The Diamondbacks recalled Abner from Triple-A Reno on Wednesday.
Abner failed to crack the Diamondbacks' Opening Day roster, but he'll report to the big club prior to Wednesday's game against the Brewers. In nine appearances in Triple-A, Abner has a 4.82 ERA, 1.32 WHIP and 7:3 K:BB across 9.1 innings. In a corresponding move, right-hander Andrew Hoffmann was optioned to Reno following Tuesday's game against Milwaukee.
