Rory McIlroy will have former Irish Open winner Jon Rahm and Xander Schauffele for company for the first two rounds at The Masters.
The Ulster man landed the most recent of his four major titles in 2014 and will again be attempting to complete the career Grand Slam at Augusta this week.
McIlroy has been working alongside his new coach Pete Cowen in Georgia ahead of the first major of the season, after admitting to trying to make changes to his swing to compete with Bryson DeChambeau's long hitting from the tee.
Reigning Open champion Shane Lowry will play alongside fellow major winner Justin Rose and Matt Kuchar.
Offaly native Lowry will be playing Augusta for the sixth time in his career and he says the course is in "unbelievable shape" this week as he looks to build on his 25th-place finish at The Masters last season.
Defending champion and current world number one Dustin Johnson will be in a group with 2020 Race to Dubai winner Lee Westwood and last year's US Amateur champion Tyler Strafaci.
Brooks Koepka, who will teeing up for the first time since undergoing knee surgery, is in a three-ball with two-time Masters winner Bubba Watson and Viktor Hovland.
