For the fourth time at the Open Championship, Tiger Woods and Justin Rose have been paired together in the first two rounds.
The duo, who will be joined by Spain's Sergio Garcia, were also partners at Muirfield in 2002, Carnoustie in 2007 and St Andrews two years ago.
They tee off at 9.42am in the first round on Thursday and then 2.43pm on Friday.
Just ahead of them each day will be defending champion Darren Clarke and Lee Westwood - but not together.
Clarke begins his bid to retain the Claret Jug at 9.09am in the company of 2002 winner Ernie Els and American Zach Johnson, winner of the John Deere Classic in Illinois this weekend.
Westwood, making his 58th attempt to lift a major title, is alongside Masters champion Bubba Watson and Japan's comparatively little-known Yoshinori Fujimoto.
Those arriving really early will have the chance to see three former winners playing together. Sandy Lyle and Americans Todd Hamilton and Mark Calcavecchia will be on the first tee at just after 7am - yet the championship will be well under way by then.
Because the field is 157, one more than usual because of all the different exempt players, the action kicks off at 6.19am with a two-ball of 52-year-old former Ryder Cup player Barry Lane, who came through qualifying, and American James Driscoll.
World number one Luke Donald has been paired with Phil Mickelson, but they have to wait until 2.43pm on Thursday to hit their first shots - and both Rory McIlroy and Padraig Harrington are afternoon starters as well.
Second-ranked McIlroy is with 2010 champion Louis Oosthuizen and reigning USPGA champion Keegan Bradley at 2.21pm, followed by 2007 and 2008 winner Harrington alongside young American Rickie Fowler and European amateur champion Manuel Trappel.
