Riley (side) is out of the lineup for Friday's game against San Diego, Justin Toscano of The Atlanta Journal-Constitution reports.
Riley won't be starting for a fourth consecutive game as he deals with inflammation in his left side. Instead, Zack Short will draw another start at the hot corner and bat ninth. Atlanta manager Brian Snitker said that Riley is feeling better but isn't quite ready yet, per David O'Brien of The Athletic. He remains day-to-day.
