Blas Castano News: Optioned to Triple-A

Published on March 11, 2026

The Mariners optioned Castano to Triple-A Tacoma on Wednesday.

Castano has yielded five runs with a 3:3 K:BB over five innings in five Cactus League outings. The 27-year-old will likely begin the season in the rotation at Triple-A Tacoma, but if he gets another shot with the big club, it could be as a reliever.
