Farrell slotted over two penalties to Jimmy Gopperth's one to give the London club a 6-3 lead at half-time
Elliot Daly and Gopperth added further penalties either side of another successful kick from Farrell to level the match at 9-9, but the visitors then took charge with two tries in quick succession.
