Seattle Mariners Sign Former Top Pitching Prospect

The Seattle Mariners have signed left-handed pitcher Rob Kaminsky to a minor league deal, adding him to their pitching depth in Triple-A Tacoma.

The 28 years old, has previously played for the Mariners' organization, and had 39 relief appearances for Seattle's Double-A affiliate in 2021.

He last appeared in the majors during the pandemic-shortened 2020 season making five relief appearances for the St. Louis Cardinals.

Kaminsky struggled with a 4.91 ERA and 1.47 WHIP during his time at Double-A Arkansas in 2022, but despite this setback, the Mariners have seen potential in him and want to give him another opportunity to develop his skills in their system.

Kaminsky became a free agent in August 2022 after being released by the Philadelphia Phillies, where he only had one relief appearance during the entire season.

However, he was considered a top prospect while with the St. Louis Cardinals a few years ago.

It remains to be seen how Kaminsky will perform in Triple-A and whether he'll be called up to the majors, but the Mariners are hopeful that he can contribute to the team's pitching depth in the near future. Photo Credit: Jeff Hanisch-USA TODAY Sports
