Farquhar was recalled from Triple-A Durham on Monday.
Farquhar was up with the Rays over the weekend, serving as the 26th man for Saturday's doubleheader against Baltimore. He was sent back to Triple-A following the two-game set but will now return to the bullpen, filling the roster spot vacated by Ryan Webb, who was DFA'd on Monday. Farquhar has conceded eight hits and three earned runs through 6.1 innings of major league work on the season.
