Bryson DeChambeau's US Open fell apart at an eventful hole that featured a streaker, a 12-pack of beer, and a slip out of the tee box

• Bryson DeChambeau was leading the US Open heading into his final nine holes.
• DeChambeau collapsed on the back nine, carding two bogeys and a double-bogey in three holes.
• At the 13th, DeChambeau's round truly went to shambles.

Bryson DeChambeau got off to a hot start on Sunday at the US Open and looked like he was in a good position to repeat as champion at the toughest test in golf.

After two birdies on the front nine and some shaky play from others at the top of the leaderboard, DeChambeau worked his way into a share of the lead heading into his final nine holes of the tournament.

It all fell apart.

After back-to-back bogeys at Nos. 11 and 12, DeChambeau needed to bounce back at the par 5 No. 13, but the hole would prove calamitous for the burly golfer.

DeChambeau's problems started at the tee box when his back foot slipped from underneath him in the middle of his powerful drive.

DeChambeau's slip helped send his drive flying wildly wide right, leaving him in the deep rough and eliminating the possibility of reaching the green in two. But his struggles would only worsen from there.

Rather than bailing out into the fairway for an easier approach, DeChambeau tried to power through the course. He sent his next shot further up the right side of the fairway and into deeper rough and his third into a bunker short of the green.

DeChambeau's play was briefly interrupted during this stretch after a fan stormed the course at Torrey Pines with a club and two golf balls in hand and took a few swings.

After being taken down by security, that fan was in for a pretty tough rest of the day, but there's a good chance it still went better than DeChambeau's.

Out of the bunker, DeChambeau sent his fourth shot over the green and into a crowd of fans. His ball settled next to a well-used 12-pack of Stella Artois.

DeChambeau took relief from the spot, chipped onto the green, and two-putted his way to a double-bogey.

After leading the field at 5-under par, DeChambeau had dropped four shots in three holes to play himself out of the tournament.

If there were any beers left in that case, I'm sure he could use one.
