Mariners' Nick Raposo: Booted from 40-man roster

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.
