It’s a rarity in your Sunday foursome, let alone the Friday of The Masters.

But there was Zach Johnson on the 13th tee on Friday, preparing to hit his tee shot, when one of his practice swings accidentally hit the ball. The 2007 Masters champ let out an “Oh, s–t” after contact and turned to playing partners Matt Kuchar and Ian Poulter to find out what the protocol was.

Both players ruled the contact incidental and Johnson, who finished at 3-over, would not be given any penalty, and he would go on to birdie the hole.

Still, the announcers on CBS’ livestream both had to admit: “I have never seen that.”
