The Mariners outrighted Raposo to Triple-A Tacoma. He's no longer on the 40-man roster but will remain in the organization as catching depth. Raposo, 26, has a career .241/.321/.387 slash line in the minors and has yet to see any action at the big-league level.
The Mariners designated Raposo for assignment Tuesday, Shannon Drayer of SeattleSports.com reports. The move frees up a spot on the 40-man roster for Miles Mastrobuoni, who was acquired via trade. Raposo was a waiver claim by the Mariners in December and will now go through the waivers process again.
The Mariners claimed Raposo off waivers from the Blue Jays on Thursday, Daniel Kramer of MLB.com reports. Raposo, 26, slashed just .206/.280/.340 with eight home runs over 78 games at the Triple-A level in the Cardinals and Blue Jays organizations in 2024. He's a defensive-minded catcher who will serve as organizational depth.
