Then, he waited in the trailer to see if anyone could catch him. At one point, he went over to the practice green, but not to prepare for a playoff.

“I probably would have felt sick watching on TV,” he said.

Molinari finished at 8-under 276, the lowest score in eight Opens at Carnoustie, the course where Jean Van de Velde threw away the British Open with a triple bogey on the last hole in 1999, where Padraig Harrington twice hit into Barry Burn on the last hole to make double bogey and still won.

“Just disbelief, to be honest,” the 35-year-old said. “To go the weekend bogey-free, it’s unthinkable. Playing with Tiger was another challenge. But I felt really good this morning. I felt I was ready for the challenge.”

Woods had every reason to believe he would cap a most improbable comeback from four back surgeries.

His red shirt blazing against the yellow grass of a dry Scottish summer, Woods hit driver into the wind on the par-4 fourth to set up birdie. Into the wind on the par-5 sixth, three deep bunkers to the right and out-of-bounds to the left, he got to the front of the green with a driver and a 3-wood for another birdie.

And just like the Woods of old, the players he was chasing started to collapse.

Spieth gambled with a shot to clear the burn on No. 6 and went into a gorse bush, making double bogey. Schauffele chopped up the next hole for double bogey.

Woods had the lead.

And then he lost it with two bad holes. Still in range, he couldn’t get close enough for a birdie when it mattered. It was the first time since the 2007 U.S. Open that he trailed going into the final round of a major, had the lead and didn’t win.

His anger over his mistakes was tempered by perspective, comparing it to Serena Williams losing in the finals at Wimbledon.

“The beginning of the year, if they’d have said, ‘You’re playing The Open Championship,’ I would have said I’d be very lucky to do that. Serena and I are good friends. I’m sure she’ll probably call me and talk to me about it because you’ve got to put things in perspective. ... I know that it’s going to sting for a little bit here, but given where I was to where I’m at now, blessed.”

It might sting even worse for Spieth. One day after a bogey-free round of 65 to share the lead, he had a birdie-free round at the worst time. His best chance was at the 14th, where he three-putted for par from about 40 feet.

“When you put yourself in position enough times, it goes your way sometimes, it doesn’t go your way sometimes,” Spieth said, who goes to the PGA Championship in three weeks for a chance at the career Grand Slam.

The victory adds to Molinari’s best stretch of golf.

Now at a career-best No. 6 in the world, he has won three times and been runner-up twice in his last six tournaments. One of those was three weeks ago at the Quicken Loans National when he shot 62 in the final round and Woods, the tournament host, presented him the trophy.

This round wasn’t flashy, and neither is Molinari. He saved par with 8-foot putts on the 12th and 13th, two of the most pivotal putts all day.

But not the most memorable.

“That putt on the last, I’ll never forget,” he said.
