In the first round of the U.S. Open, Joaquin Niemann was knocked with a two-stroke penalty following him allegedly tossing his golf club at least 50 yards amid a horrible showing on the sixth hole where he ultimately scored a septuple bogey.

Tristan Chang, a volunteer for the U.S. Open who saw the incident, spoke to The Athletic and claimed that Niemann requested a relief ruling connected to fire ants close to his ball. After he was issued a denial, Niemann allegedly took to the flag marking the ball and kicked it. Following that, he put a kick into the grass and threw his club at least 50 yards, according to Chang.

“It was a pretty impressive throw, actually,” said Chang, per The Athletic.

The alleged antics from Niemann takes place only months following the four major tournaments agreeing to a fresh policy for code of conduct for the 2026 season.

Per the USGA, severe misconduct is defined as, “If a player’s (or their caddie’s) behavior is so far removed from what is expected in the spirit of the game of golf, in accordance with Rule 1.2b, the Chief Referee, in consultation with the Championship Director, may apply a penalty of two strokes or disqualification, taking account of the frequency, impact, intent and severity of the misconduct,” per Newsweek.

The on-course behavior from Niemann allegedly got to the point where punishment was required. Footage of the incident hasn’t been discovered as of yet.

Niemann, who plays on the LIV Golf circuit, is trying to climb his way back up the leaderboard following a first-round score of 78 that placed him a good distance away from the cut line. In the second round, through the first nine holes he played, Niemann put up five birdies and is four-under in Friday play, while being four-over for the U.S. Open. As a result, that places him only one shot away from the cut, which could potentially shift to four-over later in the round.
