Former Mariner Brad Miller is still on the market and along with Brock Holt, they are the only left-handed utility players worthy of an inquiry from Jerry Dipoto left on the free-agent market. However, I like Miller more than Holt making him the perfect fit for what Dipoto is looking for.
After a fairly underwhelming 3 years in Seattle to start his career, Miller was traded to the Rays. After hitting only 29 home runs in Seattle, Miller went on to have an amazing first season in Tampa Bay in 2016 hitting 30 home runs and he had a .786 OPS.
In his last two seasons, he has been fantastic in a utility role with Cleveland, Philadelphia, and St Louis, with an .853 OPS on 341 plate appearances in that time. He also has over ten games played at second base, third base, and left field in the past two seasons.
While Miller’s defensive stats are nothing special, especially at shortstop, he gives Dipoto and the Mariners the defensive versatility that they are looking for to play their two positions of need, second base and leftfield. He also should be relatively cheap, as Fangraphs predicts him to sign for 1 year and $2-5 million, which even with his low budget John Stanton will let Dipoto spend that.
