Lucas Glover clinched his fifth career PGA Tour title with a final round of two-under par 68 on Sunday to capture the season-closing Wyndham Championship.

The 43-year-old American won by two strokes over Russell Henley and South Korean An Byeong-hun at Greensboro, North Carolina, in the final event before the PGA playoffs.

The 2009 US Open champion took his first tournament since the John Deere Classic two years ago to ensure his place in the FedEx Cup playoffs, catapulted from 112th to 49th in the season points standings.

Glover has battled with the "yips" frequently through the past decade but said he had found the consistency he needs to win.

"It starts and ends there with me and you know it has been a long road, 10 years of fighting something and to find something that completely changed the momentum and everything was obviously a blessing," he said.

The top 70 players in the standings advance to the playoffs and that prospect added some extra spice to the final round at Sedgefield Country Club.

Two-time major winner Justin Thomas and Australian Adam Scott, the 2013 Masters champion, both missed out on playoff spots by a single stroke.

The FedEx Cup playoffs begin with the St. Jude Championship in Memphis, Tennessee next week before moving on to the BMW Championship in Illinois and conclude in three weeks at the Tour Championship in Atlanta.

Thomas finished one place outside the playoff spots in 71st but came agonizingly close to making it on the final hole.
