Peter Malnati made it five first-time winners in a row on the PGA Tour when he triumphed at the Sanderson Farms Championship on Monday.
The 28-year-old claimed a one-shot victory over William McGirt and David Toms in the weather-delayed event at the Country Club of Jackson.
The players returned early on Monday to complete their third rounds, with Toms and Patton Kizzire sharing the 54-hole lead on 14 under.
With some players getting through as many as 30 holes there were frequent changes at the top of the leaderboard, but it was Malnati's round of 67 and a final score of 18 under that proved enough.
McGirt (68) and Toms (69) shared second, with Kizzire (70), Aaron Baddeley (68), Bryce Molder (69), Jhonattan Vegas (69), and 36-hole leader Roberto Castro (68) a further shot back.
Malnati follows in the footsteps of Emiliano Grillo, Smylie Kaufman, and Justin Thomas in winning their maiden PGA Tour title this season.
The tournament was the first European Tour event since the sporting shutdown caused by the coronavirus pandemic.
The 23-year-old had started the final round three strokes behind his fellow American.
Poulter is six shots back heading into the final round.
The Englishman produced an excellent sand save on the last to see him finish the day at 10 under par.
The 44-year-old’s last appearance on the PGA Tour was in mid-February.
The biennial match between the United States and Europe will now take place in September 2021 at Whistling Straits.
Organisers hope to stage the event in September 2021.
