(BSS/AFP) - J.T. Poston survived late pressure from Doug Ghim, firing five birdies in a four-under par 67 to claim the third US PGA Tour title of his career on Sunday in Las Vegas, Nevada.

Poston, 31 and ranked 64th in the world, finished with a 22-under par total of 262 at TPC Summerlin, to beat Ghim by one stroke.

Ghim had an eagle and four birdies in his six-under par 65, including a six-foot birdie at the last that put him on 21-under 263.

Poston, tied for the lead when darkness halted play on Saturday, birdied three of his last five holes to complete a five-under par third-round 66 on Sunday morning to take a three-stroke lead over Ghim into the final round.

The tournament had been in catch-up mode since dangerous winds led to a four-hour delay on Friday.

Ghim had cut the deficit to one stroke with an 11-foot eagle at the par-five ninth.

But Poston rolled in a 21-foot birdie at the 12th and made a three-foot birdie at the par-five 13th to push his lead back to three.

Poston added a birdie at 15, but Ghim kept the pressure on with a birdie at the par-five 16th and Poston missed a four-foot par putt to bogey the par-three 17th and send them to the 18th tee with Poston`s lead down to two strokes.

That proved to be enough. After Ghim drained his birdie putt, Poston stepped up to make his four-footer for par to claim his first victory since the 2022 John Deere Classic.

"I just told myself this is what you dream of -- you`ve got a putt to win on the PGA Tour," Poston said, adding that he`d "just tried to forget" about poor putts on 16 and 17.

"Didn`t make very good strokes on either of them, but I just told myself I`ve made a million and (Ghim is) in this. Do one more."

Ghim, 28 and ranked 148th in the world, remains in search of his first PGA Tour title.

Germany`s Matti Schmid and Rico Hoey of the Philippines both carded five-under par 66 to share third place on 19-under 265.

American Michael Kim roared up the leaderboard with a final-round 62 for an 18-under par total of 266, sharing fifth with Davis Thompson and South Korea`s Lee Kyoung-hoon, who both shot 66.

South Korean Tom Kim, the 2022 and 2023 champion, missed the cut in his bid for a three-peat.
