The Diamondbacks recalled Carrillo from Triple-A Reno on Tuesday.
Carrillo was added to Arizona's 40-man roster Saturday, and he'll now get an opportunity to pitch for the big club following Drey Jameson's (hip) move to the injured list. Carrillo has put up a 4.15 ERA, 1.32 WHIP and 57:28 K:BB across 43.1 innings at Reno, and he'll be making his MLB debut whenever he gets into a game.
