Jason Giambi is returning to his professional baseball roots with the Oakland Athletics.
Giambi and the A's have finalized a one-year contract with an option, bringing the free-agent designated hitter and first baseman back to the place he began his big league career.
The sides had reached a preliminary agreement earlier this week but Giambi still needed to complete the obligatory physical Wednesday for the deal to get done.
Giambi, who turns 38 on Thursday, follows a line of aging and injury-prone designated hitters in recent years with the A's -- Frank Thomas, Mike Piazza, Mike Sweeney and then Thomas again. Giambi also could play some first base to give Daric Barton a break from time to time.
There is a 2 p.m. news conference at the colesium.
There are reports that it is actually a two-year deal for $4 million the first year and $6.5 milllion the second year.
Giambi turns 38 this week.
