After a one-week demotion, Jon Rahm is back to the top spot in the Official World Golf Rankings.
Rahm reached world No. 1 for the first time in his career last month with his victory at the Memorial, only to drop back to No. 2 when Justin Thomas captured the WGC-FedEx St. Jude Invitational. But Rahm's T-13 finish at the PGA Championship was enough to edge him back in front of Thomas, who tied for 37th. The margin remains thin: Rahm's new point average is 8.78, while Thomas' is 8.77.
New PGA champion Collin Morikawa jumped seven spots from No.
