The Pirates have claimed Marlins' pitcher Hayden Penn off waivers. Penn is out of options, so he must be placed on the 25-man roster. A corresponding roster move must be made to make room for him on the 40-man as well.
UPDATE (3:20 PM): Jen Langosch reports that the Pirates have designated Brandon Moss for assignment.
