Woods said his back began to spasm over the final few holes in the Genesis Invitational at Riviera. He said that’s what led to his 8-iron from the middle of the 18th fairway that shot off at a 45-degree angle into the eucalyptus trees.

“Oh, definitely I shanked it,” Woods said. “My back was spasming the last couple holes and it was locking up. I came down and it didn’t move and I presented hosel first and shanked it.

It was no less shocking for the 48-year-old Woods, even at this stage in his career when his back and legs have gone through more surgeries than he has won majors (15). Woods couldn’t recall the last time he hit a cold shank — basically hitting the ball anywhere except on the clubface — except for making some imaginative flop shots around the green.

At least he put it behind him quickly. His shank was behind some eucalyptus trees that frame the right side of the fairway. The shot called for the same club he had just shanked — 8-iron — for a low punch between the trees. And it came out beautifully to 15 feet.

“I had a small window there and tried to hit a punch-hook 8-iron after I just shanked an 8-iron,” he said. “I said, ‘All right, the next shot is supposed to be the harder shot.’ And yes, it was because I’m having to hit a little punch hook through a little gap there.

“And I pulled it off, which is good.”

He still missed the putt and had to settle for a 1-over 72, leaving him eight shots behind Patrick Cantlay and needing to play better on Friday if he wants to stick around for the weekend and wear his new Sun Day Red apparel for golf and not just the trophy ceremony.

Tiger Woods has used his traditional choice of wearing red in a tournament’s final round as influence for a new venture following his split with Nike.

The move follows the 48-year-old ending a partnership of more than 27 years with the sportswear giant in January.

The logo for Sun Day Red features an abstract tiger, made up of 15 stripes, the number of majors he has won.

“Every single tournament I’ve played as a professional I’ve worn red. It’s just become synonymous with me,” said Woods.

“Sunday red – it’s me. It started with mom [Kultida]. She thought being a Capricorn that my power colour was red, so I wore red as a junior golfer and I won some tournaments.

“Lo and behold, I go to a university that is red, Stanford is red. We wore red on the final day of every single tournament.”

Woods is set to play his first PGA Tour event of 2024 at the Genesis Invitational, which starts in California on Thursday, 15 February.

The former world number one underwent ankle surgery in April last year after withdrawing from the Masters during the third round. He did not compete again until the Hero World Challenge in December and has said he expects to play one event per month in 2024.
