Rest-of-Season Projections
Signed a one-year contract with the Mariners in March of 2026.
Optioned to Triple-A
The Mariners optioned Castano to Triple-A Tacoma on Wednesday.
Analysis
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.

2025 Fantasy Outlook
An undersized (5-foot-10, 162 pounds) 26-year-old righty with no big-league experience, Castano was added to the Mariners' 40-man roster this offseason to protect him from the Rule 5 draft. Castano originally signed with the Yankees in 2018 out of the Dominican Republic but was released in 2023, which is when Seattle signed him. He split 2024 between Double-A and Triple-A, logging an excellent 53.5 percent groundball rate, but a mediocre 12.0 K-BB% in 125.1 innings. He only pitches out of the stretch and may make his big-league debut as a reliever, but Castano has enough pitches to be a back-end starter if injuries were to clear a path in 2025.
