Tiger Woods makes his return to the Memorial Tournament this week and he will tee off with the in-form Justin Rose at Muirfield Village.
A five-time champion at the event, hosted by Jack Nicklaus, Woods has not played the Memorial since 2015, when Rose finished runner-up to David Lingmerth.
And the Englishman heads into this year's edition in fine form, having claimed his ninth PGA Tour success at the Fort Worth Invitational on Sunday.
Alongside Rose and Woods will be defending champion Jason Dufner, who won by three strokes ahead of Rickie Fowler and Anirban Lahiri in 2017.
Eight of the world's top nine golfers are in action and four star-studded featured groups were confirmed on Monday, with Fowler joining Masters winner Patrick Reed and world number one Justin Thomas in another of those trios.
Jordan Spieth, Bubba Watson and Phil Mickelson form a group with 10 major victories between them while Rory McIlroy - runner-up to Francesco Molinari on the European Tour's BMW PGA Championship on Sunday - will play alongside Jason Day and Dustin Johnson.
