Candelario was optioned to Triple-A Iowa on Thursday, Patrick Mooney of CSN Chicago reports.
Candelario saw his major league debut last season with the Cubs, but he was only able to collect one hit in 11 at-bats during his short-lived stint. He tried to force his way back to the majors this spring, but his .235/.278/.373 slash line across 51 at-bats wasn't quite enough to earn him a spot in the Cubs' overcrowded infield.
