PINEHURST, N.C. (AP) — Bryson DeChambeau won the U.S. Open on Sunday for the second time with the best shot of his life for another finish on the 18th hole at Pinehurst No. 2 that won't be forgotten — and another heavy dose of heartache for Rory McIlroy.

In a wild final hour of more blunders than brilliance, DeChambeau capped off a week of high entertainment by getting up-and-down from 55 yards out of a bunker, making a 4-foot par putt to close with a 1-over 71.

“That's Payne right there, baby!” DeChambeau screamed as he walked off the 18th green.

Payne Stewart famously made a 15-foot par putt on the final hole in 1999 at the first U.S. Open at Pinehurst No. 2, beating Phil Mickelson by one shot. DeChambeau says he was inspired to go to SMU when he saw a mural of Stewart on campus.

The par putt wasn't as long or as suspenseful as Stewart's in 1999. The celebration was every bit of that. DeChambeau repeatedly pumped those strong arms as he screamed to the blue sky, turning in every direction to a gallery that cheered him on all week.

McIlroy was in the scoring room, devastated by another close call in a major.

This one will sting. As much as this U.S. Open will be remembered for DeChambeau's marvelous bunker shot, McIlroy played a big part by shockingly missing two short putts, the last one from just inside 4 feet for par on the final hole. He closed with a 69.

He had the look of a winner for so long on Sunday, running off four birdies in a five-hole stretch around the turn. He was a model of cool, the opposite of DeChambeau's exuberance.

McIlroy was two shots ahead walking to the 14th tee. The chants grew louder — “Ror-EE! Ror-EE!” and DeChambeau could hear them.

McIlroy took bogey from behind the 15th green, but he stayed one ahead when DeChambeau, playing in the group behind him, had his first three-putt of the week on the 15th when he missed from 4 feet.

And that's where this U.S. Open took a devasting turn for McIlroy.

He missed a 30-inch par putt on the 16th hole to fall back into a tie. On the 18th hole, McIlroy's tee shot landed behind a wiregrass bush. He blasted out short of the green and pitched beautifully to 4 feet. And he missed again.

McIlroy was watching from the scoring room as DeChambeau escaped from an awful lie left of the fairway — a tree in his back swing, a root in front of the golf ball — and punched it out into the bunker. He expertly blasted a shot from the soft sand that rolled out on the crispy green to set up the winning putt.

“I still can't believe that up-and-down,” DeChambeau said as he watched a replay from the video screen during the trophy presentation. “Probably the best shot of my life.”

McIlroy spun his tires in the gravel as he drove away without comment. Since he won the U.S. Open at Congressional in 2011, he has seven top 10s without a victory — it's been more than 100 years since anyone did that well without going home with the trophy.

DeChambeau becomes the second LIV Golf player to win a major, following Brooks Koepka at the PGA Championship last year.

An image of Stewart's famous pose was on the pin flag at the 18th, and DeChambeau put on a Stewart-inspired flat cap during the trophy presentation, later replacing it with his “Crushers” cap from LIV.

He finished at 6-under 274.

Patrick Cantlay lingered around this duel all afternoon, unable to get the putts to fall at the right time until he missed a 7-foot par putt on the 16th hole that ended his chances. He closed with a 70 and tied for third with Tony Finau, who matched a Sunday best with 67 without ever having a serious chance of winning.

Cantlay would have needed a runner-up finish to get the fourth American spot in the Olympics. That goes to Collin Morikawa. Corey Conners closed with a 70 to move past Adam Hadwin and claim an Olympic spot for Canada.

DeChambeau earned $4.3 million — more than he gets from winning a LIV event — from the record $21.5 million purse.

This is not the same DeChambeau who set a scoring record for U.S. Opens at Winged Foot in 2020, a quiet victory because it was during the COVID-19 pandemic and no fans were allowed.

In the sandhills of North Carolina, he had thousands on his side. He signed autographs during his round, he engaged with fans and he delivered one hell of a show.

And when it was over, he looked at the double-decker grandstands around the 18th and thousands circling the 18th green and invited them to his party.

“I want all of you guys somehow,” he said, pointing at them in every direction, “I want you guys to touch this trophy because I want you to experience what this feels like for me. You were a part of this journey this week, and I want you to be a part of it for the after party.”

He picked the perfect place to pose with the trophy — in the bunker short and right of the 18th green, smiling and filling the prize with grains of sand.

DeChambeau wasn't flawless. He hit only five fairways, the fewest in the final round by a U.S. Open champion since Angel Cabrera at Oakmont in 2007. He couldn't escape the trouble on the 12th, leading to a bogey that dropped him two shots behind.

He followed with a 3-wood to the middle of the green on the 316-yard 13th hole, where the tee was moved up, and made birdie to stay in the game. And after his three-putt on the 15th, he wasn't in trouble the rest of the way until the final hole.

That turned out to be his finest moment, certainly the most memorable.

“What's most impressive about Bryson is not that he hits the ball far. Everybody knows it,” said Matthieu Pavon, who played with DeChambeau and shot 71 to finish fifth. “I was amazed by the quality of the short game on 18. It's a master class.”
