For World No.1 Rahm, who finished runner-up to Justin Thomas for the PGA of America honours last year, it marked the first time in his career that he clinched the points-based award that factors in tournament wins, official money and scoring average.

Rahm, who finished one shot back of Patrick Cantlay in the season-ending Tour Championship on Sunday in Atlanta, tallied a career-best 75 Player of the Year points, five more than runner-up Bryson DeChambeau.

Rahm, who recorded a PGA Tour-leading 15 top-10 finishes in 22 events, also won the Vardon Trophy with an average score of 69.3. Dustin Johnson finished runner-up (69.619) while South African Louis Oosthuizen (69.714) was third.

Earlier on Tuesday, Rahm was named a finalist for the PGA Tour's Player of the Year award, which will be determined by a vote of his peers, along with Cantlay, DeChambeau, Collin Morikawa and Harris English.
