Tampa Bay's initial manager search began with 10 candidates and has been whittled down to three: Wakamatsu, Kevin Cash and Raul Ibanez.
Wakamatsu, 51, is the Royals' bench coach and has Major League managing experience with the Mariners in 2009 and '10. Prior to that, he managed four seasons in the Minor Leagues and first coached in the Major Leagues with the Angels in 2001. Wakamatsu was the first Asian-American manager in the Major Leagues.
When they pared their list to three candidates, the Rays noted they would begin their final interviews on Dec. 1.
Cash and Ibanez will likely be in for their final interviews on Wednesday and Thursday, which could mean a decision might come as early as Friday.
The organization is hoping to have a manager in place by the Winter Meetings, which begin Monday in San Diego.
