Open champion Cameron Smith has won his first LIV golf trophy and a prize of four million dollars (£3.5 million) on his second start in the competition.
The Australian, who left the PGA Tour for the controversial Saudi Arabia-backed tournament after becoming world no at the Chicago Invitational.
The 29-year-old was briefly threatened in the third and final round at Rich Harvest Farms, but he restored his lead with a birdie on the 17th to ensure neither Dustin Johnson nor Peter Uihlein could catch him.
The Americans finished second after every birdie on the par-5 18th hole. Johnson finished at 70 while his compatriot Uihlein finished at 69 – both earning $1,812,500 (£1,589,417) from the $20m (£17.5m) purse.
Johnson is the only player from the 48-man field to finish in the top 10 at every LIV Golf event and remains one of the most important players to sign.
The 38-year-old is a two-time Major champion who has been number one in the world for longer than any player since Tiger Woods.
The next LIV Golf event will take place in Bangkok in three weeks.
The series will not return to America until the final team event at Trump Doral near Miami in October.
In addition to Smith and Johnson, the Saudi Arabia-backed rebel tour has attracted Brooks Koepka and Bryson DeChambeau.
