The team gave no reason for the move but specified that Votto, a six-time All-Star, is not on the 10-day injured list.
Votto, 36, is batting .259 with two home runs and five RBIs in seven games this season.
The move made room to activate right-handed pitcher Anthony Desclafani (shoulder) from the 10-day injured list. He was scheduled to start the first game of the doubleheader.
