We saw it all during the final day at Torrey Pines. Implosions. Fireworks. A ball in a tree and a Bryson DeChambeau quadruple-bogey. But perhaps the weirdest and wildest highlight of the afternoon was the one you didn’t see (a running theme with the TV coverage, it seems).

With DeChambeau and Scottie Scheffler’s group having just teed off on the par-5 13th, a barefoot fan in a rainbow cape leapt inside the ropes and went running down the middle of the fairway, club in hand. Pulling his own golf balls from his pocket, he aimed left and let fly. To the surprise of just about everybody, the rogue contender actually had a pretty damn good swing.

Of course, you’re not allowed to bring your own sticks to the US Open, and thus security was quickly on the scene to subdue the intruder.

The “unruly gentleman”, as ‘Bones’ McKay referred to him, is allegedly YouTuber Connor Murphy, who burned his way into the golf consciousness when he wore a rainbow ensemble and fired a 108 at a Korn Ferry Tour qualifier in April. There he proclaimed that he was going to “win the US Open!”. As it turns out he didn’t – in fact, nobody seemed especially eager down the stretch – but he left his mark all the same. After the distraction, DeChambeau double-bogeyed the hole, leaving his US Open defence on life support.
