Garrick Higgo overturned a huge deficit to break through for his first PGA Tour title courtesy of a one-shot victory at the Palmetto Championship at Congaree.
Higgo entered the final round trailing by six strokes but the unheralded South African produced a three-under-par 68 to claim his maiden trophy in his second career start on Sunday.
The 22-year-old, who holed an eagle, three birdies and two bogeys, registered the largest comeback on Tour since Bubba Watson in 2018 as he upstaged world number one Dustin Johnson and the chasing pack.
Higgo became the first player to win in one of his first two career PGA Tour starts since Jim Benepe won the 1988 BMW Championship on debut, while he is the youngest winner on Tour this season – aged 22 years, one month and one day.
"It's amazing," Higgo said after finishing 11 under through 72 holes. "I just stayed patient all week. I'm just happy I didn't have to play in a playoff."
Hudson Swafford (66), Doc Redman (67), Jhonattan Vegas (67), Tyrrell Hatton (68), Bo Van Pelt (68) and overnight leader Chesson Hadley (75) ended the inaugural tournament tied for second position.
Ryan Armour (64) and David Lipsky (67) were a stroke further back, while American star Johnson had to settle for a share of 10th place at eight under following his final-round 70 in Gillisonville, South Carolina.
South Carolina native Johnson – who got within one stroke of the lead on the back nine – shot a seven at the par-four 16th hole for his first triple-bogey or worse on the PGA Tour since the 2020 WGC-FedEx St Jude Invitational and the 50th of his career.
