Jordan Spieth admitted to signing for the wrong score at The Genesis Invitational at Riviera on Friday as the former US Open champion was disqualified for the first time in his career.
The PGA Tour said that the former world No 1 had signed at the end of the second round for a three on the par-three fourth hole when he had made a four.
Spieth’s disqualification was his first in 263 tournaments played on the PGA Tour.
“Today, I made a mistake by signing an inaccurate scorecard and leaving the scoring area, even though I believed I had followed all the necessary steps to ensure its accuracy. This statement was shared by the 30-year-old on X, previously known as Twitter.
“Rules are rules, and I take full responsibility.
“I love this tournament and golf course as much as any on the PGA Tour so it hurts to not have a run at the weekend.”
Tiger Woods will also be missing from the final two rounds of the tournament after the 15-times major champion withdrew on Friday due to illness.
