SOUTHPORT, England — Sam Burns gets his best chance at winning a major he never planned to play.Two weeks after his daughter was born, one week after Burns changed his mind and decided to fly from Louisiana to play in the British Open, he followed his record-tying 62 with a 5-under 65 on Saturday to build a two-shot lead at Royal Birkdale.Perhaps even more impressive was he played with purpose amid the chaos that is Bryson DeChambeau, who played alongside Burns and heard big support from the gallery a day after he theatrically protested a two-shot penalty for improving the path of his swing.DeChambeau seems to thrive among distractions — his week began with six-time major champion Nick Faldo saying he had “zero clue of strategy” in links golf — and the penalty for an infraction on the fifth hole Friday was a big one. The two shots took him out of the final group and moved him three shots behind instead of one back.But he pressed on, high-fiving the gallery from green-to-tee, giving a thumbs-up to the crowd when he walked onto the first tee and playing a high standard of golf. DeChambeau was even par through 14 holes until two birdies gave him momentum. He bogeyed the last hole for a 69, his sixth consecutive round in the 60s in the British Open.DeChambeau didn’t speak to the media again. Rory McIlroy did, referring to the way DeChambeau protested the penalty as “performative.”“I think a lot of it’s for attention,” McIlroy said after a 69 left him eight shots behind. He also accused DeChambeau of holding the tournament “hostage” because the extraordinary late-evening scene also delayed Saturday tee times.The golf attention now falls to Burns.He was at 10-under 200 for a two-shot lead over Si Woo Kim (67) and Ryan Fox, who became the third player this week to tie the major championship record with a 62. He finished some 90 minutes before the last group even teed off, and now the 39-year-old from New Zealand will be in the final group with a shot at his first major.Burns shot d …
