Tee times are out for the Masters. Here are five groups to keep an eye on during the first two rounds at Augusta National (all times EDT). Click here for full-field tee times:
Bubba Watson, Justin Rose, Gunn Yang (a): 9:24 a.m. Thursday, 12:42 p.m. Friday
Watson enters as the defending champ, eyeing a third green jacket in the last four years. He'll play with Yang in a traditional tee time grouping the previous year's winner with the reigning U.S. Amateur champ, while the three-ball will also include Rose, who has finished inside the top 25 at Augusta National each of the last four years.
Phil Mickelson, Rory McIlroy, Ryan Moore: 10:41 a.m. Thursday, 1:48 p.m. Friday
McIlroy headlines this group, as the world No. 1 goes for his third major in a row and the final leg of the career Grand Slam in an event where he squandered a late lead in 2011. Mickelson is looking for his fourth green jacket but enters without a top-10 finish to his credit for the second year in a row, while Moore won low amateur honors in 2005 and has missed the cut only once in six appearances.
Jordan Spieth, Henrik Stenson, Billy Horschel: 1:15 p.m. Thursday, 9:57 a.m. Friday
Spieth is one of the pre-tournament favorites, with three top-two finishes in his last three starts capped by a playoff loss last week in Houston. He finished T-2 in his Masters debut last year, nearly becoming the second player to win in his maiden appearance in the modern era. He'll play with each of the last two FedEx Cup champs, including Stenson who finished second at Bay Hill in his most recent start.
Tiger Woods, Jimmy Walker, Jamie Donaldson: 1:48 p.m. Thursday, 10:41 a.m. Friday
Woods makes his highly-anticipated return to action this week, his first competitive start since early February. He'll play the first two rounds with Walker, who has won five times since October 2013 and cruised to victory in San Antonio two weeks ago, and Donaldson, the Welshman who clinched the winning point at the Ryder Cup for the Europeans last year at Gleneagles.
Sergio Garcia, Jason Day, Rickie Fowler: 1:59 p.m. Thursday, 10:52 a.m. Friday
The opening round concludes with a strong trio of potential contenders, with all three ranked inside the top 15 in the world. The group is led by Day, No. 5 in the rankings who finished second at Augusta National in 2011 and followed with a third-place finish in 2013. Fowler finished T-5 here last year to spark a run of four straight top-five finishes in majors, while Garcia has three top-10 finishes at the Masters, most recently in 2013.
