Sepp Straka knew early on that precision at Philadelphia Cricket Club was the key to the Truist Championship.

Now, the Austrian and the oldest country club in the United States are linked forever.

Straka seized the lead with a par on the 16th hole and shot a 2-under 68, outdueling Shane Lowry on Sunday for his second victory of the season.

“It’s huge, the biggest win of my career,” Straka said of his fourth PGA Tour title.

After Lowry missed the green with his tee shot at the 212-yard, par-3 16th, Straka hit to approximately 30 feet. Lowry chipped out of the heavy rough but failed to convert a 6-foot par putt, falling a shot behind.

Lowry missed a potential tying 22-footer for birdie at the par-4 17th and after driving into trouble at the stout 514-yard, par-4 closing hole, he finished with a three-putt bogey.

A back-nine duel had an anticlimactic ending. Straka made a no-pressure, two-putt par at 18 and joined Rory McIlroy (three victories) as a multiple winner this season. The Austrian who played college golf at Georgia also won The American Express in January.

“It’s not the best ball-striking week I’ve had,” Straka said. “Off the tee the first two days, I hit it terrible.”

The difference, he said, was putting. He made more than 110 feet of putts in the final round.

“The putter was just excellent this week. ... Made a lot of mid-range putts, and that’s something you have to do when you want to win a golf tournament.”

Straka moved to No. 2 in the FedEx standings, gets $3.6 million of the $20 million purse in the PGA Tour’s sixth signature event of the season and takes home the winner’s cricket bat trophy, a nod to the group of students and cricketeers from Penn who founded Philly Cricket in 1854.

He’s poised to move into the top 10 in the world ranking and all but certain to make his second European Ryder Cup team.

Lowry’s even-par 70 left him in a tie for second with Justin Thomas (67), who made a late run at the leaders.

Patrick Cantlay (65), Jacob Bridgeman (65) and Tommy Fleetwood (65) finished tied for fourth at 12 under.

Ryan Fox of New Zealand chipped in from just outside 50 feet on the first playoff hole to win the Myrtle Beach (S.C.) Classic for his first PGA Tour title, sending him back to the PGA Championship.

Fox closed with a 5-under 66 that looked like it might not be enough when Mackenzie Hughes came to the 18th hole with a one-shot lead.

Hughes pulled his drive into the trees, had to pitch out and missed a 10-foot par putt for a 67 that put him in a playoff at 15-under 269 with Fox and Harry Higgs, who missed a 25-foot birdie putt on the 18th with a chance to win for the first time. Higgs shot 68.

Going back to the 18th for the playoff, Hughes and Higgs found the fairway and each had decent looks at birdie. Fox went from the rough to the collar right of the green. He raised both arms when the chip dropped for birdie.

Higgs and Hughes each missed their birdie putts.

The 38-year-old Fox had won three times on the European tour, including the flagship BMW PGA Championship in 2023, and has climbed as high as No. 23 in the world. But he had yet to record a top 10 on the PGA Tour this year.

LPGA Tour

Jeeno Thitikul of Thailand turned back a pair of challenges and played bogey-free over the final 27 holes at Liberty National, closing with a 3-under 69 for a four-shot victory over Celine Boutier (72) in the Mizuho Americas Open in Jersey City, N.J.

Thitikul, who captured the Race to CME Globe and its $4 million prize to end last season, won for the first time this year and the fifth time in her LPGA Tour career.
