Joaquín Niemann is penalized after throwing his club during the first round of the 2026 U.S. Open at Shinnecock Hills, with the U.S. Golf Association citing the act as “serious misconduct” under Rule 1.2b. According to multiple reports, the penalty assessed is two strokes. Niemann disputes the penalty severity, telling reporters that he believes he is “not proud” of the misconduct but that the punishment was excessive or “extra-penalized.” Despite the penalty, he responds on the course by playing a second round of 5-under 65, which enables him to make the cut. The outlets describe the incident as a significant rules violation rather than a minor infraction, and they frame Niemann’s subsequent remarks as a balance between acknowledging wrongdoing and challenging how the penalty is applied. The USGA ruling stands as the official disciplinary outcome for the club-throwing episode.
