The Diamondbacks optioned Cabrera to Triple-A Reno on Tuesday.
The right-hander fired three scoreless frames out of the bullpen Monday in Kansas City and will now be sent down in favor of a fresh bullpen arm. Cabrera has made seven appearances (five starts) for the Diamondbacks this year and has a 4.33 ERA, 1.37 WHIP and 18:10 K:BB across 27 innings.
