Phil Mickelson's historic win at the PGA Championship may have been the story of the weekend, but a previously unaired video of second-placed Brooks Koepka has sparked possibly an even bigger reaction from golf fans.
Koepka, who finished two shots behind Mickelson in a tie for second at the majortournament, was questioned about how his second day went and couldn't hide his frustration in an interview after his round.
Add his well-documented fued with Bryson DeChambeau and you get what transpired in the sensational interview, with Koepka dropping several f-bombs and showing utter disdain for his fellow American.
In the clip, Golf Channel reporter Todd Lewis begins questioning Koepka about his second round.
As Lewis was speaking, Koepka appears to be distracted and eventually loses his train of thought as DeChambeau walks behind him in the shot.
It's unclear what DeChambeau said or if it was merely his presence – or the fact that he was wearing steel spikes – that irked Koepka, but it shows how much the two don't really like each other.
The duo's petty feud dates back to January last year, when DeChambeau took a shot at Koepka's physique during a Twitch stream.
"I don't know if his genetics even make him look good, to be honest," DeChambeau said on the gaming streaming platform. "I mean, the Body Issue, he didn't have any abs, I can tell you that. I've got some abs."
Koepka has since fired several light-hearted jabs at DeChambeau, while the big man known as "The Scientist" has stayed comparatively quiet.
DeChambeau does appear to be aware of the recent video, which has gone viral on social media, commenting on Instagram: "You know you can fix spike marks now."
