For a moment, it looked like the reigning U.S. Open champion would make it a second straight title.
Bryson DeChambeau shot a birdie on the par-3 eighth hole during the final round to put him at 5-under par and move him into the lead with 10 holes remaining. It all fell apart from there.
Bogeys on both the 11th and 12th holes, and a double-bogey and quadruple-bogey in the 13th and 17th holes, respectively, sunk DeChambeau's chances of winning, ultimately leading to him falling to 3-over during the U.S. Open and tying for 26th overall.
After the disappointing finish, DeChambeau said that it wasn't a poor effort on his part, but rather a product of bad luck.
"I didn't get off the rails at all. It's golf," DeChambeau said, according to the Golf Channel. "People will say I did this or did that, and it's just golf. I've had plenty of times where I hit it way worse than today and I won. It's just one of those things where I didn't have the right breaks happen at the right time."

On the 13th hole, he slipped on the drive to slice the ball into the right rough before later slipping again trying to save himself from too much damage on the hole. It resulted in a double-bogey seven that all but took him out of the running for the championship.
The struggles on the 13 came right on the heels of a pair of bogeys.
Later, on the 17th hole, his tee shot hit the ravine and his third shot sailed into a bunker. He overshot out of the bunker and sank to an 8 on the par-4 hole.
"I hit a great second shot -- well, third shot, and the ball just spun too much," DeChambeau said, according to ESPN. "The wind died down and it landed short and came back off of that front edge into a really, really bad lie. I tried just chopping it out, and I caught the hosel just from a weird line."
Perhaps even worse for DeChambeau was that when he was leading, rival Brooks Koepka was just a shot behind him. When it was all over, Koepka remained tied for fourth at 2-under for the tournament.
But DeChambeau said he wasn't worried about his lackluster performance down the stretch.
“Right now, I don’t even care. I’ve changed a lot, attitude-wise and everything," DeChambeau said, according to the New York Post. "It’s frustrating in the moment when it’s happening, but afterwards for me now, I don’t really care as much. I’ve already won [a U.S. Open].’’
