Rory McIlroy's caddie Harry Diamond has earned more than some of the Northern Irishman's PGA Tour rivals this season, despite McIlroy reducing his commitments after winning a second Green Jacket.
Most PGA Tour caddies work through a complete season to earn their income, but Diamond has already banked an estimated £558,000 ($750,000) to £632,000 ($850,000) in 2026 simply by working for McIlroy. The figures represent the standard caddie compensation, with bonuses typically set at 10 per cent for victories, seven per cent for top-10 placements, and five per cent for made cuts.
Masters windfall
Diamond has carried McIlroy's bag since 2017 and could be earning considerably more through other bonuses. The largest windfall arrived at Augusta National following McIlroy's second successive Masters triumph and collection of a record £3.3m ($4.5m) winner's cheque. The title secured Diamond an estimated 10 per cent share worth an enormous £334k ($450k).
That bonus alone positioned Diamond ahead of numerous PGA Tour players for the year. He accumulated another £625k ($840k) from the PGA Championship, US Open, and The Open, including £474k ($637,050) for a T7 placement at Aronimink. McIlroy's result at Aronimink probably delivered Diamond another £37k ($50k) to £44k ($60k) in bonus payments.
Comparing earnings
McIlroy himself has accumulated £6.3m ($8.5m) in official prize money this season, and numerous Tour players have secured less than he and Diamond. Haotong Li sits at £551k ($741,536), Keita Nakajima at £551k ($740,571), Stefano Mazzoli at £535k ($720k) and Rico Hoey at £534k ($718,607). The list continues with Rasmus Hojgaard, Matthieu Pavon, Beau Hossler, Matt Kuchar, Luke Clanton, and Will Zalatoris all beneath the £558k ($750k) threshold.
FedEx Cup leader Scottie Scheffler has accumulated £12.5m ($16,911,275) in prize money this season. Calculations suggest that his caddie Ted Scott has pocketed nearly £1m ($1.4m) this season.
Season highlights
McIlroy's 2026 season featured a T2 finish at the Genesis Invitational, a Masters win, a T7 at the PGA Championship, a T12 at the Memorial, and a T7 at the Genesis Scottish Open. Even McIlroy's T46 at The Players, T32 at the U.S. Open, and T40 at The Open contributed to the figures. His even-par finish at The Players secured £61k ($72k) while a T40 at The Open delivered £59k ($69k) for his smallest earnings of the year.
Sources suggest that Diamond's wealth-building backstory originates in the Northern Ireland hospitality industry. His family has links to pubs, hotels, and restaurants throughout Bangor and Belfast, and maintains associations with the Marine Hotel and Dukes Hotel.
Currently, Diamond's most lucrative position is partnering with McIlroy, traversing 11 PGA courses over 157 days. Despite a restricted schedule, McIlroy is not expected to encounter any PGA penalties for falling short of the minimum event requirement.
