The PGA Championship got off to a dramatic start at Aronimink Golf Club on Thursday, but not for the reasons Jon Rahm would have hoped. The world No. 20—and the highest-ranked LIV Golf player in the field—found himself in an awkward spot after a moment of frustration took an unexpected turn.

It all unfolded on the par-4 7th hole. Rahm’s approach shot sailed long of the green, and in a flash of irritation, he took an extra swing with his iron through the rough. But what was meant to be a simple frustration swing quickly went wrong: a divot flew from his club and struck a volunteer standing just inside the ropes, hitting them in the face.

The incident was caught on video, and Rahm wasted no time rushing over to apologize. The volunteer, though holding his face, appeared to be okay. "Just out of frustration, I tried to make an air swing, just over the grass, and I wasn't looking, took a divot, and unfortunately, I hit a volunteer," Rahm explained after the round. "It hit him in the shoulder and then the face. I couldn't feel any worse. That's why I was there apologizing."

Despite the rocky moment, Rahm kept his composure on the course. He bogeyed the 7th to fall back to even par but rallied with a hole-out eagle from the fairway on the 2nd hole. He finished the opening round with a 1-under 69, just two shots off the lead and eight straight pars to close out his day.

For Rahm, it was a reminder that even the best in the game can have moments they'd rather forget—but owning up to them with class is what truly counts.
