Buchter failed to land a spot on the Mariners' Opening Day roster after inking a minor league deal earlier this month. The 35-year-old veteran southpaw struggled last year, but holds a strong 3.16 ERA, 1.22 WHIP and 259/115 K/BB ratio across 236 1/3 innings (285 appearances) in the majors since 2014.

The 35-year-old southpaw was released by the Diamondbacks back in August after registering a 6.61 ERA, 1.78 WHIP and 16/13 K/BB ratio over 16 1/3 innings. From 2018-2019 with the Athletics though, Buchter was one of the best left-handed relievers in all of baseball. It's a nice low-risk depth signing for the Mariners.

Buchter had been at Triple-A Reno after struggling during his time with the D-backs. He should be able to latch on somewhere else.

With Joe Mantiply returning from the COVID-19 injured list on Friday, the Diamondbacks jettisoned another left-hander from the bullpen. Buchter has struggled through 18 appearances with the Diamondbacks this season, posting a 6.61 ERA, 1.78 WHIP and 16/13 K/BB ratio over 16 1/3 innings.
