SEATTLE (AP) -- Ryan Garko and the Mariners have agreed to a $550,000, one-year contract, as Seattle tries to address its need for a right-handed hitter.

Terms of the contract obtained Monday by The Associated Press show the 29-year-old first baseman and designated hitter could nearly double his salary, to $1,075,000, if he becomes a regular for Seattle with 600 plate appearances.

Garko would earn up to an additional $25,000 each for 325, 350 and 375 plate appearances this season. The former Cleveland Indians and San Francisco Giants player would get $50,000 apiece for 425, 450 and 475 plate appearances, and $100,000 each for 500, 550 and 600 plate appearances.
