Bryson DeChambeau received a two-stroke penalty during the second round of the 2026 Open Championship at Royal Birkdale Golf Club in England [1, 2].

The penalty creates a significant swing in the leaderboard during a major championship where every single stroke can determine the final winner. Because the incident occurred during the second round, it affects DeChambeau's momentum and positioning heading into the weekend.

Officials ruled that DeChambeau breached Rule 8.1b by improving his stance or trampling the grass behind his ball [3, 4]. The ruling suggests that the golfer unintentionally altered the surface of the course to gain an advantage, which is prohibited under the rules of golf [4, 5].

DeChambeau, a two-time major champion, expressed frustration following the decision [1, 2]. The penalty of two strokes [3] was added to his round after he had already performed strongly in the early stages of the tournament.

In the opening round, DeChambeau posted a score of 67 [1]. He continued his strong play in the second round with a score of 66, which is four-under par [1]. Despite the penalty, these scores keep him in contention as the field navigates the challenging conditions at Royal Birkdale.

Responding to the controversy and the officials' decision, DeChambeau said, "Fires me up" [6].

The incident has sparked debate among fans and analysts regarding the strict interpretation of Rule 8.1b, a rule that often leads to controversy when the improvement of the lie is deemed unintentional by the player.

This penalty highlights the rigid nature of golf's rules regarding the 'improvement of a lie,' where even unintentional actions can lead to severe scoring penalties. For DeChambeau, the two-stroke addition tests his mental resilience and ability to recover in a high-pressure environment, while the controversy may prompt further scrutiny of how Rule 8.1b is applied consistently across the field at Royal Birkdale.
