2011 winner Rory McIlroy has been paired alongside World No.1 Dustin Johnson at this week's US Open at Torrey Pines.

McIlroy will tee off at 13.36 (21.36 Irish time) alongside fellow former champions Johnson, 2016 winner at Oakmont, and Justin Rose, who triumphed in 2013 at Merion.

It's an early tee off on Thursday for the other Irish contender Shane Lowry, the reigning Open Champion who is coming off a very strong performance in the PGA Championship at Kiawah Island.

Lowry tees off at 07.29 (15.29 Irish time) with Francesco Molinari and Henrik Stenson.

But Brooks Koepka and Bryson DeChambeau will be on opposite sides of the draw as their simmering rivalry continues.

A number of spectators were escorted from Muirfield Village during the recent Memorial Tournament for shouting "Brooksy" at current US Open champion DeChambeau.

Four-time major winner Koepka, who was not competing, reacted to the news by posting a video on social media offering to reimburse any spectator whose day was "cut short" with a free case of beer.

The latest episode in the ongoing saga came a fortnight after leaked footage showed Koepka being unable to contain his dislike of DeChambeau after being distracted by his Ryder Cup team-mate during an unaired interview at the US PGA Championship.

Former player Brad Faxon told Sirius XM radio that DeChambeau and his agent had been asked if he would be happy to play with Koepka at Torrey Pines, but had declined.


Instead, DeChambeau will play alongside Masters champion Hideki Matsuyama and US Amateur champion Tyler Strafaci in the first two rounds, starting at 13.14 (21.14 Irish time) local time on Thursday.

Koepka gets his bid for a third US Open title under way at 07.29 local time (15.29 Irish time) alongside Collin Morikawa and Justin Thomas.

Six-times runner-up Phil Mickelson, fresh off a historic win at the PGA Championship and looking to complete the career Grand Slam on his home course, will start at 10.51 (18.51 Irish time) from the par-four 10th hole with Xander Schauffele and Max Homa.

Tournament favourite Jon Rahm will start on the back nine with former Masters champion Patrick Reed and Australian Marc Leishman.

For world number three Rahm, this will mark his first start since he was forced to withdraw from the Memorial Tournament with a commanding six-shot lead after 54 holes because of a positive COVID-19 test.

Rahm, in search of his first career major, will be in comfortable surroundings on the South Course at Torrey Pines as he has four top-10 finishes in five events played there.
