Who is Rory McIlroy's caddie? Harry Diamond chasing first major win on bag since 2017 change

Rory McIlroy came out of the first day of the PGA Championship on fire and ended five-under and a one-stroke lead over Will Zalatoris. McIlroy, who won the PGA Championship and The Open in 2014, is seeking his first major win with caddie Harry Diamond, who has been with McIlroy since 2017.

Since joining forces in what was initially thought to be a stopgap partnership after McIlroy parted ways with J.P. Fitzgerald. For context, McIlroy made the switch with a ‘guilty conscience’ after the Irishman said he was being ‘very hard’ on Fitzgerald. “I wasn’t playing the best and was frustrated at myself and taking it out on him.”

Diamond took the bag after Fitzgerald and has been a part of McIlroy’s seven wins and two Ryder Cup wins since.

The pair’s relationship, however, goes well beyond golf. Here’s what to know about Diamond as he looks for his first major win as McIlroy’s caddie.

Why did Rory McIlroy pair with Harry Diamond?

They say not to work with your friends, but McIlroy and Diamond to this point have disproven that adage. The two joined up after McIlroy parted ways with Fitzgerald, but their relationship runs deeper than golf.

“I was an only child and Harry was a big brother,” McIlroy said of his relationship with Diamond, per Golf Monthly. “We’re very close. I love having him on the bag. I’m a different person. And I’m never going to give him s— even if something goes wrong. It would not be worth it.” 

That patience when something goes wrong is undoubtedly the crux of why McIlroy went with Diamond. He split ways with Fitzgerald since during a slump he said he was too hard on his caddie. That doesn’t seem to be an option with Diamond.

Who is Harry Diamond?

Diamond keeps his personal life private; however, he was the best man at McIlroy’s wedding to Erica Stoll in 2017. McIlroy speaks extremely highly of Diamond as a caddie, having said he’s “one of the best” in the business. 

McIlroy has known Diamond since he was seven years old and Diamond was 12. They met at Hollywood Golf Club and stayed friends since, culminating in their business relationship.

Why did McIlroy stay with Diamond past 2017?

Despite being initially thought of as a short-term partnership, McIlroy seemed to be comfortable with Diamond. When he was slumping, McIlroy has said time and time again Diamond isn’t a person he can take his frustrations out on. That can be beneficial for someone as competitive as McIlroy.

What are McIlroy’s odds to win the PGA Championship? 

With a round in the books, McIlroy’s odds have been updated to +250, best in the field, per Fanduel. 

McIlroy is looking to capitalize on a strong first round, as he chases that elusive fifth major. He’s already won the PGA Championship twice, the last time coming at Valhalla Golf Club in Louisville, Kentucky. He’s lookin to repeat the feat with Diamond at his side for the first time.
