Rory McIlroy's tee time for Thursday's first round of the PGA Championship at Valhalla has been set for 8:15 a.m. Eastern time at hole No 10. The Northern Irishman has been paired with Dustin Johnson and Justin Rose. 

Right before McIlroy tees off is the trio containing Tiger Woods at hole No 10 with an 8:04 a.m. start time. Woods is paired with Adam Scott and Keegan Bradley to start the four-day event in Kentucky.  

Scottie Scheffler has an afternoon start time, teeing off from hole No 1 at 2:13 p.m. alongside Wyndham Clark and Brian Harman. 

Defending champion Brooks Koepka will tee off two groups after McIlroy at 8:37 a.m. from hole No 10 with Jordan Spieth and Max Homa. 

Michael Block, who was last year's Cinderella story at the PGA Championship, is part of the first group to tee off at the tournament at 7:15 a.m. at hole No 1 as part of a trio with Shaun Micheel and Luke Donald. 

McIlroy will participate in his first tournament since filing for divorce from his wife, erica stoll on Monday. 

The 35-year-old McIlroy has not won a major tournament since 2014, which was the PGA Championship held at Valhalla in Louisville. 

Woods also won the 2000 PGA Championship that was held at Valhalla. This is the fourth time Valhalla has hosted a major tournament. The 2008 Ryder Cup was also held in Louisville. 

The trio of Jon Rahm, Rickie Fowler, and Cameron Young will tee off at 2:02 p.m. from hole No 1.  

Another star-studded trio of Justin Thomas, Ludvig Åberg and Xander Schauffele will tee off from 7:53 a.m. on the back nine. 

Phil Mickelson tees off at 1:51 p.m. on hole No. 1 alongside Collin Morikawa and Matthew Fitzpatrick. 

The last person to tee off at the PGA Championship will be either S.H. Kim, C.T. Pan, or Braden Shattuck, who tee off last at 2:57 p.m. at hole No 1.
