The Reds placed right hander Johnny Cueto on the 15-day disabled list with a strained right lat. They called up right hander Justin Freeman from AAA Louisville to take his roster spot.
The club is likely to call up left hander Tony Cingrain from Louisville to make Cueto's next schedule start. No timetable was given on Cueto's return.
Ryan Ludwick was placed on the 60-day disabled list.
Freeman appeared in five games for Louisville. He allowed one run on five hits. He was a 32nd round pick in the 2008 draft. Freeman was 4-7 with a2.91 ERA and 16 saves last year at AA Pensacola.
