Matt Phillips gave West Brom the lead after 29 minutes, but QPR drew level 5 minutes later through Joel Lynch.

The change came at half-time, and Albion began to dominate.

Kieran Gibbs scored his first goal for the club in minute 53.

Jay Rodriguez then netted a penalty two minutes later, as the Baggies began to run away with the game.

Newcastle loanee Dwight Gale also opened his goalscoring account in minute 67 and then won a penalty which was put away by Rodriguez.

Phillips was then able to score his second in minute 88, before Robson-Kanu rubbed salt in the wounds, scoring in stoppage time.
