Seattle announced the deal Wednesday following a physical. Gutierrez became a free agent after the Mariners declined his $7.5 million option, but he chose to return to Seattle for a sixth season hoping he can finally stay healthy.
Gutierrez won a Gold Glove in 2010 but has spent most of the past three seasons on the disabled list. He missed 106 games last season with hamstring problems that led to two extended stints on the DL.
If healthy, Gutierrez could solve one of Seattle's big concerns going into season about who will play in center field. The Mariners appear to have options at the corner outfield spots with the recent moves to acquire Logan Morrison and Corey Hart.
In addition to his base salary, Gutierrez can earn performance bonuses based on plate appearances.
