Rory McIlroy had an eventful first round at the BMW PGA Championship, shooting a 5-under 67 despite his 9-iron head detaching mid-swing, which left him momentarily confused but did not affect his shot accuracy. He managed to recover the club and continued to perform well, but a bogey on the final hole cost him a share of the lead. An awkward interaction with 'Spider-Man' actor Tom Holland went viral, suggesting McIlroy did not recognize the Hollywood star. Despite recent close calls at the Irish Open and US Open, McIlroy remains focused and optimistic about his form and upcoming chances.
