The Diamondbacks optioned Cabrera to Triple-A Reno on Thursday, John Gambadoro of Arizona Sports 98.7 FM reports.
After tossing five scoreless innings in his major-league debut, Cabrera has given up 11 runs with a 9:7 K:BB covering 12.2 innings over his last three starts. With Cabrera back in the minors, it appears the Diamondbacks intend to keep Brandon Pfaadt in their rotation.
