American golfer Bryson DeChambeau receives a two-stroke penalty following a rules incident in his second round at The Open Championship. Multiple outlets report that the decision comes after officials review an episode on the fifth hole at Royal Birkdale, where DeChambeau is found to have improved his lie in thick rough during what was described as an intended backswing. BBC Sport adds that the ruling is reached after a lengthy review and results in his score being revised to a triple-bogey seven on the fifth hole. The penalty changes his standing: one report says it drops him from second place into a position further off the lead, leaving him around a three-shot gap from the top. Other coverage notes that the ruling sparks anger from DeChambeau, with some reports saying he threatens to quit the British Open amid the controversy, though the penalty itself is consistent across sources. Overall, outlets agree the two-shot penalty is imposed after a rules breach involving the lie on the fifth hole and a subsequent official ruling that revises the score and affects his position on the leaderboard.
