Candelario was optioned to Triple-A Iowa on Saturday, Gordon Wittenmyer of the Chicago Sun-Times reports.
He was sent back to Triple-A to open a roster spot for Munenori Kawasaki, who will add depth and a left-handed bat to the Cubs' outfield. Candelario couldn't quite make the adjustment to major league pitching during his brief call-up, collecting just one hit with five strikeouts in 11 at-bats.
