According to MLB Network’s Jon Morosi, the Mariners signed RHP Luke Barker to a minor league deal and assigned him to Triple-A Tacoma.
The 32-year-old Barker missed all of 2023 while rehabbing from Tommy John surgery. He debuted with the Brewers in 2022 and allowed five runs in four innings before suffering a UCL injury and then being released by the Brewers in August of that year. He has a career 2.32 ERA as a reliever at Triple-A and figures to operate as organizational depth for Seattle.
