The cosmic ideal of a modern-era swingman, Díaz has oscillated between Seattle’s long relief mix and Triple-A Tacoma for the majority of the last two seasons, making six appearances (one start) during that span at the highest level. The 28-year-old southpaw heads back to the minors until another emergency situation leads to his return.
