Before first pitch, Seattle announced a roster move: right-handed pitcher Blas Castaño was claimed off waivers by the Colorado Rockies.
Mariners PR confirmed the move via a social post, stating that Castaño has been claimed by Colorado. The team did not provide additional details beyond the waiver claim.
Castaño appeared in one game for Seattle last season, leaving the Mariners with a limited sample size of his major-league work prior to the move.
The Rockies’ waiver claim adds another bullpen shuffle for Seattle as it gears up for the second game of the series at T-Mobile Park.
Reaction on MLB social media to Castaño’s move was swift, with fans and analysts weighing in on what the acquisition means for both clubs and the Mariners’ bullpen depth.
Seattle will now focus on Tuesday’s game against the Athletics, aiming to rebound at home after Monday’s loss and maintain momentum in a tightly contested series.
