The Mariners optioned Simpson to Triple-A Tacoma on Wednesday, Shannon Drayer of SeattleSports.com reports.
Seattle called up lefty Jhonathan Diaz from Triple-A in a corresponding move, giving the Mariners a fresh arm in the bullpen. Simpson was unlikely to be available for another day or two after he needed 33 pitches to record two outs in his appearance during Tuesday's 22-0 loss to the Brewers. He gave up five runs on three hits and two walks in the outing, inflating his ERA to 9.82 and his WHIP to 2.05 over 7.1 big-league innings on the season.

The Mariners recalled Simpson from Triple-A Tacoma ahead of Sunday's game against the Twins.
Simpson has appeared in four games out of the Seattle bullpen this season, giving up three earned runs on four hits and two walks across three innings. He'll likely be in store for an abbreviated stay with the big club, as the Mariners will need to clear room on the 26-man active roster for the newly acquired Seranthony Dominguez prior to Tuesday's series opener with the Tigers.
