The Reds made two other moves, placing outfielder Scott Schebler on the 10-day disabled list with a right ulnar nerve contusion and recalling right-handed pitcher Zack Weiss.
Schebler has not played since being hit by a pitch in the third game of the season April 1, and the roster move including him was retroactive to Friday. Weiss, who will also make his big-league debut when he pitches, was on the Opening Day roster but was sent to Louisville on March 31 when the Reds signed veteran pitcher Yovani Gallardo.
