And now the Presidents Cup captain will get a closer look at his American players for the rest of the year. 

The victory on Sunday (Monday AEST) should get him into high-profile tournaments, which the 45-year-old might not have been expecting to play in.

Karl Vilips was the leading Australian, finishing in a tie for 24th place at eight-under.

Ryan Ruffels tied for 45th at five-under, with Cam Davis finishing in a tie for 67 at one-under for the tournament.

Snedeker drove into the right trees on the 18th hole at Dunes Golf and Beach Club, pitched out to the fairway and two-putted from 30 feet for bogey.

"I feel amazing," said Snedeker, whose last win was the Wyndham Championship in 2018. 

"I feel so lucky to still be out here still doing what I love to do. To have a chance to win a golf tournament at my age and to be able to pull it out is something super special. I'm just so pumped."

Mark Hubbard, seeking his first PGA Tour win in his 274th start, was tied for the lead when he did the same thing - a drive into trouble on the right, with no real option but to pitch back to the fairway, and a 25-foot par to force a playoff that missed. Hubbard shot 70 to finish second at 17-under.

Snedeker finished at 18-under (266) for his 10th career PGA Tour victory. 

Because the Myrtle Beach Classic is held opposite the signature event at Quail Hollow, the victory does not give him a spot in the Masters, only the PGA Championship.

But it also comes with a two-year exemption - massive for Snedeker, having spent the past few years trying to recover from sternum surgery and not getting any younger.

"To not have my card the last couple of years, to be struggling to do what I love, to still have a passion to play this game the way I want to play it and to show people how I can still do it," Snedeker said. 

Beau Hossler (68) and Kevin Roy (69) tied for third, two shots behind.

Blades Brown, the 18-year-old who graduated high school in January, shot 67 and tied for ninth; his second top 10 on the PGA Tour this year.
