The club announced the deal Friday.
The 41-year-old Ibanez hit .242 with 29 homers and 65 RBI for the Seattle Mariners last year. He hit his final homer of the season at Angel Stadium on Sept. 21, tying Ted Williams' record for the most homers by a player 40 or older.
Ibanez has 300 career homers and is seven hits shy of becoming the 18th active major leaguer with 2,000 hits. He played his first major-league game with Seattle in 1996, also making stops with the Royals, Phillies and Yankees between three stints with the Mariners.
