SCOTTSDALE, Ariz. – They're the top two players in the field according to the Official World Golf Rankings, and they're also topping the list according to Las Vegas.

Jon Rahm and Justin Thomas are the two highest-ranked players at this week's Waste Management Phoenix Open, coming in at Nos. 3 and 4, respectively. Rahm played at nearby Arizona State and enters off a runner-up finish Sunday at Torrey Pines, while Thomas won earlier this month at Kapalua and is in search of his fourth victory in his last eight official starts.
