ARDMORE, Pa. — Jack Whaley of England will face Jay Leng Jr. for the U.S. Amateur title at Merion Golf Club after a semifinal Saturday that tested nerves and resilience. Whaley, a senior at Florida State, twice squandered 3-up leads against Georgia senior Carter Loflin but summoned a clutch 5-foot bogey putt on the 18th hole to secure a 1-up victory. The win sends Whaley, ranked 90th in the World Amateur Golf Ranking, into the championship match against Stanford junior Jay Leng Jr., who never trailed in his 2-and-1 win over Auburn sophomore Logan Reilly.

Leng, ranked 23rd, displayed grit despite not having his best game. He made only two birdies all day — the first on the par-3 10th and another on the 15th, where he hit a wedge to 5 feet to go 2-up. The match turned on the 12th when Reilly, having a chance to square the match, saw his approach shot hit the pin and roll off the green, into the fairway and into the rough, leading to a bogey that put him 2-down. Leng closed out the match on the 17th with a par. “I didn't have my best stuff today,” Leng said. “Coming down the stretch I kept thinking about how good I've been playing this summer.” He has not trailed in his last 42 holes, dating back to the sixth hole of his round-of-16 match against third-ranked Tyler Watts.

Whaley’s path was far more turbulent. He built a 3-up lead twice, only to see Loflin rally each time. The match reached the 18th hole all square. Merion’s 18th, notorious for its sloping fairway and false front on the green, produced drama. Both players found the rough and came up short of the green. Loflin’s lob wedge over the false front took a big hop and rolled over the green into thick grass. His chip left him about 12 feet for par, and he missed the bogey putt. Whaley’s pitch ran out 45 feet, barely staying on the green. He lagged to 5 feet and calmly rolled in the bogey putt to win. “I felt like I closed my eyes and hoped for the best,” Whaley said. “I'm absolutely over the moon.”

Both finalists have already earned spots in the Masters and the U.S. Open at Pebble Beach next year, provided they maintain amateur status. Whaley is trying to become the first English amateur to win the U.S. Amateur since Matt Fitzpatrick at Brookline in 2013. Leng, who has been in fine form this summer, said of his semifinal: “I'm still speechless right now. It will take at least until tonight to sink in.” The championship match Sunday will feature two players with contrasting paths — one steady, one resilient — at the historic Merion layout.
