Herrmann, 30, completed a two-year run with the Diamondbacks in 2017. Despite racking up a career-best 10 home runs in the majors, the veteran catcher/outfielder finished the year with a disappointing .181/.273/.345 batting line and -0.7 fWAR in 256 plate appearances. His career averages are only slightly better: a .202/.278/.344 batting line, 22 home runs and 10 stolen base scattered across seven seasons. (It’s also worth noting that he’s never played more than 106 games in a single season before; prior to 2017, he had yet to make more than 60 appearances in any one major league gig.)
Still, the Mariners are in desperate need of additional catching depth with Mike Zunino still on the mend from an oblique injury. They jettisoned Triple-A backstop Tuffy Gosewisch on Thursday and are expected to utilize Herrmann as Tacoma’s primary catcher this spring. Per Curto, Herrmann has already been working out with the team and could be activated at any point.
