JT Poston won the Shriners Children's Open in Las Vegas to claim his third PGA Tour victory, meanwhile Julien Guerrier was victorious at the Andalucia Masters.
American Poston opened a three-shot lead when he finished off the wind-delayed third round on Sunday morning, holding off Doug Ghim to win by one shot.
Playing his first event since August, Poston moved ahead when he holed a birdie putt from 20 feet on the 14th hole as he resumed his third round.
It was a lead he never surrendered, three birdies on four holes on the back nine of the final round giving him a four-shot lead.
That cushion was reduced to one after Poston bogeyed the 17th and Ghim birdied the last to complete a round of 65.
But Poston held his nerve to hole from four feet on the last for a par to complete a final round 67.
Germany's Matti Schmid and Rico Hoey from the Philippines were a shot further back.
In Spain, France's Guerrier defeated Spain's Jorge Campillo in a record-equalling play-off to win his first DP World Tour title in the Andalucia Masters.
Guerrier made par on the ninth extra hole after Campillo was unable to get up and down from a greenside bunker, the pair having finished tied on 21 under par following closing rounds of 70 at Sotogrande.
Campillo had also bogeyed the 18th hole in regulation before Guerrier holed from 15 feet to force extra holes.
In a remarkable coincidence, the 39-year-old's coach Raphael Jacquelin won a nine-hole play-off for the Spanish Open in 2013.
The only other DP World Tour event decided by a nine-hole playoff was the 1989 Dutch Open, won by Jose Maria Olazabal.
An emotional Guerrier told Sky Sports: "I can't believe it. Jorge is a great player. I knew it would be really hard because his putting is amazing and also my iron game was not in good shape today.
"But my putting was really good so I was trying to do my best and I'm really, really happy.
"On the last putt I was thinking of my kids to give me the strength to hole it and I did so thanks to my family and my team. It's been a long wait and I'm really happy.
"French golf is very good right now and seeing the other guys win out here gave me so much belief that my time would come, and I could win.
"It still hasn't sunk in and I will go back home and spend some time with my family to celebrate."
Campillo, who holed from 15 feet for par on the first play-off hole, had chances to win on the third, seventh and eighth extra holes, but missed from six, 10 and 15 feet respectively.
England's Dan Brown finished two shots outside the play-off on 19 under par following a final round of 69.
Two-time major winner Jon Rahm carded a closing 67 to finish sixth on 17 under.
