Rory McIlroy has fiercely defended his caddie, Harry Diamond, against criticism following McIlroy's runner-up finish at the 2024 US Open. Critics, including Hank Haney and Smylie Kaufman, argued that Diamond's lack of intervention contributed to McIlroy's collapse. McIlroy responded by highlighting Diamond's role in his numerous victories, stating that the criticism was unfair and that these critics never acknowledge their successes. Despite the US Open setback, McIlroy demonstrated resilience by delivering a strong performance at the Genesis Scottish Open, shooting a 5-under 65 in the opening round. McIlroy remains confident in his game and his partnership with Diamond as he aims for further success.
