That's full-time then and a huge boost for the Baggies. Sessegnon, Ridgewell and Amalfitano hand them their first win of the season, and condemn Sunderland to bottom place.
GOAL! Man of the match Amalfitano rounds off the win for West Brom, lashing home a strong strike to make it 3-0.
Sessegnon replaced by Saido Berahino as West Brom look to close out the game.
Ki Sung-Yeung is now down for Sunderland, it's not getting any better for Paolo Di Canio. He manages to return to the pitch however.
Amalfitano's deft cross created all sorts of problems for Sunderland there, and West Brom capitalised excellently.
GOAL! Ridgewell gets there first to a cross tipped away by Westwood, firing home to make it 2-0 as West Brom break on the counter!
Terrible news for Sunderland as Fletcher is stretchered off.
Altidore's great low cross finds Fletcher racing in, and you'd back the Scotsman in that situation but it flies just over. Worryingly for Sunderland, the striker is still down after falling awkwardly. All substitutions have been used.
For Sunderland, Cattermole replaces Gardner.
Sinclair and Anelka both head off to applause for West Brom, with Yacob and new-boy Anichebe coming on.
Anelka nearly doubles West Brom's lead with a deflected header.
Great move from Sunderland as Mavrias moves the ball out wide. The delivery is clever, finding Altidore who dropped off from his marker. His shot deflects just wide however, with shouts for a handball ensuing.
Frustration may be creeping in for Sunderland as Gardner's 25-yard effort flies well over.
Sessegnon seems to be trying to prove a point to someone, any idea who? A great turn and powerful effort flies just over.
On comes Jozy Altidore for the energetic but nonthreatening Fabio Borini.
The corner came to nothing, but Sunderland continue to apply the pressure. West Brom, as of yet, are standing firm.
Gardner's delivery flies in and takes a deflection off a Baggies player, so it's a Sunderland corner.
Sunderland, as aforementioned have come out of the blocks raging in this second-half. A free-kick on the edge of the 18-yard box awaits...
Mavrias has replaced Giaccherini in Sunderland's only half-time substitution. No changes for WBA.
Here comes the second half then, and Sunderland look fired up.
Jakob from the Faroe Islands is backing the Baggies to close out the win however: "i'm only going for 2-0 to West Brom, Anelka for the next, Sunderland have been terrible."
Jack Cary fancies the Black Cats to bounce back: "Sunderland are not out of this. If at half time they can pull themselves together like they did last week at home to Arsenal - and have luck on their side - they can still win this. I'm saying 2-1 Sunderland."
What are your thoughts on the action so far then? Which player has impressed you? Can West Brom consolidate their lead, or will Paolo Di Canio rally his troops for a second-half onslaught. You can let me know via Twitter @MattStead91, or by e-mail at Matthew.Stead@bskyb.com
West Brom head into half-time with a one-goal lead then after Stephane Sessegnon's first for the club against his former side. the Baggies have value for money too, with their front-four attacking players creating problems for Paolo Di Canio's men. Fabio Borini's looks lively, but a little isolated for the Black Cats.
Olsson and McAuley have been back to their imperious best for West Brom today, repelling almost every Sunderland attack as the Baggies' front four look particularly dangerous.
Borini has looked pretty lively up front for Sunderland and another lofted through-ball gives him the chance to race onto it. Myhill comes out quickly however to thwart him.
Lacklustre defence from Sunderland gives Anelka a chance to get an early cross in, but luckily Westwood is alert enough to get there first.
It did look as though Amalfitano's effort came off a Baggies shirt, but the corner is awarded nonetheless. Results in nothing.
Mulumbu finds Amalfitano in acres of space on the right. He cuts inside past one player, and his shot takes a deflection and skims the post for a corner.
The corner finds it's way into the hands of Myhill as West Brom survive a brief scare.
Sunderland get their chance as a low cross evades everyone but Johnson, whose effort goes narrowly wide via a deflection.
West Brom are now dictating the pace of the game after Sessegnon's goal, with Sunderland chasing shadows currently.
GOAL! Sessegnon reacts first after a Westwood close-range save to open his Baggies account. No celebration from the former Black Cat.
Brilliant work from new-boy Amalfitano as he cleverly evades one player and bursts forward from defence, but the opening still won't present itself for the home side.
Sunderland are starting to apply some real pressure but West Brom are sticking to a passing game, leaving plenty of their fans frustrated when clearing to safety seems the better option.
Giaccherini's free-kick heads straight into the wall and rebounds out.
Borini manages to get first to a loose ball, drawing the foul from McAuley. Free-kick from 20 yards coming up.
Both midfields are now cancelling each other out as each side attempts to carve out an opportunity.
A long ball over the top from West Brom this time puts Westwood under pressure as Anelka continues to pressurise him. He manages to snatch the ball quickly, but his heart will be in his mouth there.
Plenty of Sunderland bodies back for a couple of West Brom corners. Both are survived.
Sunderland have flown over a couple of long balls to Borini who seems a little isolated up front. Easily dealt with by the Baggies.
Quick start to the game and Fletcher signals Sunderland's intentions with a crunching midfield tackle.
And we're underway then as Sunderland kick us off.
West Brom are the 21/20 favourites to win today with Sunderland 13/5 and the draw 12/5. Stephane Sessegnon is 12/5 to net anytime against his former club while Nicolas Anelka heads the first goalscorer betting at 11/2.

Paolo Di Canio and Steve Clarke were both extremely busy in the transfer window however, with the Italian welcoming 14 players through the doors at The Stadium of Light this summer, while Clarke's main business came late on as Victor Anichebe and Stephane Sessegnon joined other notable additions in Scott Sinclair and Nicolas Anelka at The Hawthorns.
Both sides have started somewhat disappointingly in the Premier League this season, with Sunderland on one point, accruing just one less than the second bottom side in the Baggies.
Good afternoon and welcome to the live commentary of today's clash between West Brom and Sunderland at The Hawthorns.
