Sam Burns drained a putt from off the green to win the Charles Schwab Challenge in a playoff against world number one Scottie Scheffler.

Despite making no birdies on Sunday, Scheffler was in contention all day after entering the day in the outright lead, but had to battle with the difficult conditions later in the day to post a 72.

Burns was in much better touch, and had the benefit of getting his 18 holes out of the way earlier before the wind picked up, notching a 65 for the round of the day.

He was one shot back from a four-way tie at 10 under when he finished his tournament at nine under, and he had to wait two hours to find out – first if the field would come back to him – and then if Scheffler could hold on for the playoff.

Scheffler needed to save a number of tough pars down the back nine, including out of the bunker on the 18th hole to force the playoff, which he did by sinking a clutch five-footer.

In the playoff, after a pair of solid drives, Scheffler found the green a long way from the hole, while Burns put his approach just off the back of the putting surface. Approaching three hours since his last putt, Burns drained an incredible tournament-winner, with Scheffler not able to match him from distance.

Speaking to the media after securing the win, Burns said it was a hard-fought result.

"I think, just with the conditions today, and how tough it was playing, I'm just so proud of the way we hung in there," he said.

"I just played such a good round of golf today, and [caddie] Travis [Perkins] did a good job of keeping us in it, especially after hitting a foul ball at 12 which killed our momentum. Hitting that putt – that's just icing on the cake."

It is 11 years since Burns attended Colonial Country Club in person to witness David Toms win the Crowne Plaza Invitational, and he said it is hard to believe he is a champion at the same course.

"I don't know if I would've believed you – I remember that week like it was yesterday," he said.

"To finish it off here, and have [Toms'] family here… to add my name on that list now is really cool."

Scheffler's playing partner Brendon Todd finished one stroke outside the playoff, alone in third at eight under, while American trio Tony Finau, Davis Riley and Scott Stallings collected top-five finishes, tied for fourth at seven under. Finau and Burns were the only two players to shoot 67 or better in the final two rounds as the conditions worsened throughout the weekend.

A strong group rounded out the top-10, with pre-tournament favourite Jordan Spieth and US PGA Championship main character Mito Pereira headlining the five-man bunching in a tie for seventh at five under,

Spieth, Riley and Im Sung-jae – who was part of the logjam at three under – were the only three players to shoot 70 or better in all four rounds.

Norway's Victor Hovland was one of two players to finish at two under, while New Zealand's Danny Lee tied Burns for the round of the day, with his Sunday 65 bringing him to one under for the tournament.

Harold Varner III was part of the four-way tie for the lead at 10 under through 11 holes, but went triple-bogey, double-bogey, triple-bogey over his next three holes to plunge down the leaderboard and finish at even par.

Talor Gooch and Webb Simpson joined him at even par, Tommy Fleetwood finished at one over, and Collin Morikawa never shot worse than 71, but never shot better than 70 to finish two over.
