Rest-of-Season Projections
Signed a one-year contract with the Mariners in March of 2026. Claimed off waivers by the Rockies in April of 2026.
Headed back to Triple-A
Castano was optioned to Triple-A Albuquerque after Sunday's doubleheader sweep of the Mets.
Analysis
Castano was called up to serve as Colorado's 27th man ahead of Sunday's pair of contests in New York, but he didn't appear in either victory. The right-hander will now return to the Triple-A level, where he's posted a 1.23 ERA and 0.68 WHIP with five strikeouts over seven appearances with Triple-A Tacoma and Triple-A Albuquerque so far this year.

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.
