Mariners signed LHP Rob Kaminsky to a minor league contract.
The Mariners find themselves in desperate need of left-handed pitching depth, especially at Triple-A Tacoma, so Kaminsky will get another shot in Seattle’s organization. The 28-year-old southpaw last appeared in the majors during the pandemic-shortened 2020 campaign when he made five relief appearances for the Cardinals. He made 39 relief appearances last year for Double-A Arkansas in Seattle’s system.
