QPR's chances of avoiding Championship relegation suffered another setback as two goals by Jake Livermore gave Watford victory at Loftus Road.
The former Hull, West Brom and England midfielder curled the ball beyond Asmir Begovic from 25 yards on the hour mark, and then drilled in his second from outside the box after a clearance from Matheus Martins' cross fell invitingly to him.
It was only the second time in the 34-year-old's career that he had scored more than once in a game - his first double came for Hull against Rotherham in 2016.
Sinclair Armstrong carried the main threat for Rangers but it was Lyndon Dykes who reduced the deficit when he stabbed in substitute Paul Smyth's cross from close range.
