Spieth takes responsibility for Genesis Invitational disqualification.

Jordan Spieth admitted to signing for the incorrect score at The Genesis Invitational at Riviera on Friday, and the former US Open champion was disqualified for the first time in his career.

The PGA Tour stated that the former world number one signed at the end of the second round for a three on the par-three fourth hole after making a four.

Spieth's disqualification marked his first in 263 PGA Tour tournaments.

"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," the 30-year-old wrote on X, formerly 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 miss the tournament's final two rounds due to illness, as he withdrew on Friday.
