Reds placed 3B Scott Rolen on the 15-day disabled list with a strained left shoulder.
Mike Costanzo has been recalled to take his place on the active roster and could share time at third base with Todd Frazier. Rolen is off to a rough start this year offensively, batting just .174/.238/.304 with two homers and 11 RBI. He could be out for an extended period of time.
