West Brom moved four points clear of the Premier League relegation zone as goals from Brown Ideye and Saido Berahino secured victory over Swansea.
Ideye, who was close to joining Qatari club Al Gharafa on transfer deadline day, opened the scoring with a low shot – his second goal in two games.
He then turned provider, cutting the ball back for strike partner Berahino to slot home from 12 yards.
The result moves the Baggies up to 14th, while Swansea remain ninth.
West Brom made three changes to the side that fought back from two goals down to secure a 2-2 draw at Burnley on Sunday. The introduction of top scorer Berahino and club record-signing Ideye from the bench was key to that turnaround and manager Tony Pulis opted to start with the strike duo at The Hawthorns.
Ideye has struggled since making a £10m move from Dinamo Kiev last summer, but he showed signs his partnership with Berahino could blossom when the duo cleverly combined to earn a corner and provide the Baggies with the first chance of the game.
Both of West Brom’s goals against Burnley had also come from corners but on this occasion goalkeeper Lukasz Fabianski was equal to Craig Dawson’s near-post flicked header and palmed away Albion’s best chance of the first half.
Swansea’s best threat came from hard-working lone striker Bafetimbi Gomis, who fired a difficult chance at the near post over the bar before providing Garry Monk’s ponderous side with their first shot on target in the 40th minute – a volley straight at home keeper Ben Foster.
Gomis, who had spent much of the campaign as second choice to Wilfried Bony, has failed to find the net in six starts since the Ivorian’s £28m move to Manchester City last month.
And while Swansea continued failed to trouble Foster after the break, West Brom’s new strike pairing of Ideye and Berahino continued to threaten.
First, Berahino played in Nigerian Ideye, who swivelled on the ball and fired into the corner to open the scoring on 60 minutes.
Ideye then set up his strike partner 14 minutes later to secure all three points for West Brom, who have now lost just once in seven matches since Pulis’ appointment on 1 January.
With time running out for Swansea, Gomis squandered a further chance to end his goal drought when he headed over from the penalty spot. The 29-year-old has not scored since January’s FA Cup victory at Tranmere, while his only Premier League goal came in November’s victory against Arsenal.
