The Diamondbacks optioned Abner to Triple-A Reno on Sunday.
Abner was called up to the big club Thursday after Taylor Clarke landed on the family medical emergency list. In his lone appearances with the Diamondbacks, Abner gave up five runs over 1.1 innings against Washington on Friday. Clarke was reinstated Sunday, so Abner will move back to Reno to open up a spot on the 26-man active roster.
