Braves placed C Evan Gattis on the 15-day disabled list, retroactive to June 28, with a bulging thoracic disc in his back. There's no clear timetable for his return, but we should know more depending on how his back responds to an epidural injection. Juan Jaime will take his place on the active roster while Christian Bethancourt figures to see plenty of playing time behind the plate during his absence.
