Jordany Valdespin was designated for assignment to make room for Conley on the 25-man roster.
MIAMI -- Mat Latos is out for at least one start. The veteran right-hander was hit by a line drive in the dugout on Friday night and will be scratched from his scheduled Saturday outing. Adam Conley will make the start against the Reds in his place.
"It's a right foot contusion," Manager Dan Jennings said. "Conley will make the start. There was a ball last night that hit the net. Latos had his foot there and the ball struck him in the foot.
