The Twins optioned Kirilloff to Triple-A St. Paul after Wednesday's 17-9 win over the Rockies, Aaron Gleeman of The Athletic reports.
Kirilloff will head to Triple-A in order to get back on track after going 2-for-21 with nine strikeouts since the beginning of June, bringing his season slash line down to .201/.270/.384 through 178 plate appearances. The Twins have not yet announced a corresponding move for Kirilloff's demotion, but his absence will likely result in more time in left field for Trevor Larnach and more time at first base for Carlos Santana.
