t done. Hovland’s next shot dropped next to the cup for a 3-foot birdie.

He finished at 18-under 270.

Scheffler narrowly missed a fifth straight birdie on the 18th hole. He shot 66 and finished 1 shot behind, ending a year in which he made a sterling Ryder Cup debut but still has yet to win on the PGA Tour.

Bryson DeChambeau finished his day with a triple bogey from the water. He was leading after 36 holes and finished in a tie for 14th in the 20-man field.

Spieth and Stenson were at the bottom of the pack all day, and they were assured of staying there when they walked back to where the ninth tee had been all week, not realizing that it was used as the tee for the par-3 17th hole and they should have been playing about 25 yards farther ahead. They had to replay the hole and add 2 shots to their score.

It was that kind of day, and the action never stopped until Woods — in a red shirt, of course — handed the trophy to the Norwegian. Hovland is the third straight international winner, following Henrik Stenson and Rahm.
