The Northern Irish golfer criticized Bryson DeChambeau’s actions at the major championship in Southport, England. McIlroy called a penalty against DeChambeau "pretty obvious". McIlroy later offered an olive branch to DeChambeau to his Irish Open stop, despite ongoing tensions. New Zealand's Ryan Fox secured the title with a last-par taker at Royal Birkdale. Fox set a temporary record that another competitor later surpassed with a 54-hole lead during the event. Cameron Young topped the scoring chart as the day’s clubhouse starter at the Open.
