Seattle Mariners Recently Signed 37-Year-Old Former Stud Reliever to Minor League Deal

It's been quite a few years since Bryan Shaw was one of the top relievers in baseball, but the M's are giving him a shot to keep his career going. He debuted with the organization on Tuesday, giving up one run in 0.1 innings.

The Seattle Mariners recently signed veteran reliever Bryan Shaw to a minor league contract and assigned him to Triple-A Tacoma. He actually made his organizational debut on Tuesday night, giving up one earned run in 0.1 innings. He walked three and suffered the loss against the Las Vegas Aviators.

Shaw, 37, was once of the top bullpen arms in baseball, but it's been several years since he's seen that kind of productivity.

Debuting in 2011 with the Arizona Diamondbacks, Shaw was elite until the end of the 2017 season. He helped the Cleveland Guardians get to the World Series in 2016 and had a 3.13 ERA in 475 games from 2011-2017.

He then spent two years in Colorado, going 7-8 with a 5.61 ERA before throwing six games with the Mariners during the COVID 2020 season. He had an ERA of 18.00. Shaw went back to Cleveland for a solid 2021 season in which he appeared in 81 games (3.49 ERA), but he had a 5.40 ERA the following season. He spent 38 games with the Chicago White Sox in 2023 and pitched five more in 2024, owning a 4.53 ERA.

The California native began the year with the Cincinnati Reds organization, posting a 27.00 ERA in four apperances (1.2 innings).

Entering play on Thursday, the Mariners are 18-12 and in first place in the American League West. While Shaw doesn't figure to be high on the priority list for a call-up, the roster has been so besieged by injuries, that you never know how much depth you are going to need.

The M's are off on Thursday but will resume play on Friday at the Texas Rangers.
