Ryan Thompson Injury: Next step TBD

Thompson (shoulder) is scheduled to throw Friday after pitching a scoreless inning for Triple-A Reno on Tuesday, MLB.com reports.

The outing Tuesday was the first game appearance of a rehab assignment for Thompson. Following a live batting practice and a sim game, Tuesday's appearance was expected to be his final step before activation; however, the report indicates Friday's throwing session is the only confirmed next step in the process. The Diamondbacks may be waiting for September when rosters can be expanded be to 28 players (14 pitchers).
