Here's How Much Winning Caddie Harry Diamond Made After Rory McIlroy's Victory At The 2025 Masters

On Sunday, Rory McIlroy won The Masters to fulfil so many of his childhood aspirations - from winning at Augusta National to completing the career Grand Slam.

After holing out for birdie in a playoff against Justin Rose, McIlroy slumped down to the putting surface and allowed the magnitude of his achievement to wash over him.

Greeted instantly by caddie, Harry Diamond, the pair walked off the 18th green knowing they had etched their names into the history books and banked a whole heap of cash, too.

Among the many perks of winning The Masters is the sizeable winner's check that players receive. For 2025, The Masters had a record $21 million tournament purse up for grabs and, on Sunday night, McIlroy scooped a $4.2 million prize.

But it's not just McIlroy who will benefit from another significant bump in earnings, Diamond is likely to receive a share of the prize money given his contribution to the victory.

When it comes to payment, a player will usually give his caddie 10% of a winning check, around 7-8% of a top-10 prize and possibly 5% or so if they make the cut bit end slightly lower down the leaderboard. They will also be on an annual or weekly salary anyway, with cut money seen as a bonus.

As a result of McIlroy's $4.2 million paycheck from Augusta National, Diamond could conceivably collect a $420,000 bonus (before tax).

Last year, World No.1 Scottie Scheffler won a second Green Jacket and, in the process, claimed the $3.6 million first prize. That allowed his caddie, Ted Scott to potentially earn an additional $360,000.

The Masters was just one of many trophies claimed by Scheffler in 2024. Reportedly, Scott's earnings stood around $5.3m that year, which was more than the average PGA Tour player and even more than the likes of Justin Thomas, Russell Henley, and Brian Harman.

McIlroy's looper is in a similar position already, with Diamond's earnings for 2025 exceeding the PGA Tour average and surpassing the $1 million mark midway through April.
