West Brom 7 QPR 1: Baggies hit Steve McClaren’s point-less visitors for six in the second half
Rangers dropped to bottom as Matt Phillips struck twice against his old club and Jay Rodriguez netted two penalties
QPR were knocked for six in the second half and to the bottom without a point as West Brom romped up to third place.
New Rangers boss Steve McClaren must already be under pressure after this collapse and some outrageously-poor defending.
Matt Phillips netted twice against his old club and Jay Rodriguez tucked home two penalties, whilst left-back Kieran Gibbs and loan striker Dwight Gayle hit their first goals for West Brom.
Joe Lynch soon cancelled out Matt Phillips' 29th minute opener for the Baggies against his former club.
But Gibbs and Rodriguez from the spot netted shortly after the break to put West Brom in command.
Gayle, borrowed from Newcastle, made it four midway through that second period before winning a penalty converted by Rodriguez.
Phillips and Hal Robson-Kanu then struck in the final three minutes.
The Baggies should even have made their breakthrough seconds before Phillips was on target.
Harvey Barnes delivered a perfect cross from the left and Gayle only had goalkeeper Matt Ingram to beat.
But his side-footed low shot was too straight, enabling Ingram to beat it away.
The loose ball flew straight to Phillips who made no mistake with his low 16-yard shot that whistled past the stranded Ingram.
That looked set to be the signal for Albion to take a stranglehold on affairs but battling Rangers were soon back on level terms after central defender Kyle Bartley gave away a free-kick.
Luke Freeman floated a cross into the area and the powerful Rangers striker Matt Smith rose above the Albion defence to nod the ball into the path of Lynch, who made no mistake with a fierce close-range volley.
But any hopes that Rangers had of that signalling an upturn in their fortunes were quickly extinguished at the start of the second half.
The lively Barnes crashed a shot against the foot of the post, Gibbs tucking home the 10-yard rebound.
Rangers were still reeling when Albion made the game safe.
Gayle's surge into the area was ended by Josh Scowen bringing him down.
