Tiger Woods has been grouped with Spanish veteran Miguel Angel Jimenez and Korea's Sang-Moon Bae for the opening two rounds of the Masters.
The in-form Woods is the bookmakers' favourite for the tournament and will tee off on Thursday behind the traditional grouping of last year's winner South African Charl Schwartzel, US amateur champion Kelly Kraft and 2011 PGA championship winner Keegan Bradley.
World number one Luke Donald will launch his bid for a maiden green jacket one group behind Woods, with Italian Francesco Molinari and America's Nick Watney, while Northern Irishman Rory McIlroy will be joined by 2009 Masters champion Argentinean Angel Cabrera and American Bubba Watson.
In other groupings, world number three Lee Westwood, American Jim Furyk and Fiji's Vijay Singh are together, while Australian hope Adam Scott will set off with Bo Van Pelt of America and German Martin Kaymer.
Jason Day, who finished joint runner-up with Scott at last year's Masters, will tee off alongside American duo Kyle Stanley and Bill Haas.
Three-time Masters winner Phil Mickelson will tee off last at 1.53pm local time with Hunter Mahan, who enters the tournament as the highest-ranked American, and Sweden's Peter Hanson.
