Tapia was optioned to Triple-A Omaha on Tuesday, Alec Lewis of The Athletic reports.
Tapia struggled with his control this spring, surrendering five runs on eight hits and six walks while striking out one batter over 5.1 innings in seven appearances. The reliever was an effective bullpen option for the Mariners and Royals last season, posting a 2.67 ERA and 1.19 WHIP. He'll look to recapture his control from 2021 while in the minors and return to the big leagues at some point in the coming weeks.
