The Diamondbacks recalled Abner from Triple-A Reno on Wednesday, Jody Jackson of Bally Sports Arizona reports.
As expected, Abner will rejoin the Diamondbacks bullpen in a move that corresponds with Arizona playing right-hander Ryan Thompson (back) on the 15-day injured list. Abner has spent most of this season in Triple-A, where he has a 4.60 ERA and 1.19 WHIP across 31.1 innings. He's appeared in five major-league games for the Diamondbacks and has not allowed a run over his last three outings (spanning 5.2 innings) in the big leagues.
