GREENSBORO, N.C. -- J.T. Poston won for the first time on the PGA Tour with a bogey-free tournament, capturing the home-state Wyndham Championship on Sunday, Aug. 4, at Sedgefield Country Club in Greensboro.

Poston's final-round 8-under 62 on Sunday gave him a one-shot victory, finishing at 22-under 258 for the tournament.

Past tournament champion Webb Simpson shot 65 for second place for the second year in a row.

Third-round leader Byeong Hun An closed with a 67 and ended up in third place a 20 under. He went to the par-4 18th hole with a chance to force a playoff but made a bogey.

It marked the final event of the PGA Tour's regular season, moved up a few weeks from the past.

The last time a player won a PGA Tour event without a bogey was Lee Trevino in 1974 in New Orleans.

An's first bogey of the week came on the par-5 15th when he took a penalty stroke after his wayward tee shot. The South Korean responded with a birdie on the next hole.

Poston, 26, won two individual state championships for Hickory High School, about a 90-minute drive away. He played collegiately for Western Carolina.

Poston began the final round tied for fifth place, and pulled into a share of the lead by the eighth hole.

Simpson, also competing in his home state, bogeyed two of the first three holes. He putted in from off the green for a birdie on No. 7, and later recorded birdies on four of the last five holes.

Viktor Hovland, a rookie out of Oklahoma State, shot 65, putting him alone in fourth place at 19 under.

"I feel like I got a lot better over the last month and a half," Hovland said.

Si Woo Kim of South Korea shot 64 to finish 17 under and in fifth place.

England's Paul Casey, the highest-ranked golfer in the field at No. 8, was within two shots going to the back nine. His next shot landed in a fairway bunker and it took a couple of attempts to get out, carding a double bogey on the hole. His 69 dropped him to a tie for 13th at 15 under.

Patrick Reed, the 2013 champion here, shot 63 on Sunday for his best round of the week. That vaulted him to 13 under and a tie for 22nd.

Patton Kizzire (67) and Andrew Landry (68) finished tied for 13th and 19th, respectively, both moving inside the top 125 to advance to the FedEx Cup playoffs.

"It's a big relief off my shoulders," Landry said.
