After Adam Hadwin became the second player in as many events to card a 59 on the PGA Tour, we look back at the others to have shot sub-60.
The first sub-60 round on the PGA Tour since it was established in 1929, Geiberger birdied his final hole in the second round to cement his place in golfing folklore at the Colonial Country Club in Tennessee.
After starting on the 10th, he made six birdies on the back nine before adding an eagle at the first hole, and he picked up four more shots before rolling in his historic eight-foot putt for a 59 on the ninth green. Geiberger would go on to claim the 10th of his 11 career victories.
Fourteen years after Geiberger's groundbreaking 59, Beck recorded the second in the third round at the Sunrise Golf Club.
Like Geiberger, Beck also started his round at the 10th and carded 13 birdies overall, including each of the last three holes after he confidently rattled in a three-foot putt on the ninth. But unlike Geiberger, Beck would eventually finish in a tie for third.
Duval enjoyed an incredible year in 1999, taking over from Tiger Woods as world No 1 while also firing a remarkable 59 on the final day to win his ninth PGA Tour title at PGA West.
Needing an eagle on the par-five final hole to break 60, Duval followed a perfect drive with a stunning second to six feet and he calmly rolled in the putt to snatch a one-shot win over Steve Pate - the first of four victories for Duval in the year.
Goydos became the first player to break 60 on a par-71 layout as he made a flawless start at TPC Deere Run with a 12-birdie opening round.
He held his nerve to hole from seven feet at the last, but he enjoyed only a one-shot lead as John Deere specialist Steve Stricker fired a 60 and went on to win the second of his three straight titles with a tournament-record score of 26 under par.
Just three weeks after Goydos became the fourth player to break 60, Appleby became the fifth as the Australian emulated Duval and carded a final-round 59 to clinch a one-shot win over Jeff Overton.
The only non-American to achieve the feat, Appleby's card featured one eagle and nine birdies on the par-70 layout, including his 11-foot putt on the final green which earned him his ninth PGA Tour title.
Furyk would break 60 during the second round and fail to win the tournament at Conway Farms, where he started at the 10th and covered the back-nine in just 28 strokes - including a hole-out from the fairway for eagle at the 15th.
The Ryder Cup regular made three straight birdies from the second before slipping back with a bogey at the fifth, but he got the shot back at seven and a nerveless four-foot putt on his final hole earned him a 59.
Four days after winning the Tournament of Champions, Thomas became the seventh player to shoot a round of 59 on his way to a convincing seven-shot victory.
Thomas chipped in for eagle at the 10th but bogeyed the next, before racking up eight birdies over his next 10 holes. He then capped off his round with an eagle-three on his final hole, sliding in from 15 feet.
Furyk blazed his way into the record books once again as he fired the first 58 in PGA Tour history during the final round at TPC River Highlands.
The American's astonishing round featured a hole-out from the fairway for eagle at the third as well as 10 birdies, including seven in a row around the turn. Furyk did have a look at a 57 on the final green, but two-putted for par.
