Atlanta will option Elder to Triple-A Gwinnett on Wednesday, Justin Toscano of The Atlanta Journal-Constitution reports.
Elder had a tough time keeping the Brewers off the scoreboard during his spot start Tuesday, allowing seven earned runs on eight hits and two walks while striking out six batters in 3.2 innings. He now owns a 6.52 ERA and 1.63 WHIP through 49.2 innings in the majors this year, and his demotion to Triple-A could allow Grant Holmes to stick around in Atlanta's rotation until Reynaldo Lopez (forearm) is able to return from the injured list.
