Cecconi was optioned to Triple-A Reno on Monday.
Cecconi was roughed up by the Orioles over the weekend and now finds himself back in the minors. It's not clear what the Diamondbacks plan to do with his rotation spot, but Arizona could look to bring back Ryne Nelson, who has pitched well over his last three starts at Reno. Cecconi holds a 4.44 ERA and 18:4 K:BB over 24.2 innings in the majors this season.
