When Jesse Martin started his round at Glenmary Country Club on Friday, he only set out to play nine holes in the afternoon.
He only agreed to play on because "I didn't have anything else to do," he told Fox Sports.
It's a good thing he did, as he shot a 16-under-par 56 on his second round of the day.
Whilst completing the remarkable achievement, Massie could not believe what he had achieved as he said: "I was at a loss for words at the end of the game when he added it all up. It was incredible."
"I was shaking" he added.
Glenmary club pro Jack Ridge also was taken aback at the news when Massie and his playing partners Kevin Purcell and Chris Miller returned to the shop on completion of their round.
"When he came in the pro shop, he was real fidgety and nervous-acting, and he said he needed an extra scorecard," Ridge recalls.
"I asked him what was going on, thinking, maybe he had a hole in one or something, and he said, 'Well, you won't believe this, but I just shot a 56.' And the two guys he was playing with shook their heads and said, 'Yes this really happened. This is for real, no joke. We played honest, USPGA rules, played the ball down and he shot 56."
Massie's round also included a one stroke penalty after his ball became stuck in a cedar tree two feet off the ground, but despite this he managed the incredible feat with 14 birdies, one eagle and three pars.
The NGA tour player admitted that the nerves that had built disappeared towards the end of the round. "I was more nervous when I got to 11- and 12-under par, because as a golfer, you really want break that 60 barrier," Massie said.
"When I got to 14-under I wasn't really nervous anymore. I was trying to get back to the clubhouse and just post the number."
And club pro Ridge also added more stature to the unbelievable round as he said: "It's got to be one of the greatest rounds of golf ever,".
