Vargas was recalled from Triple-A Reno on Thursday.
As expected, Vargas will break camp with the Diamondbacks after it was announced that Steven Souza (knee) would require season-ending surgery. The 27-year-old, who owns a .250/.273/.375 triple-slash across 33 PA and 26 games over parts of two big-league seasons, will likely fill a utility role for the big club.
