The Seattle Mariners announced today that they have selected RHP Blas Castano from Triple-A Tacoma and added him to their 40-man roster. Additionally, they have reinstated RHPs Matt Brash and Jackson Kowar, along with UTIL Sam Haggerty, from the 60-day injured list. The moves bring the 40-man roster to a full 40.
The return of Brash, Kowar, and Haggerty are procedural, with Brash and Kowar on track seemingly to return to full health sometime between Spring Training and the first half of the 2025 season. Players cannot be kept on the injured list until Spring Training’s outset.
