Adam Scott costly error at Cadillac Championship as wrong ball confusion triggers Rule 6.3c penalty at Trump National Doral

It only took a small moment to change the round for Adam Scott. During the first round of the 2026 Cadillac Championship, the experienced golfer was given a two-stroke penalty after playing the wrong ball.

The incident happened on Hole 8 at Trump National Doral, a course known for punishing even small mistakes.At first, nothing looked unusual. Scott walked up after his tee shot, saw a ball, and played it. But soon after, it became clear that the ball was not his. According to Nico Pearson, the situation was reviewed, and the decision was simple under the rules. Scott had to take a two-stroke penalty for playing the wrong ball during the round.

Adam Scott’s wrong ball error at Cadillac Championship shows how strict golf rules can be under Rule 6.3c

Pearson explained the moment clearly while speaking during the broadcast. “After his tee shot, Scott thought he was playing his own ball, but it actually belonged to someone else,” he said. Because of that, the shots Scott played with that ball did not count. He then located his real ball, played it from the correct place, and accepted the penalty before moving to the next hole.This mistake was not about a poor swing or a bad decision with the club.

It came down to a quick assumption. Scott believed the ball he saw was his, and he acted on that thought. But golf rules are very clear in such situations. Rule 6.3c focuses only on one thing, whether the correct ball was played.Scott had earlier described the Blue Monster course as “very penal,” and this moment proved his point. Even a simple mix-up can cost a player strokes in a big event. And this is not something new in golf.There have been similar cases before. In 2010, Dustin Johnson received a two-stroke penalty at Whistling Straits after grounding his club in what he did not realize was a bunker. That mistake dropped him out of contention. In 2013, Tiger Woods also faced a penalty at Augusta after taking an improper drop.In all these cases, the players did not break the rules on purpose. But intent does not change the outcome in golf. The rules are applied the same way every time.For Scott, this moment will be a reminder of how careful players need to be, even in situations that seem simple. One quick decision, one missed check, and the cost can be immediate.
