The Colorado first-baseman recently had hernia surgery to keep the possibility of a 2013 season alive.
Giambi, 41, will be the last in-house candidate to interview before the Rockies begin interviews with outside candidates. A five-time All-Star, Giambi has been with the Rockies since 2009 and underwent hernia surgery following the 2012 season to keep the option of a 2013 season alive.
Despite not having any coaching experience, Giambi has worked with Rockies players on hitting and frequently talked strategy with former manager Jim Tracy. With 429 career home runs, Giambi ranks No. 43 all-time in home runs and earned the 2000 AL MVP award during his time with the Oakland A's.
There is no timetable for the Rockies to sign a new manager as only one other team, the Boston Red Sox, have a managerial opening.
