Tiger Woods already has three victories this season, but whether the 14-time major champion is truly back will likely be judged by his showing at Augusta.

The 2013 Masters begins at 8 a.m. Eastern time on Thursday morning, and Woods takes to the links at 10:45 am.

Perched at No. 1 since his win at the Arnold Palmer Invitational, the 37-year-old is also first on the money list with $3.7 million earned after five events this year, nearly a million more than fellow American Brandt Snedeker.

There are 14 groups set to tee-off before Woods's opening drive. The 2005 Masters champion is paired with Britain’s Luke Donald and American Scott Piercy.

Northern Ireland’s Rory McIlory, who took nearly three weeks off in preparation for the tournament, starts at 1:41 p.m. with American Keegan Bradley and Sweden's Fredrik Jacobson.

No. 2 McIlroy lost the world’s top ranking, but may have regained his form at the Valero Texas Open last week when he overcame four bogeys in the first round to finish 12-under for second place.

Both McIlory and Woods have downplayed any talk of a rivalry, and the 23-year-old might be coming into the Masters with a looser attitude. McIlroy chose his tennis star girlfriend Caroline Wozniacki to caddie for him during the Par 3 Contest Wednesday.

Phil Mickelson will be joined by Germany’s Martin Kaymer and South Africa’s Louis Oosthuizen at 1:30 p.m. Mickelson has three green jackets in his closet, the most recent coming in 2010. Since then Mickelson’s best finish at a major was his 2011 tie for second at the British Open.
