Rory McIlroy has been grouped alongside world No 1 Dustin Johnson and Justin Rose for the opening two rounds of the 121st US Open at Torrey Pines.
McIlroy, who claimed the first of four major titles in the 2011 contest, has been included in a marquee threeball alongside two other former US Open champions, with the trio going out in the afternoon wave at 1.36pm (9.36pm BST) on Thursday.
Defending champion Bryson DeChambeau, who stormed to a six-shot win at Winged Foot in September, is also among the afternoon starters as he competes with Masters winner Hideki Matsuyama and reigning US Amateur champion Tyler Strafaci.
Eight-time PGA Tour winner Brad Faxon reported that DeChambeau turned down the opportunity to tee it up alongside rival Brooks Koepka, who is instead grouped with former PGA Champions Justin Thomas - who can move to world No 1 this week - and Collin Morikawa.
Phil Mickelson, who became the oldest major winner in history at last month's PGA Championship, will begin his latest bid to complete golf's career Grand Slam among the morning starters at 7.51am (3.51pm BST) with Max Homa and Xander Schauffele.
The three most recent European winners of The Open have all been put together, with 2016 champion Henrik Stenson and 2018 Champion Golfer of the Year Francesco Molinari alongside reigning Claret Jug holder Shane Lowry, while Tyrrell Hatton, Matt Fitzpatrick and Viktor Hovland make up another all-European threeball.
Jon Rahm, the bookies' favourite to register a maiden major title this week, goes out with 2018 Masters champion Patrick Reed and Australian Marc Leishman - all former winners of the Farmers Insurance Open that's held at the same venue.
Last year's runner-up Matthew Wolff partners Tommy Fleetwood and Brian Harman, while former US Open champions Webb Simpson, Martin Kaymer and Gary Woodland will all compete in the same group over the first two days.
