Michael Thompson birdied two of the last three holes on Sunday to claim a two-stroke victory in the 3M Open, finishing off his second PGA Tour win seven years after his first.
Thompson carded a final round four-under 67 and finished at 19-under 265 at TPC Twin Cities.
Adam Long fired a 64 to hold the clubhouse lead but eventually had to be content with second.
Richy Werenski, who shared the lead with Thompson after both Friday and Saturday, had a 70 to end the week in a nine-way tie for third at 16-under.
Tony Finau finished in that group after a 68. He was the only one among the five world top-30 players in the field to reach the weekend, far outperforming Dustin Johnson, Brooks Koepka, Tommy Fleetwood and Paul Casey.
Australian Cameron Davis had four birdies and a bogey to close with a 68 and finish at 14-under in a share for 12th.
The 25-year-old has had two top-10 finishes this year and added US$127,050 (AU$180,000) to his earnings – to take his season's prize money beyond US$675,000 (AU$950,000).
“It has been a long time. I'm really sad my wife and kids aren't here to celebrate this with me. I can't wait to see them.” – Michael Thompson
Nobody throughout the windy and muggy week in Minnesota was steadier than Thompson, who rocketed up to 39th in the FedEx Cup standings on the way to Tennessee for the World Golf Championships event.
He deftly steered around the water danger on the 18th, landing his approach on the back of the green within 15 feet.
With Long in the clubhouse, having played five groups ahead, Thompson had two putts to win.
The 35-year-old needed only one, bending backward and thrusting both of his arms straight up in the air after the ball dropped in the cup in a celebration subdued a bit by the absence of spectators due to the pandemic.
"It has been a long time," an emotional Thompson said.
"I'm really sad my wife and kids aren't here to celebrate this with me. I can't wait to see them.
"Babe, I love you."
For this win, Thompson took home US$1.188 million (AU$1.7m) and secured his future on Tour for two years.
Plus he is eligible to compete at next month's US PGA Championship in San Francisco.
"That's what makes this game so unbelievable is that we have to play for our job every year," he said.
