Four goals at home and a rare clean sheet - it was a good day for Sunderland who gave their fans some much-needed pre-Christmas cheer.
The Black Cats moved out of the bottom three (albeit for a day) after a convincing display at the Stadium of Light.
Sunderland scored four here for the first time in nearly two years; and not since New Year's Day 2001 had the home crowd seen their team hit four at home in a Premier League match.
Kenwyne Jones opened the scoring in the 23rd minute, diving full stretch to head Andy Reid's right-wing cross past Scott Carson.
Jones made it 2-0 a minute later, tapping in after Carson had made good saves from Djibril Cisse and Reid. It took Jones' tally for the season to four - and he has only started five games.
Sunderland made it 3-0 just before half-time with a collectors' item - a Reid header. The diminutive midfielder scored at the back post after a good ball in from Steed Malbranque. There was no way back for Albion.
It was 4-0 just after the break when Cisse smashed a penalty past Carson after Roman Bednar, the substitute, had handled during a scramble in the box.

West Brom, who have now gone 10 League games without a victory, battled on until the end and on another day would have grabbed a consolation goal, but the league table paints a gloomy picture for them now.
There was nothing between the sides in a nervy opening 20 minutes before the game exploded into life as Jones opening the scoring with a header.
Less than a minute had passed when Jones scored again, and concending two goals so close togather was too much to take for the Baggies, who are rooted to the bottom of the Barclays Premier League.
Jones and Cisse were a constant menace to the Albion back-four and on this evidence their partnership is starting to blossom.
Cisse missed a good chance to score his second after the break and only a good save by Carson, who played well, denied Jones a hat-trick, the keeping stopping the big striker's shot with his outstretched leg before Reid blasted the rebound high and wide.
There were plenty of positives for Sunderland: a first clean sheet since October 18, an oustanding display from Teemu Tainio on his return to the side, a halt to their alarming home form and a first win for Ricky Sbragia.
This was a display of energy, flair and determination and was a far cry from their last home game, a 4-1 defeat by Bolton.
Sunderland might even have a chance when they visit the mighty Tigers of Hull next weekend!
