Chargois fired 1.1 perfect innings in a loss to the Rangers on Sunday, recording two strikeouts.
Summoned from Triple-A Tacoma earlier in the day in a corresponding move to Ljay Newsome's placement on the injured list, Chargois received an immediate opportunity to make his Mariners regular-season debut. The 30-year-old was logging his first game action since 2019 with the Dodgers and should see low-leverage opportunities akin to Sunday's during his time with the big-league club.
