Mariners address bullpen by adding 2017 World Champion Astros reliever

Mariners' fans all over have been talking about the team's bullpen, and how they needed to make a move in order to give it a bit more experience and depth in advance of the trade deadline. The question became, what would the Mariners do? How would they address the pen? Would it be a signing? A trade? Prior to kicking off the series against the Orioles, we have an answer.

The Mariners have added journeyman reliever, and former rival, Chris Devenski to their bullpen. Technically he isn't there yet, as he will be reporting to Tacoma. However, he was signed to a Major League deal, and I'm guessing they are treating Tacoma as some sort of rehab/tryout mix. Giving him a few games there to see how he does before calling him up. He will actually be joined by Gregory Santos, who should be rehabbing there before seeing his first appearance in a Mariners uniform.

The Mariners have signed ex-Astros reliever Chris Devenski

While it is a move to address the bullpen, it can't be the only thing that the Mariners do. Devenski has had some incredible seasons and moments in his career, but as of late, it hasn't been that impressive. He was shelled to start 2024 in Tampa with a 6.75 ERA through 26.2 innings. 2023 was an up-and-down year that ended up with a 4.46 ERA and 3.96 FIP across 42.1 innings.

He's a changeup first pitcher (48%), followed by the 4-seamer (31%). Trailing behind that are a cutter (11%) and then little used sweeper (6%) and slider (4%). Part of me wonders if the Mariners are hoping to adjust his arsenal to try and get a hot second half out of him before opponents can figure him out.

If anything, this is a low-risk and high-ceiling move by the Mariners. They aren't losing anything from it, and if it works, it's going to be a nice addition to the pen at a low cost. Plus, how nice would it be to see a former Astros pitcher shut them down in the 7th inning when it matters most? Welcome aboard, Chris Devenski.
