The Mariners designated Dugger for assignment Sunday.
EDGE Analysis
Dugger will forfeit his spot on the 40-man roster one day after being called up from Triple-A Tacoma and subsequently getting pummeled for six runs (five earned) on seven hits and two walks over 3.1 innings of long relief in Saturday's 15-1 loss to the Astros. Seattle will replace him in the bullpen with another multi-inning arm in Matt Andriese, who was signed to a one-year deal and added to the 40-man roster ahead of Sunday's series finale in Houston.
