Atlanta designated Stratton for assignment Wednesday.
Stratton will lose his place on the 40-man roster to make room for Jair Camargo, who was added to the active roster to work as the 27th man Wednesday. Stratton pitched a scoreless inning during his lone appearance with Atlanta this season and owns a 4.38 ERA and 1.65 WHIP across 24.2 frames at Triple-A Gwinnett.
