The Tigers optioned Kreidler to Triple-A Toledo on Saturday.
Kreidler appeared in two games for the big club after being called up from Toledo on Monday, going 1-for-4 with a stolen base. For the season, he's slashing .136/.208/.205 with three stolen bases, one home run and two RBI across 48 major-league plate appearances. The move makes room on the Tigers' 26-man roster for Parker Meadows (hamstring), who was reinstated from the 10-day injured list.
