Match ends, Huddersfield Town 1, Watford 2.
Gerard Deulofeu scored an impressive double as Watford kept their European ambitions alive with a comfortable victory over Huddersfield.
The Spaniard opened the scoring in the fifth minute and sealed victory late on, sending the Hornets up to seventh in the table.
For the first, Jonathan Hogg lost possession deep inside his own half before Terence Kongolo's recovering tackle knocked the ball into the path of Deulofeu, who guided it past Jonas Lossl.
Deulofeu cemented the win when he was on hand to convert from close range after Lossl parried Ken Sema's shot.
Huddersfield did salvage a late consolation, as substitute Karlan Grant capitalised on some tired Watford defending to head in from close range in the final seconds.
The already relegated Terriers remained rooted to the foot of the table, while Watford took a step closer to European football - and could yet qualify via the FA Cup.

Dominant Deulofeu a constant threat
Watford could have been forgiven for having one eye on their first FA Cup final since 1984, but Javi Gracia's side still produced a thoroughly professional performance in west Yorkshire.
Deulofeu - who came back into the side for the suspended Troy Deeney after missing the defeat at Arsenal because of injury - was unstoppable as the Terriers toiled in the sunshine.
The Spaniard struck an early blow with an excellent curling finish as Watford looked to improve on a run of three league defeats in their past four games.
Having taken the lead, the visitors enjoyed more controlled possession than their hosts, armed with the constant threat of Deulofeu who changed the intensity as and when he pleased.
Sema was impressive throughout with his driving runs from midfield but Deulofeu sealed the win with 10 minutes remaining when he guided the loose ball past Lossl after the Terriers' keeper saved Sema's fierce shot.
The Hornets will be disappointed not to have secured a clean sheet, but after Wolves and Leicester dropped points, the victory was enough to ensure they rose three places.
Huddersfield lack finish but show promise
The Terriers have had a disappointing second season, with their relegation to the Championship confirmed in March.
Goals have been the biggest issue for Huddersfield - the Premier League's lowest scorers - and they struggled with a clinical edge against the Hornets once more.
Jan Siewert's side had more shots (13) than their opponents (11) but only three were on target.
The hosts had their chances to draw level after Deulofeu's opener, but could only force opposition goalkeeper Ben Foster into one meaningful save.
The veteran showed his athleticism to keep out Isaac Mbenza's fierce effort from 25 yards with a smart save to his left.
However, Grant's fourth goal of the campaign saw him become the club's top goalscorer this season, as the Terriers moved level with Derby County's lowest Premier League tally of 20 goals in 2007-08.
Man of the match - Gerard Deulofeu (Watford)
'It will never stop hurting' - what they said
Huddersfield boss, Jan Siewert, speaking to BBC Match of the Day: "This is the frustrating thing but it always hurts when you lose games and it will never stop. I will stay positive because we have to learn from this season.
"In the 4-3-3 we started today, we were on the front foot against a team that are doing really well this season and we caused them problems and that's what we should take out of this game.
"We conceded too early and we know it's even harder to go. When you create so many chances against Watford who have a stable defence, it makes me proud.
"It's about taking chances which they did twice and it's hard to take."
Watford boss, Javi Gracia, speaking to BBC Match of the Day: "First of all I would like to speak about Huddersfield. Credit to them, it is not easy to play in this situation after their relegation.
"They tried. They made it very difficult today and it was a close game. We conceded in the last minute and in my opinion we had control of the game but we needed to kill it before the end and we didn't.
"I think Gerard [Deulofeu] is showing his quality. He's scoring more goals for us but always showed what he is able to do.
"It's important for the team for our players to score goals for us."
