Bryson DeChambeau was involved in an angry altercation with a fan after losing a tense sudden death playoff to Patrick Cantlay in the BMW Championship, according to a report from ESPN.
According to the report, a patron yelled "Great job, Brooksie" from the rope-line, a taunt the golfer had been hearing throughout the tournament.
The chant references DeChambeau's ongoing feud with Brooks Koepka.
"You know what? Get the f--- out!" DeChambeau yelled, with ESPN reporting "he had rage in his eyes."
The encounter lasted less than 10 seconds as DeChambeau motioned for security to deal with the patron and continued toward the clubhouse at Caves Valley Golf Club in Owings.
Patrick Cantlay made a litany of clutch putts, culminating in a 17 1/2-footbirdie on the sixth playoff hole that carried him to the victory.
DeChambeau missed four putts that would have won the tournament - the 72nd hole and each of the first three playoff holes.
DeChambeau and Cantlay also had their own interaction during the round.
DeChambeau, when preparing to hit his shot from the fairway, asked Cantlay to stop walking.

"He just wanted me to stop walking," Cantlay told Golf Digest.
"We had just been told by the rules officials to kind of speed up, and I'm not always the fastest walker, so I was trying to get ahead and do my part. No big deal. That stuff kind of happens every once in a while out here."
