Viktor Hovland pounces to claim the Hero World Challenge

The American, who has won two Majors Championships and the DP World Tour's Race to Dubai in the last 18 months, led the field by five shots heading into the final round and victory would have vaulted him to the top of the world rankings for the first time.

Perhaps that elevated status played on his mind because his 4-over-par 76 saw him slip backwards and set up a dramatic final round rollercoaster ride.

A host of players had a tilt at the elite field title.

Justin Thomas thrashed a 64 which was too little too late - he finished tied fifth with Morikawa.

Patrick Reed and Sam Burns both topped the leaderboard at some point, but back nine errors cost them and they finished in a share of third.

Scottie Scheffler was another to go low, but the win at the top level remains just beyond him - he was solo second.

He posted three front nine birdies to get in the hunt, but the real drama came in the back end of his lap of the Albany course in the Bahamas.

He hold from a bunker for an eagle-2 at the 14th and then followed it with a more conventional eagle-3 at the 15th. A birdie at 16 appeared to have sealed the deal before he gave the field a sniff with bogeys at the final two holes.

However he had done enough to land a fifth career win.

"I didn't think a win was going to be very plausible but I know this golf course is tricky," he said.

"You can make a lot of birdies and make up a lot of ground but it's very easy to make bogeys and doubles.

"I knew if I put a good score up there you never know what is going to happen."
