CROMWELL, Connecticut — Fifty eight.

It was a number that only existed in golf folklore until Sunday.

Then Jim Furyk made it a reality.

The 46-year-old Furyk turned an eagle, 10 birdies and seven pars into a PGA Tour-record 12-under-par 58 in Sunday’s final round of the Travelers Championship at TPC River Highlands.

“Just cool,” an admittedly stunned and flabbergasted Furyk said. “It’s kind of a reminder no matter how bad you feel with your swing you’re never that far away.”

The magic began when Furyk holed out for eagle on the 419-yard, par-4 No. 3 hole after a birdie the hole before. His opening-nine score of 8-under 27 set a Travelers record.

It was one shot off the PGA Tour’s nine-hole record of 26, set by Corey Pavin in the opening round of the 2006 U.S. Bank Championship in Milwaukee. The last nine-hole 27 on tour was carded by Ryan Palmer at the 2015 CareerBuilder Challenge.

On the back nine, Furyk opened with three consecutive birdies to complete his string of seven straight, the longest streak on the PGA Tour this season.

His birdie on No. 16 dropped him to the historic 58 number with pars on the last two holes.

In a fun twist, Furyk was the last of six players in PGA Tour history who had come closest to the number, carding a 59 in the third round of the 2013 BMW Championship at Conway Farms Golf Club in Lake Forest, Ill.

Two other professionals have recorded 58s: Germany’s Stephan Jaeger on the Web.com Tour in this year’s Ellie Mae Clasic and Japan’s Ryo Ishikawa on the Japan Golf Tour at the 2010 The Crowns.

Furyk, who finished at 11-under 269 for tournament, now has the distinction of being the only player ever to record two rounds in the 50s.

“Having that experience in the past, and this one mimicked it a lot, it was comforting for me,” said Furyk, who hit 13 of 14 fairways and all 18 greens with 24 total putts. “You don’t wake up on Sunday morning with an 8:41 tee time thinking that anything exciting is going to happen.”

Furyk might have won the battle, but Russell Knox won the war.

Furyk’s record was the buzz of the golf world, but it was Scotland’s Knox who hoisted the Travelers Championship trophy later in the evening.

Knox rolled in a 12-foot par putt to avoid a playoff with hometown hero Jerry Kelly, giving him a one-stroke victory at 14-under-par 266 at TPC River Highlands.

“I dominated (Jim),” Knox said jokingly. “I guarantee you he would trade places very quickly with me.”

Knox is just the third international player to win the Travelers title since 1996 (Sweden’s Fredrik Jacobson in 2011, Australia’s Marc Leishman in 2012).

The 31-year-old joined Jason Day, Dustin Johnson, Jordan Spieth and Adam Scott as the only two-time winners on the PGA Tour this season.

Knox, the world No. 26, had one previous victory on tour at the World Golf Championships-HSBC Champions in November 2015, becoming the first player from Scotland to win a WGC event.

Kelly, an alumnus of the nearby University of Hartford, took second after a final-round 64.

Justin Thomas and Patrick Rodgers (268) tied for third and Furyk (269) headlined a four-way tie for fifth with Robert Garrigus, South Africa’s Tyrone Van Aswegen and 54-hole leader Daniel Berger.
