McFarland has been recalled to serve as the 26th man for Saturday's doubleheader against the Rays.

EDGE Analysis

McFarland was optioned back to Triple-A last weekend, but he'll make what will likely be a brief return to add bullpen depth for Saturday's two-game set. In 21 innings for the O's this season, the left-hander has amassed a 5.14 ERA while striking out six and walking seven.
