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.

Optioned to Triple-A
The Mariners optioned Castano to Triple-A Tacoma on Friday.
ANALYSIS
Castano was added to the Mariners' 40-man roster in November, but he'll head back to Triple-A to begin 2025 after allowing five runs (four earned) over two innings during spring training. The 26-year-old righty turned in a 5.13 ERA and 1.41 WHIP with the Rainiers last season, and he'll likely need to improve upon those numbers before getting a chance in Seattle's rotation.
