The Arizona Diamondbacks made the following roster moves:
- Selected RHP Peter Solomon from Triple-A Reno.
- Acquired RHP José Ruiz from the White Sox for cash considerations.
- Placed RHP Zach Davies (strained left oblique) on the 15-day injured list.
- Transferred RHP Mark Melancon (strained right shoulder) to the 60-day injured list.
- Transferred RHP Cole Sulser (strained right shoulder) to the 60-day injured list.
The arrival of an arm to replace Davies was entirely as expected, with Zach likely to be out of action for some time.
