Farquhar was optioned to Triple-A Durham on Friday.
The Rays needed to clear a spot on the 25-man roster for Saturday's starter, Blake Snell, and Farquhar was the casualty. He has been fairly mediocre of late for the Rays, giving up two home runs over his last 3.1 innings, but he'll likely be back up in the bullpen at some point, as the Rays need all the fresh relievers they can get. With Alex Colome taking a firm hold on the closer job for now, Farquhar has very little value in most formats, even when he's up in the majors.
