The Diamondbacks recalled Del Castillo from Triple-A Reno on Saturday.
After being sent down to Reno on July 6, Del Castillo will now return to the majors as the replacement for Lourdes Gurriel, who landed on the injured list Saturday with an adductor strain. Del Castillo has slashed just .185/.244/.311 across 164 plate appearances with Arizona this season, but he could receive some starts at DH or catcher while Gurriel is on the shelf.
