Jim Furyk described his record-shattering 58 as "phenomenal" as he reflected on his historic final round at the Travelers Championship.
Furyk rolled in 10 birdies and one eagle in perfect scoring conditions at TPC River Highlands in Connecticut to record the lowest score in PGA Tour history, while he also became the first player to break 60 twice.
The last sub-60 round on Tour was posted by Furyk in the second round of the BMW Championship almost three years ago, but he went one better just a week after Stephan Jaeger fired the first 58 on the Web.com Tour.
"There's a lot of rounds by a lot of great players ahead of me that have never reached 58," said the 46-year-old afterwards. "To hold that record alone right now on the PGA Tour is phenomenal. To have a little small place in history is simply a dream.
"I'm still a little stunned and a little flabbergasted, it wouldn't have been a round that I would have expected coming. I played pretty well in Canada but really struggled through the week at the PGA Championship. I think I finished around 70th for the week, and I was in that position again starting this morning.
"I've really been struggling a little bit with my golf swing, I've played okay but not hitting the ball the way I expect and wanted to, and for the last couple of weeks I think put a little pressure on my game and tried to hit the ball probably a little farther and not knowing it or not doing it consciously.
"It took me a bunch of rounds of golf to kind of figure it out and to get back in the swing of things, and started to work on it on Friday, played a good round, but kind of lost that feel on Saturday. I was able to go to the range and I sent some video to my dad, texted back and forth with him, and kept working on some things in my set-up.
"It's kind of a reminder no matter how bad you feel with your swing you're never that far away, or no matter how good you feel you're probably not that far away from playing poorly, as well. I went out yesterday and really didn't have command of the golf ball, and turned around and played pretty much a flawless round of golf today.
Furyk holed out from 135 yards for eagle at the third and made seven consecutive birdies around the turn to stand at 11 under for the day after 12 holes before his momentum stalled with three pars, but he rolled in a 23-foot putt for his 10th birdie at the 16th and parred safely in.
"The putt at 16 was huge," Furyk added. "To see that go in and get it to 12 under par, and then it was, again, fighting emotions. A lot can go wrong at 17, so getting the ball in the fairway there was key. I hit one in the water early in the week.
"I didn't make a good swing off the tee, it was a little bit of a guided swing rather than letting it go, but I hit a good second shot, just gassed up a little bit and hit it too hard, and it was nice to grind out the little three-footer for par.
"And then at 18, I wanted to keep a little short right of the pin, and I think that shot from 17 was in my mind. I didn't want to go ahead and gas it again by the hole, and just came up a little bit short. But I hit a good first putt, and it's nice when the second ones are mindless and they're up there about a foot from the hole."
Furyk also explained how he drew on the "comforting" memories of shooting 59 in Illinois in 2013 to help keep his emotions in check and enabled him to close out his landmark round.
"I guess had I never shot 59 before, I probably would have been thinking 59 was the barrier," he said. "But the fact that I did it three years ago, in the back of my mind I've got to 11 under through 12 and I've got six holes to play. If I play them under par, I'm going to break another barrier.
"So having that experience in the past, and this one mimicked it a lot, it was comforting for me. You don't wake up on Sunday morning with an 8:41am tee time thinking that anything exciting is going to happen. The most exciting thing that can happen is the group in front plays quick and your flight takes off a little early and you get home early.
"To get out there and make a bunch of birdies and get the juices flowing and feel like I was in the hunt in a golf tournament was kind of cool."
