From ball kicks to slow-play warnings, we look back at the quirkiest and most memorable golf moments of the year.
Not only in amateur play, but also in professional golf, there are often exciting incidents related to the rules. At the end of 2025, we review some of the biggest blunders and most intriguing rule violations in professional golf. This year featured several outstanding scenarios where players faced novel situations, resulting in varying consequences from officials.
Bud Cauley Steps on Ball but Faces No Penalty Thanks to Rule 9.6
During the final Sunday of the 2025 Players Championship, amidst a long weather delay, an unusual moment occurred when Bud Cauley accidentally stepped on fellow competitor Lucas Glover’s ball. According to Rule 9.6, movement of the ball caused by external factors is without penalty, allowing Glover to replace his ball to its original spot. This incident highlights distinctions in rules: balls moved by natural forces usually must be played from their new location, but a ball already placed on the green must be replaced regardless of what caused it to move.
Shane Lowry’s Rule Mistake at US Open Ends with Humor
In the second round of the 2025 US Open at Oakmont Country Club, Shane Lowry committed a rare rule infraction by picking up his ball on the 14th green without marking it first, violating Rule 14.1 and incurring a penalty stroke that turned the hole into a double bogey. Despite missing the cut, Lowry laughed off the error, calling it one of the dumbest things he’s done. Fellow player Rory McIlroy also reacted with laughter. Lowry marked the ball correctly afterward and continued playing with determination.
Other Notable Moments: Self-Disqualification, Slow Play Warnings, and DP World Tour Incident
US pro Hannah Gregg self-disqualified at the 2025 Amundi German Masters after signing for a score lower than actually played on the 14th hole, per Rule 3.3b(3). Her honest admission earned praise on social media. Slow play became a focal point early at the British Open, with players like J.J. Spaun receiving an official warning for exceeding allowed shot times, increasing pressure in the cut fight. On the DP World Tour, Marcel Siem faced a disqualification after playing a provisional ball incorrectly on the 18th hole, an unintentional but costly mistake. These moments remind us how crucial understanding and adhering to golf’s intricate rules remain at the highest levels.
