Riley is out of the lineup for Sunday's game against the Phillies.
It's the fourth straight contest on the bench for Riley, who has a .169 average with a 41.5 percent strikeout rate in July. The Braves may simply be giving the 22-year-old some extra time off to help him reset, but if replacements Adam Duvall and Ender Inciarte perform well, he may find it difficult to find playing time.
