Andrew Ruthkoski, a pro golfer based in Muskegon, Michigan, has shot one of the most scarcely believable rounds of golf you're ever likely to hear about. Stepping out for a casual Sunday evening game with his twin stepdaughters, the 39-year-old broke his own course record at Oak Ridge Golf Club, setting a new benchmark of 17-under 55. No, that's not a typo.

Ruthkoski's previous best was an 11-under 61, which he had unbelievably matched by the time he stood on the tenth tee thanks to four(!) eagles, three birdies and a couple of pars in a front-nine 25. 

To that end, he came home in a modest 30 for the record score that you'd like to think will stand the test of time. However, he nearly called it quits after six holes, according to the report in The Detroit News (opens in new tab).

It was 8.45pm by the time Ruthkoski had opened his account with three eagles and three birdies, and that's the time by which the clubhouse asks for carts to be returned. With that in mind, Andrew's stepdaughters decided that was enough and returned their vehicles so club employees weren't waiting around.

Luckily, fate intervened, with Ruthkoski's friend Dave Buck, who has a house next to the course and his own cart, offering to drive the rest of the way, sensing the slice of history that was on the horizon.

Pars would follow at the seventh and eighth, stalling the momentum slightly, before Ruthkoski drove the par-4 ninth and converted the 20-footer for eagle. After a birdie at the tenth, the 39-year-old began to feel the pressure of posting a sub-60 round.

At 12-under through 12, he recovered from a poor tee shot on the 13th to birdie the par-5, which sparked a run that would see him storm to the finish. 

He nearly holed his tee shot on the par-3 14th. Birdie. He nearly holed from 30 feet for eagle on the next. Birdie. He hit the flagstick with his approach to the par-4 17th. Birdie. And he sensibly dribbled a slick eagle putt to tap-in range on the last. Birdie.

All in all, four eagles, nine birdies and five pars went into the making of Ruthkoski's 55 that wrapped up just shy of 10pm local time. Check out his scorecard below:

"It's like a scramble score," the man himself said. "With five guys, we can shoot 18-under. We play a scramble out here for the City of Muskegon, it supports Mona Shores High School, that's the big one that's out at that course. And guys are texting me, 'You're gonna be a one-man scramble team this year!'"

Ruthkoski is next in action at the pre-qualifier for next week's John Deere Classic. If form is anything to go by, he's a shoo-in.

A lifelong golf fan, Andy graduated in 2019 with a degree in Sports Journalism and got his first role in the industry as the Instruction Editor for National Club Golfer. From there, he went on to enjoy a spell freelancing for Stats Perform producing football reports, and then for RacingNews365 covering Formula 1. However, he couldn't turn down the opportunity to get back into the sport he grew up watching and playing and now covers a mixture of equipment, instruction and news for Golf Monthly's website and print title.


Andy took up the game at the age of seven and even harboured ambitions of a career in the professional ranks for a spell. That didn’t pan out, but he still enjoys his weekend golf at Royal Troon and holds a scratch handicap. As a side note, he's made five holes-in-one and could quite possibly be Retief Goosen’s biggest fan.


As well as the above, some of Andy's work has featured on websites such as goal.com, dailyrecord.co.uk, and theopen.com.
