Tapia was optioned to Triple-A Las Vegas on Thursday, Martin Gallegos of MLB.com reports.
Tapia was recalled Tuesday and made one one appearance during his time on the roster, allowing two runs in 2.1 innings of relief Wednesday against the Mariners. He's now given up six earned runs in 3.2 major-league innings this season, which doesn't help his case for a return to the roster. Sam Moll returned from the COVID-19 injured list in a corresponding move.
