Jon Rahm fired a 7-under 65 on Sunday to win the Hero World Challenge by four shots.
The Spaniard entered the final round in a three-way tie for the lead with Tony Finau and Henrik Stenson but separated himself with a bogey-free performance at Albany Golf Course and finished at 20-under.
His win in the Bahamas is the 24-year-old's third worldwide victory in 2018.
Rahm, along with Patrick Cantlay, announced he would donate $500 to the California Strong Fund for every birdie made this week, which helps victims of recent California wildfires. Rahm carded 25 birdies while Cantlay posted 23, totaling $24,000 for charity.
Finau finished alone in second after a disappointing double-bogey on No. 14 knocked him out of serious contention.
Tiger Woods, who hosts the tournament in the Bahamas to raise money for his foundation, finished 17th in the 18-man field.
