ÉVIAN RESORT GOLF CLUB, France — A month ago, Haeran Ryu was dreaming of winning just one major; now the 25-year-old South Korean has won two in 14 days.Ryu’s victory in the Amundi Evian Championship on Sunday after a tense playoff against Canadian Brooke Henderson arrives after winning the KPMG Women’s PGA Championship at Hazeltine National Golf Club in Chaska, Minn., on June 28.Wearing the same yellow shirt, Ryu, whose name “Hae” means “sun” in Korean, put her hand over her mouth, let out a sigh and smiled on Evian’s 18th green. What was only her second birdie of the day had landed her the title, 11 years on from when she won the Amundi Evian Juniors Cup here as an amateur.Her mother, Gumlim Kim, was on the edge of the green applauding as the trophy was placed into her daughter’s hands. The winning putt had sunk in but not much else. Ryu was in disbelief as champagne and Evian water splashed over her.“This is just a dream right now because three weeks (ago) I didn’t have a major championship, but now two in a row,” Ryu said in her TV interview moments after winning. “I’m so happy and I can’t believe it.”Ryu said it felt like a “fake cartoon.”“It’s an unreal dream right now. There’s a lot of great names on the trophy, and I so happy my name is on here,” she said, looking down to check it again.Haerun Ryu, right, and her mother, Gumlim Kim, celebrate with the Evian Championship trophy.

That 11-under-par day placed her three shots ahead of Japan’s Aki Iwai, who led after Round 1, and seven shots in front of Henderson. But during the final round, Ryu could not get her putts to drop while the two golfers in her company did.The pressure ramped up with a bogey on No. 8 as Henderson grabbed the only hole-in-one of the weekend. As soon as birdie chances came, they went for Ryu, who hit 16 pars.Her caddie of four years, Martin Bozek, had a clear message throughout a testing round. He reassured Ryu her putting was fine and to stop worrying about the lack of birdies.“It was just a battle all day,” Bozek, also dripping in champagne, told The Athletic on the 18th green. “Even though we had a little bit of a lead starting the round, it’s hard to come back and play after shooting 60 on the Saturday and she did great, she stayed there.”By the 17th hole, both Iwai and Henderson had chased down Ryu to share the lead. A bogey momentarily dropped Henderson back. A shot into the rough on No. 18 left Ryu scrambling to make birdie, with Henderson about to grab her second eagle of the day to set up the playoff. Iwai’s race was run as a par was not enough to take her into the antics of an extra hole.“It was just a matter of having that one putt fall, and it fell on the 18th hole,” Bozek said. “That was the one that mattered, and I was proud of her. She stayed in it, never got too down and got it done.”Bozek says a five-week hiatus earlier in the year to deal with a minor injury setback helped give Ryu the rest not usually afforded to professional golfers. “She came back fresh and had a lot of momentum,” he said.Caddie Martin Bozek, center, said Haeran Ryu has been steadily working to this moment for years.

As Henderson found the rough twice on her playoff approach, Ryu kept her cool in the relentless sunshine, found the fairway and got down in four shots on the par 5. After waiting over five hours to make one birdie, another closely followed. That seems to be a recent theme for Ryu, who will go into the AIG Women’s Open at Royal Lytham & St. Anne’s in northwest England in two weeks, looking to land an improbable third major in five weeks.It was world No. 1 Nelly Korda, who did not make the cut this weekend, who wrapped up the first two majors of the year with wins at the Chevron Championship and U.S. Women’s Open. The question now is whether Ryu can go on to dominate in a sport where the majors are often shared around each season.“I think so,” Bozek, who left the course looking forward to a few drinks in Geneva, Switzerland, said. “She just needs to know she’s as good as anybody out here, as good as Nelly. And I think she’s getting that confidence, she’s starting to realize that. The more time she gets in these positions the more comfortable she’s going to be. You can’t have that mindset unless you experience it.“That was the biggest thing in the first few years of working together, understanding what pressure was, playing with the best in the world in a final group at a major. She’s learned, she’s learning and it’s just getting easier.”Stage 16 of the Tour de France will pass through Évian-les-Bains later this month, but it was the yellow jersey of Ryu, whose Instagram bio reads “the sun shines everywhere”, that has already lit up this quiet town. One of her traditions is to add a sunshine to her golf bag every time she wins a tournament. And now, after another surreal weekend, she has one more to add to what is a fast-growing collection.
