ALBION were finished-off by two second-half strikes at Crystal Palace in the lunchtime kick-off at Selhurst Park.
The Baggies' resilience kept them in the game during the opening half but the Eagles got their deserved opener midway during the first-half through Yannick Bolasie.
Yohan Cabaye made sure of the victory during the final throes when he converted a penalty after Chris Brunt had brought down Wilfried Zaha.
There was little for the 1300 Albion fans to get excited about in a game the home side dominated.
Saido Berahino whipped an early ball over Wayne Hennessey's bar after Palace failed to clear a Dawson cross. But it was the hosts who were to have the first attempt on goal when Yannick Bolasie cut in from the left-hand side only to shoot straight at Boaz Myhill.
James McClean also fancied his chances. His 11th minute strike was rising as it cleared the Palace bar but his invention and nifty footwork had enabled him to drift past Souare and Hangeland without any dramas.
Palace enjoyed a spell of pressure for the subsequent 15 minutes, without really testing Myhill's resolve.
Jonny Evans' afternoon, meanwhile, didn't last long. He was forced off after 24 minutes due to injury, being replaced by James Chester.
Myhill was called into action once more, just after the half hour mark, when he picked out Cabaye's long-range shot. Albion were hanging on.
Palace were asking more and more questions of their opponents. Zaha shuffled past Brunt on minute 37 only to see his effort parried by Myhill. The corner was cleared.
There was a further change for Albion - Craig Gardner came on for Berahino at half-time.
Palace continued to pick away. There were calls for a penalty early in the second half when a free-kick appeared to strike Gardner's arm.
But the Eagles got their reward in the 68th minute when Bolasie stretched out to reach Cabaye's cross and head home from close range.
And with two minutes left Palace doubled their lead when Zaha was deemed to have been brought down by Brunt prompting Jon Moss to point to the spot. Cabaye converted his penalty.
