Bubba Watson, Martin Kaymer and Rory McIlroy have been paired together for next week's PGA Championship.
The Masters, U.S. Open and Open Championship winners will tee off round one at 1:45 p.m. ET on Thursday on the first tee at Valhalla Golf Club. They will start round two on No. 10 at 8:35 a.m.

This year's major winners also have plenty of big names surrounding them as well.

After them will be Gary Woodland, Graham DeLaet and Gonzalo Fernandez-Castano.
U.S. Ryder Cup captain Tom Watson will play the opening two rounds with 1998 PGA runner-up Steve Stricker and two-time runner-up Sergio Garcia. Playing in front of this year's major winners will be Henrik Stenson, Ryan Moore and local favorite Kenny Perry.
McIlroy's group will be followed by three of the last five PGA Championship winners - Jason Dufner, Y.E. Yang and Keegan Bradley. Next up is Luke Donald playing with another local favorite J.B. Holmes and Francesco Molinari.
