Rory McIlroy has been playing a reduced schedule this season, but caddie Harry Diamond has still earned a huge sum
Rory McIlroy has been operating on a lighter schedule this season, yet he has still accumulated a considerable sum in prize money — a healthy portion of which has been passed down to caddie Harry Diamond.
Diamond, McIlroy’s close friend and long-standing bagman, has earned more in 2026 alone than many players will pocket across an entire season. Estimates place his earnings for the year somewhere between $750,000 and $850,000 (£557,240 and £631,540).
These figures are calculated on the standard caddie pay structure. Typically, caddies receive a 10 per cent cut following a victory, five per cent for a top-10 finish, and five per cent whenever their player makes the cut.
Diamond’s biggest payday of the year came at the Masters, where McIlroy successfully defended his title at Augusta National, pocketing a record $4.5 million (£3.3m) winner’s cheque — leaving Diamond with a $450,000 (£334,000) share for his 10 per cent cut.
That single payout alone put Diamond ahead of a significant number of PGA Tour professionals for the year. McIlroy then added a further $840,000 (£631,000) from the PGA Championship, U.S. Open and The Open, including $637,050 (£473,300) from a T7 finish at the former as Aaron Rai claimed the title.
McIlroy’s 2026 campaign also included a T2 at the Genesis Invitational, a T12 at the Memorial, and a T7 at the Genesis Scottish Open, though he will not feature in the upcoming FedEx St. Jude Championship. Even his T46 finish at The Players, T32 at the U.S. Open, and T40 at The Open all contributed to the overall earnings.
A level-par performance at The Players brought in $72,000 (£53,000), while a T40 at The Open generated $69,000 (£51,000) – his most modest payday of the season.
McIlroy’s showing at Aronimink secured Diamond another substantial sum in bonus payments. McIlroy himself has amassed $8.5m (£6.3m) in official prize money this season and stands a chance of hitting the $10m mark once again, having achieved it in 2025.
Consequently, several tour professionals’ earnings for 2026 place them behind Diamond, never mind McIlroy. Haotong Li stands at $741,536, with Keita Nakajima on $740,571, Stefano Mazzoli at $720,000, and Rico Hoey at $718,607.
Diamond isn’t topping the caddy earnings chart, however. World No.1 Scottie Scheffler has banked $16.9m (£12.5m) in prize money this campaign, with bagman Ted Scott estimated to have pocketed close to $1.4m (£1m) as a consequence.
The Northern Irishman’s background beyond golf is understood to be in the hospitality sector. His family has connections to pubs, hotels and eateries around Bangor and Belfast, and maintained links with the Marine Hotel and Dukes Hotel.
Today, however, it’s Diamond’s partnership with McIlroy that has earned him the substantial income. Despite a lighter schedule, the Masters champion is not expected to face any PGA sanctions for falling below the minimum tournament requirement.
