Spieth, who is making his season debut this week in China, won in a 10-shot rout last year in Windermere, Fla. Day is currently at home in Ohio with his wife, Ellie, who is expected to give birth to the couple's second child this month. His appearance in the Bahamas will be his first competitive start since the Presidents Cup.
Spieth and Day will be joined in Albany by Zach Johnson, meaning all of the major winners from this year will be present.
The limited field will also include Rickie Fowler, Dustin Johnson, Matt Kuchar, J.B. Holmes, Chris Kirk, Patrick Reed, Jimmy Walker and Bill Haas, all of whom helped the U.S. to victory last month in Korea. Also participating are Adam Scott, Hideki Matsuyama and Anirban Lahiri, all of whom were a part of the International squad at the Presidents Cup.
Tournament host Tiger Woods will be unable to participate because of recent back surgery, but he is expected to make an appearance at the event, held Dec. 3-6.
