This week we’re discussing the most naturally anxiety-producing part of the team: the bullpen!
I asked y’all in the FEED to rank your top three Mariners relievers you are most worried about and the results did not make me feel less worried, that’s for sure. But, it’s good to air it all out. Let’s get into it and rate some TAKES.
First off, once again here’s my Trademarked Mariners Hot Take Ranking System: All right, let’s see what y’all’s top three picks are. Your third most worrisome Mariners reliever is…. Luis Castillo?!?!
Famously a starting pitcher, Castillo’s recent decline in performance has apparently has many fans ready to ship him to the bullpen. This is a scorching take, honestly Cliff Lee level, because if it happens, it means a lot of things have gone very wrong. What makes Castillo still effective even with diminished velocity is his command and his consistency.
I can see the argument that maybe he’ll be able to reach back for more velocity given the shorter appearances out of the bullpen, but with no real data to back that up, it’s entirely hearsay. Moving along, your second most worrisome Mariners reliever is…. Matt Brash An obviously popular answer, Brash hitting the IL with a bad oblique is a big blow to the Mariners cadre of high-leverage arms.
