The Reds recalled Soto from Triple-A Louisville on Sunday.
Soto has remained at Louisville since he was claimed off waivers from Baltimore in April, slashing .299/.393/.372 with 19 RBI across 191 plate appearances. He doesn't have a clear path to playing time in Cincinnati's infield, so he'll likely occupy the bench as a depth piece. Austin Wynns was designated for assignment in order to clear a spot on the active roster.
