The Diamondbacks optioned Morillo to Triple-A Reno on Wednesday.

EDGE Analysis

The 26-year-old's move to the minors will clear a spot on the active roster for Jake Woodford, who signed with the D-backs on Wednesday. Morillo has posted a 4.01 ERA and 1.54 WHIP across 24.2 innings in the majors this year, and he could return to Arizona later in the season if/when the Diamondbacks need a fresh bullpen arm.
