Elder was recalled from Triple-A Gwinnett to start Saturday's game against the Marlins.
Elder was sent down in mid-August following a dominant start, but he'll rejoin the big-league club to start Saturday's game on short notice after Jake Odorizzi (arm) was scratched. During his start against the Marlins on Aug. 14, Elder allowed just one run on three hits and three walks while striking out 10 in seven innings.
