Match ends, West Bromwich Albion 1, Huddersfield Town 2.
Bottom-of-the-table West Brom were booed off by their fans after they lost again to fellow strugglers Huddersfield at The Hawthorns.
West Brom have won just once in 14 Premier League games under Alan Pardew and remain seven points adrift of safety, while Huddersfield move up three places to 14th.
The Terriers went ahead early in the second half through Rajiv van la Parra, and doubled the lead when Steve Mounie struck before the hour.
Craig Dawson headed in a Chris Brunt corner to halve the deficit and went close at another set-piece late on.
After winning the first two games of the season under Tony Pulis, the Baggies have won just once in 26 league outings.
Two consecutive league wins have given a timely lift to David Wagner's Huddersfield side, who are three points above the relegation zone.
After absorbing West Brom's early pressure, Huddersfield looked comfortable and had the best chance of a quiet first half when Alex Pritchard's on-target shot hit Mounie inside the penalty area.
But after going two goals ahead, Huddersfield's confidence was shaken when Dawson beat keeper Jonas Lossl to a corner to give the home side hope.
Lossl had some more nervous moments at further corners, but pulled off an excellent save high to his left to deny Brunt at a free-kick.

West Brom's misery continues
Last weekend's defeat at home to Southampton in the FA Cup - in the immediate aftermath of the incident involving four of their players and a stolen taxi - provoked grumbles from some West Brom fans.
But yet another loss in the Premier League proved too much for many more, with some heading for the exits when Mounie doubled Huddersfield's lead.
Their side had started well and forced some early half-chances for Jay Rodriguez and Salomon Rondon, raising hopes a corner had been turned.
But the defensive frailty that has blighted their season returned when the ball bobbled across the box to fall for Van la Parra, although the Dutchman's scuffed finish was symptomatic of a scruffy game to that point.
Although the closing stages were tense, the home side were often pegged back and had few answers to their attack-minded visitors.
In a dispiriting end, boos could be heard from many parts of The Hawthorns from fans worried that the 10 games left in the campaign may not be enough to preserve their top-flight status.
Huddersfield revival continues
A run of eight games without a win had led to Huddersfield's promising start to their first season in the Premier League tailing off into a worrying slide back towards the Championship.
But the 4-1 win over Bournemouth that earned three vital points a fortnight earlier needed a positive follow-up, and there had even been encouraging signs in the 2-0 FA Cup defeat by Manchester United a week earlier.
Wagner's side were without the injured Aaron Mooy, but even shorn of the Australian's energy and creativity they proved to be a handful for their hosts after weathering the early storm.
Pritchard, signed from Norwich in January, made a crucial contribution when his deft touch wrong-footed the defence and gave Mounie the chance to curl the ball around Ben Foster.
They continued to attack even after Dawson's goal, with striker Laurent Depoitre replacing the impressive Alex Pritchard when a defensive substitution may have been expected.
Following next Saturday's trip to Wembley to face Tottenham, the Terriers' next three league matches are against sides currently below them in the table, reviving expectations that Huddersfield might make it to a second season in the elite.
Man of the match - Alex Pritchard (Huddersfield)
What the managers said
West Brom manager Alan Pardew: "I think it is three wins in 37 games. It is a problem, we just have to find a way to win a game, however ugly it is. It was certainly ugly today.
"I was disappointed with the performance. We worked hard this week and looked good going into the game but it wasn't reflected in the game.
"Huddersfield knock you out of any rhythm with the way they play and it was a bitty game. We didn't really have any passages of play. We have two or three flair players missing but we should have had enough to beat Huddersfield really."
Huddersfield manager David Wagner: "We said this before, it wasn't a six-pointer but it was a massive game for us and the players showed everything - fighting spirit and attitude.
"It was a final for both teams, we won it and of course I am delighted and happy for the supporters, the players and staff.
"We expected they would be on the front foot. We overcame the first 10 minutes without us conceding a goal. After that it was open, we scored two wonderful goals and kept them as far as possible from our goal."
