Diamondbacks' Christian Walker: Lands on 60-day disabled list

Walker was placed on the 60-day disabled list with a facial fracture Saturday.

Walker suffered the fracture when getting hit in the head by a pitch Monday. The move doesn't have any effect on his return date, as he's already been ruled out for the year, but it clears space on the 40-man roster for Shelby Miller (elbow) to be activated in a corresponding move.
