Cortes was placed on the 15-day injured list Friday, retroactive to Aug. 8, with a left rotator cuff strain.
Cortes just returned this past Saturday from a two-month absence due to a left shoulder strain and struck out eight of the 14 batters he faced in a strong four-inning start against the Astros. His shoulder is apparently still an issue, however, and the 28-year-old southpaw will be shut down from throwing for another month, per Brendan Kuty of The Athletic. This could wind up being a season-ending setback. Jhony Brito has been called up in a corresponding move and will presumably start in Cortes' place this weekend in Miami.
