The Diamondbacks have found the roster spot for when Archie Bradley makes his start tomorrow afternoon. The team has announced that they have optioned reliever Dominic Leone to AAA Reno. No corresponding move have been made yet officially, although we know who it will be. There will be another move on Monday for Edwin Escobar, although I doubt Archie Bradley will be the unlucky soul to get shuttled to Reno.
With Shelby Miller and Rubby De La Rosa sent to the 15-Day DL, Bradley should make at least 3 starts in his current stint. De La Rosa's injury is a minor sprain of the UCL in his pitching arm, so it's possible that Bradley may be up for the rest of the season provided he pitches well. Dominic Leone has struggled in his time as a Diamondbacks pitcher, often pouring gasoline in the game with the team well behind.
