Simpson strung together three straight birdies on his back nine but needed an eagle on the par-four 18th hole in order to draw level with Poston. Byeong Hun An, on the other hand, had a more manageable challenge to force a possible playoff since a birdie on No. 18 would have put him at 22 under.

Since he teed off 20 minutes before An, Poston was like many fans across the country and watching the television broadcast as An wrapped up his tournament.

The drama faded quickly as An hooked his tee shot to the left of the fairway and required a drop. His second-shot approach put him on the green but left him with a 70-foot birdie putt. His putt sped inches away from the flagstick and over the cup, sealing his fate.

Sunday's brilliant final round was the culmination of an excellent tournament for Poston:

The 26-year-old was firing on all cylinders Sunday. He reached 14 greens in regulation and missed only four of the 14 fairways, per PGATour.com. He averaged 1.500 putts and gained 2.494 strokes on the green, both of which were his best single-round scores of the event.

Poston couldn't have picked a better location for his first-ever win on the Tour. He was born a few hours away from Greensboro in Hickory, North Carolina, and attended Western Carolina.

He said in his post-tournament interview some of his family and friends were on hand to witness his triumph.

Although Simpson made a late charge, he was left playing catch-up with Poston positioning himself atop the leaderboard. He left himself with too much work in too little time after going one under on the front nine.

Poston's performance left An with little room for error. A bogey on No. 15 and his errant drive on 18 was enough to tip the scales in Poston's favor.

Elsewhere in the tournament, Paul Casey tied for 13th at 15 under. Patrick Reed, Charles Howell III and Mackenzie Hughes earned a share of 22nd at 13 under. Sungjae Im, who turned heads with his opening-round 62, tied for sixth (16 under).
