One of six players to shoot a 59 in PGA Tour competition, Furyk one-upped himself Sunday in the final round of the Travelers Championship, posting the first 58 in tour history.
"There's a lot of rounds by a lot of great players ahead of me that have never reached 58, so to hold that record alone right now, on the PGA Tour at least ... is phenomenal," Furyk said. "To have a little, small place in history is something you dream of."
Furyk started hot, playing his first four holes of the day in 4-under. He closed the front nine with four consecutive birdies to shoot a course-record 27 then opened the back nine with three more birdies.
From there, it seemed like his inevitable sub-59 score might not be so inevitable after all. He made par on the par-5 13th hole then followed with two more on Nos. 14 and 15.
Furyk needed to make one more birdie for the magic mark, and it came in the form of a 23-footer on the par-3 16th hole.
He closed with a pair of pars, hitting all 18 greens in regulation, to set the single-round record on the par-70 TPC River Highlands course.
"I'm hitting it well, I'm putting it well. It's trying to find a way to stay out of your own way really," Furyk said. "And don't let any thoughts leak in."
Furyk's first score in the 50s came in the second round of the 2013 BMW Championship. He is now the only player with multiple sub-60 rounds in PGA Tour history.
He had been 1-over entering Sunday and finished the Travelers Championship at 11-under 269.He is currently fifth on the leaderboard; the players ahead of him haven't teed off yet. Daniel Berger led the field at 15 under entering the final round.
Furyk's best finish in Cromwell was a fourth-place showing in 2000.
