Tiger, Rory in back-to-back groups at PGA Championship

Pairings for the first and second rounds of the PGA Championship at Valhalla Golf Club in Louisville, Ky., include back-to-back groupings featuring Tiger Woods and Rory McIlroy, who are among past Wanamaker Trophy winners on this course.

Woods' group hits the first tee box, starting at No. 10, at 8:04 a.m. EDT Thursday and will tail a group that includes Justin Thomas. McIlroy, Dustin Johnson and Justin Rose will follow the Woods trio at 8:15 a.m.

Defending PGA Championship winner Brooks Koepka anchors a marquee grouping with Max Homa and Jordan Spieth. They'll open on the back nine at 8:37 a.m. EDT on Thursday.

Woods, who posted a playoff win over Bob May to win the 2000 PGA Championship at Valhalla, is joined for the first two rounds by playing partners Adam Scott and Keegan Bradley.

World No. 1 and Masters champion Scottie Scheffler starts at hole No. 1 on Thursday with a scheduled tee time of 2:13 p.m. in a pairing with Wyndham Clark and Brian Harman. The trio immediately follows Jon Rahm, Rickie Fowler and Cameron Young.
