Rory McIlroy Finds a Brotherly Bond Beyond Blood

Rory McIlroy and his caddie Harry Diamond strengthened a relationship that helped secure the 2025 Masters at Augusta National. Their connection began in childhood on the putting green at Holywood Golf Club.

Early friendship

They met as kids at Holywood Golf Club. Diamond was two years older and befriended McIlroy.

The pair grew close over years of playing together. They later served as best men in each other’s weddings.

A partnership under scrutiny

McIlroy hired Diamond after firing JP Fitzgerald in 2017. What began as a temporary arrangement became permanent.

Many in the golf world blamed Diamond when McIlroy failed to win majors. Diamond had been on McIlroy’s bag for nine years.

He rarely grants interviews, offering only a couple in that span. He largely chose not to publicly defend himself against criticism.

Turning point at Augusta

At the 2025 Masters McIlroy missed a regulation putt on the 18th hole that would have won him the green jacket. The miss sent the match to a playoff.

On the ride back to the 18th tee, Diamond calmed McIlroy with a simple reminder. He told him they would have gladly taken a playoff at the week’s start.

McIlroy recovered and won in the playoff at Augusta National. The victory felt like a triumphant return for both men.

Emotion and perspective

McIlroy became visibly emotional during his victory press conference. He choked up when describing Diamond’s role in his life.

In a subsequent documentary, McIlroy said Diamond was the first person he looked at after sinking the winning putt. He has described their connection as a brotherly bond that feels beyond blood.

McIlroy, an only child, said Diamond is “the big brother I never had.” That sentiment explains why questions about Diamond often move him.
