Tiger Woods is one of five golfers who could leave Bethpage on Sunday ranked No. 1 in the world.

Dustin Johnson sits atop the Official World Golf Rankings entering this week's PGA Championship in Farmingdale, N.Y., followed in the top five by Justin Rose, defending PGA champion Brooks Koepka, Rory McIlroy and Justin Thomas.

Thomas withdrew this week due to a wrist injury.

Rose, Koepka and McIlroy could all ascend to No. 1 with a victory at the PGA.

It's a little more complicated for Woods, who climbed from 13th to sixth following last month's Masters triumph. Woods not only must capture his 16th major championship, he also needs Johnson to place outside the top 10 and for Rose and Koepka to finish worse than second.

That scenario would vault Woods to No. 1 for the first time since March 2013. Woods has spent a record 683 weeks in that position, including most of the 2000s.
