MEMPHIS, Tenn. — Hideki Matsuyama could feel the tournament getting away from him, an odd sensation considering he had gone 27 holes without a bogey and had a five-shot lead just an hour earlier.

Even more improbable was how it ended Sunday.

On the verge of a collapse, Matsuyama rolled in a 25-foot birdie putt on the 17th hole to regain the lead and then hit two shots as precise as any he hit all day for one last birdie to win a wild PGA Tour postseason opener at the FedEx St. Jude Championship.

Birdies on the final two holes – among the toughest at TPC Southwind – gave the Japanese star an even-par 70 and a two-shot victory over Xander Schauffele and Viktor Hovland, who thought they were playing for cash and FedEx Cup points until Matsuyama’s mini-meltdown.

A three-putt bogey on the 12th. A tee shot into the water on the par-3 14th, where Matsuyama did well to escape with bogey. Two chips to reach the 15th green, resulting in a double bogey. When he saw a leaderboard on the 16th hole, it confirmed what Matsuyama feared.

“I felt today’s victory slipping away at that point because 17 and 18 are difficult holes enough, let alone to birdie them,” Matsuyama said through his interpreter.

He birdied them both for his 10th PGA Tour victory and first in the FedEx Cup playoffs.

The stakes suddenly were high for everyone in the final hour of what had been a sleepy, steamy tournament. It was tight at the top, and just as tense on the bubble to determine the top 50 players in the FedEx Cup standings who advanced to next week.

How tense?

Consider Nick Dunlap, who went from a chance to win the tournament to needing his best drive of the week just to stay in the top 50 in playoff points and extend his season. He was as clutch as Matsuyama off the 18th tee, closing with a par for a 69 to tie for fifth.

“It was weird,” Dunlap said. “I went from on 17, I tried to attack the pin. I thought I still had a chance to win the golf tournament. Then not getting up-and-down, and then I’m questioning if I’m inside the bubble or not. It was very stressful.”

Tom Kim looked certain to finish in the top 50 until a 6-6-6 finish ended his season.

Schauffele started nine shots behind but shot a 63 and waited to see if he would get into a playoff. Hovland had a one-shot lead with two holes to play. Scottie Scheffler, who shot 66 and finished fourth, was still in contention on the 17th hole.

Ultimately, it came down to Matsuyama.

The collapse was stunning. So was the response.

“He just never seemed to let it get to him. It was really impressive,” said Dunlap, who played in the final group with Matsuyama. “That’s why he’s got a green jacket and a ton of other things. It was definitely cool for me to watch. He deserves it. He was impressive all day.

Hovland, the defending FedEx Cup champion, began the postseason at No. 57, without a guarantee he would be able to defend his title in the BMW Championship next week. And then he had a chance to win, taking the lead with his birdie on the 16th. He gave it back by failing to save par from a bunker on the 17th, and then he missed a 9-foot birdie putt on the 18th, settling for a 66. That was good enough not only to play next week, but to lock up a spot in the Tour Championship.

Matsuyama, who finished at 17-under 263, won for the second time this year. The Olympic bronze medalist earned $3.6 million and moved from No. 8 to No. 3 in the FedEx Cup standings.

It was quite a week for the Japanese star, who had to find a fill-in caddie and could only work with his coach over the phone. All of them were out to dinner in London on their way home from the Paris Olympics when someone stole their bag when they weren’t looking.

The thief got Matsuyama’s wallet and the passports of his caddie and coach. They had to return to Japan and work on getting expedited replacements. Matsuyama pressed on like it was another work week and came up with his first postseason victory.

Hovland, Dunlap and Eric Cole moved into the top 50. Cole did it in style with a 63, despite a bogey on the closing hole. Kim, Mackenzie Hughes and Jake Knapp fell out of the top 50.

Kim was poised to advance until it took him two shots to get out of a greenside bunker on the par-5 16th (bogey) and two chips to get to the green on the 17th (double bogey), followed by a tee shot into the water on the 18th (double bogey).

“This season has just been … it’s just been like this,” Kim said. “I’ve played really good golf, and then had some tough finishes. I feel like 2024 has really kicked me in the butt.”
