Jordan Spieth signed for the wrong score on Friday at the Genesis Invitational and was disqualified for the first time in the 263 tournaments he has played on the PGA Tour.
Spieth owned up to the mistake in a post on X.
“Today, I signed for an incorrect scorecard and stepped out of the scoring area, after thinking I went through all procedures to make sure it was correct. Rules are rules, and I take full responsibility,” he wrote.
