The Diamondbacks called up pitcher Bradin Hagens Wednesday and optioned pitcher Andrew Chafin to Triple-A Reno.
Hagens has yet to pitch in the majors but owns a 4.12 ERA and 62:54 K:BB ratio in 115 2/3 innings between Double-A and Triple-A, with only five of those innings coming at the higher level. Chafin made the start for the Diamondbacks in Game 2 of Wednesday's doubleheader and will head to the minors to provide the team with extra bullpen help.
