Jordan Spieth admitted to signing for the wrong score at The Genesis Invitational at Riviera on Friday as the three-time major champion was disqualified for the first time in his career. The PGA Tour said that Spieth 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 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."
