According to AOL, the two grew up together in Northern Ireland and have been friends for many years. Their friendship goes back to school days, long before McIlroy became a global sports star. When McIlroy needed a trusted caddie in 2017, he turned to Diamond, who has been by his side ever since.
From McIlroy’s friend to caddie
Before becoming McIlroy’s caddie, Diamond was a talented golfer himself. He even represented Ireland as an amateur player. That background gave him the skills and knowledge to step into the demanding role of being on McIlroy’s team.
As per Golf Monthly, caddies in golf are more than just bag carriers. They offer advice on club selection, distances, and strategy. But for McIlroy, the most important factor was trust. “I was an only child, and Harry was a big brother. We’re very close," he told the publication.
