"I have been swinging some, and my injured wrist has not bothered me since last year," Ortiz told The Associated Press by e-mail on Thursday. "Just as I promised, if I'm healthy, I will join the team."
Ortiz played in the inaugural World Baseball Classic in 2006, hitting a prodigious home run off Johan Santana, who was pitching for Venezuela.
The left-handed masher suffered a partially torn tendon sheath in his left wrist on May 31 of last season and was on the disabled list until July 25.
Ortiz was candid in saying that he was never 100 percent for the rest of the season. However, after the Red Sox were knocked out of the American League Championship Series and Ortiz had a chance to rest, he said that his wrist felt noticeably better.
Ortiz hit .264 with 23 home runs and 89 RBIs in 109 games last year, all lows for him since he joined the Red Sox in 2003.
The Red Sox are expected to have several other players participate in the World Baseball Classic, including Daisuke Matsuzaka (Japan), Jason Bay (Canada), Kevin Youkilis (United States) and Dustin Pedroia (United States).
