PGA Championship: With Jim ‘Bones’ Mackay back in pursuit at Southern Hills, who are the most successful caddies in men’s majors of all time?

Caddie Jim ‘Bones’ Mackay is in pursuit of his sixth major title, but who has more?

Jim “Bones” Mackay is at it again, carrying the bag and helping to strategize for Justin Thomas in this week’s PGA Championship as Thomas has climbed the leaderboard. Bones has five major titles to his caddie credit, making him one of the most successful loopers of all time in golf’s biggest events.

But, he doesn’t have the most wins.

Below, find a list of some of the caddies who have looped for the most men’s major championships. The list includes some caddies you might have heard of, and plenty who worked in the era in which caddies received almost none of the credit and were often expected to “Show up, keep up and shut up.”

But most of them can claim plenty of credit in helping their golfers earn big titles. Then check out the Caddie Hall of Fame, from which some of this information has been obtained.
