McFarland was optioned to Triple-A Norfolk on Saturday.

EDGE Analysis

The 26-year-old southpaw has a 4.73 ERA and just four strikeouts in 13.1 innings this year, so he was deemed expendable when the Orioles wanted to bring up Paul Janish to start at shortstop in Game 1 of Saturday's doubleheader. McFarland should continue to provide organizational left-handed relief depth.
