Aoki was optioned to Triple-A Tacoma after Friday's game, the Seattle Times reports.

EDGE Analysis

Since coming back from Triple-A on July 20, Aoki batted .316/.362/.429 with nine doubles, a triple, 11 runs and two stole bases. Almost all of his at-bats, though, came against right-handers (85 of 98) as he's been futile against left-handers this year (.207/.277/.228). In the next 10 days, the Mariners are scheduled to face six left-handed starters, which meant he'd be mostly sitting. So, the Mariners decided to use his roster spot to add a bullpen arm. Expect Aoki to be back in a couple weeks.
