The Mariners have signed right-hander Justin Grimm to their Triple-A Tacoma roster, according to a report from Rainiers broadcaster Mike Curto (Twitter link). Grimm has already been placed on Tacoma’s disabled list, which could indicate that he is still dealing with the shoulder impingement issue that led to his presence on the Royals’ disabled list earlier this season. Grimm was still on the DL when Kansas City released him earlier this month.
Between the shoulder injury and an earlier back problem that also required a DL stint, it has been a miserable year for Grimm both health- and performance-wise. The 29-year-old posted an ugly 13.50 ERA and 14 walks over just 12 2/3 innings out of the Royals’ bullpen. He had around $600K remaining on his $1.25MM deal at the time of his release, so the Royals will cover the bulk of that total, with the Mariners only owing him the prorated portion of a league minimum salary.
It wasn’t long ago that Grimm was a very useful relief arm for the Cubs, as he posted a 3.36 ERA, 10.6 K/9, and 2.66 K/BB rate over 171 1/3 frames out of Chicago’s bullpen from 2014-16. Given his low price tag, the Mariners can afford to take a flier on the veteran to see if he get healthy and regain any of his old form, which would give Seattle an extra bit of bullpen depth.
