Tyler Duncan has sunk a 12-foot putt on the second hole of a playoff with Webb Simpson to claim his maiden win on the PGA Tour.
Playing two groups ahead of Simpson in windy conditions on Sea Island's Seaside Course, Duncan birdied three of his last four holes in regulation for a five-under 65.
He two-putted the par-5 15th for a birdie, made a six-footer on the par-3 17th and a 25-footer on the par-4 18th.
"I'm just so happy to be here playing and to come out here and win is just unbelievable," Duncan said.
The 30-year-old earned his first spots in the Masters and Tournament of Champions in Hawaii.
"Just so many different things that I'm very, very excited for," Duncan said.
Simpson birdied 15 and 16 and closed with two pars, making a five-footer on 18 to match Duncan at 19-under 263.
"It played really tough all day," Simpson said.
"It was blowing it seemed like a solid 20 and gusts here and there, and the pins were tough.
"They did a good job of setup, but they didn't make it easy for us."

Brendon Todd, seeking his third straight PGA Tour victory, took a two-stroke lead into Sunday but ran out of gas to finish fourth at 16 under after a 72.
"I was definitely tired on the back nine," Todd said.
Australia's Rhein Gibson, who was in contention at the midway point of the tournament, faded to finish in a tie for 43rd at seven-under while Matt Jones languished in a share of 72nd at one-under.
Duncan and Simpson played the 18th twice in the playoff, matching pars on the first extra hole.
"I was definitely nervous, yeah," Duncan said.
"I've been working really hard on controlling my emotions and breathing and all that stuff and it paid off down the stretch here, especially this playoff."
Simpson has four top-seven finishes in eight starts in the event.
The 30-year-old Duncan regained his PGA Tour card with a 12th-place finish in the secondary Tour's finals, after finishing 163rd on the main Tour standings in 2019.
