ST. LOUIS — Wyndham Clark is making Bellerive look like a practice round. For the second day in a row at the BMW Championship, the 2023 U.S. Open champion posted a bogey-free 6-under 64, pushing his total to 12-under 128 and giving him a one-shot lead over Gary Woodland as the tournament heads into the weekend. Clark has been nearly flawless, the only real test coming Thursday on the 10th hole, where he needed an 18-foot putt to save par. Other than that, he has cruised. “I feel really comfortable with my game,” Clark said. “The course suits my eye, and I’m just trying to keep the pedal down.” But the crowd at Bellerive may not be entirely on his side. Woodland, who grew up about four hours away in Kansas City, has drawn strong support from the Missouri faithful — a rare case of a Kansas native getting love in the Show-Me State. And Woodland’s story adds layers of emotion. He is still coping with side effects from brain surgery in 2023 and is fighting to secure a spot in the Tour Championship. Currently ranked 31st in the FedEx Cup standings, he needs to finish inside the top 30 to advance to East Lake. Woodland birdied his final two holes Friday, crushing a 2-iron into the 608-yard 17th and then sticking a wedge to 8 feet on the 18th for a 65. After his tee shot on 18, he sat down on the fairway. “I’m tired,” he said with a grin. “My focus is one day at a time. I don’t have the luxury to look ahead.” His post-round routine is deliberate: sit in a cool, dark room, let his brain reset, and conserve energy for the next day. J.J. Spaun celebrated his 36th birthday with a 66, leaving him two shots back at 10-under. Sungjae Im shot a 64 and sits three behind, while Patrick Cantlay (65) and Michael Thorbjornsen (66) are four back at 8-under. Scottie Scheffler, still recovering from an illness that has left him speaking quietly and quickly, managed a 65 but lost ground on Clark. He trails by nine shots. Rory McIlroy struggled to just two birdies in a 69 and is five strokes back. Clark, ranked No. 5 in the FedEx Cup, has no such worries about his postseason status. He already has a win at the U.S. Open and a dominant victory at The CJ Cup Byron Nelson. But he got a reminder last month about the dangers of stepping outside his lane. During the Rocket Classic, he was asked to throw out the first pitch at a Detroit Tigers game. He warmed up for 20 minutes, felt good, and decided to throw a little harder. The pitch was perfect — right down the middle. The next morning, his arm was sore. “I woke up and, oh my gosh, my arm was hurting,” Clark said. He missed the cut at the Rocket Classic, but he bounced back with a tie for fifth at the playoff opener in Memphis, and now he’s in prime position at Bellerive. Woodland, who led the 2018 PGA Championship at this same course after 36 holes before fading, knows the challenge ahead. But he feels the energy from the crowd and the comfort of being close to home. “I feel very comfortable. It’s nice having so much support out here,” he said. “The fans have been amazing. I’m definitely feeding off that energy.” With two rounds to go, the BMW Championship has all the ingredients for a gripping weekend: a red-hot Clark, a resilient Woodland backed by a home-state crowd, and a pack of hungry contenders chasing the lead.
