The Diamondbacks recalled Abner from Triple-A Reno on Thursday, John Gambadoro of Arizona Sports 98.7 FM reports.
Abner has permitted seven runs with a 4:4 K:BB over 6.1 innings in his three appearances in the majors this season. The 24-year-old gives the team a fresh bullpen arm as the Diamondbacks downshift to four starting pitchers on the roster heading into the All-Star break.
