Baggies keep Rangers in danger
West Brom midfielder Graham Dorrans added to QPR's relegation fears with a superb goal in a 1-0 win at the Hawthorns in the Barclays Premier League.
The Scotland international settled the contest midway through the first half with a 30-yard strike.
But QPR should have picked up at least a point with Bobby Zamora causing plenty of problems but spurning several opportunities.
QPR started brightly and Zamora went close to putting them ahead after only two minutes. The England striker found himself with only Ben Foster to beat after the ball ricocheted invitingly into his path. But Foster was alert to the situation and came quickly off his line to block the shot at the expense of a corner.
The only goal of the game came from Dorrans after 22 minutes. The Scotland international received the ball from Peter Odemwingie 30 yards out and his rising shot flew past QPR keeper Paddy Kenny into the roof of the net.
Zamora should have levelled after 39 minutes when he found himself with a free header from a pinpoint Joey Barton cross - but angled it just wide.
Foster then beat out a fierce drive from Zamora, who had worked under Albion coach Roy Hodgson at Fulham.
Albion came close to doubling their lead five minutes later when Odemwingie's reverse pass picked out the run of Billy Jones, whose low shot hit the base of a post.
Zamora's unhappy day continued when he was found in space by Adel Taarabt inside the Baggies box but sliced his shot, which hit the back of Jamie Mackie.
Kenny had to be alert to hold a dipping 25-yard free-kick from Chris Brunt away to his left, before Shane Long should have made it 2-0 in injury-time only to shoot wide.
