Overview
- The Mariners selected INF/OF Weston Wilson and designated INF/OF Miles Mastrobuoni for assignment on Friday, moving a right-handed hitter onto their active roster.
- Seattle made the change to counter a Red Sox slate that will feature three left-handed starters over the series, a matchup that favors a right-handed bench bat.
- Wilson was signed to a minor-league deal on June 14, played two games at Triple-A Tacoma, has prior big-league experience, is expected to start immediately, and is out of minor-league options.
- Mastrobuoni had been activated from the injured list about a week earlier, has also exhausted his options, and now enters the 48-hour waiver period in which he can be claimed, traded, or outrighted.
- The move is likely short-term: option status and upcoming matchups mean Seattle could reshuffle the bench after the Boston series, and his DFA highlights how utility players’ roster spots can change quickly when teams chase handedness and immediate lineup needs.
