A bizarre goal by Tom Cleverley set promotion-chasing Watford on the way to a 2-0 Championship victory at home to mid-table Huddersfield.
The midfielder opened the scoring in the 54th minute by charging down Ryan Schofield's clearance straight into the Terriers' net, after the goalkeeper had reacted far too slowly to a backpass.
Joao Pedro doubled the lead 10 minutes later as the Hornets moved above Reading and into fifth place in the table.
Watford had handed a first league start to goalkeeper Daniel Bachmann after Ben Foster was ruled out by a finger injury.
Huddersfield, with almost a whole team sidelined, gave Newcastle loanee Rolando Aarons a full debut.
Just 10 minutes had passed before the game had its first shot of value. Joao Pedro launched the ball from 12 yards after Ismaila Sarr's cross had fallen to him but Schofield dived to parry.
The visitors were fortunate when Sarr won a free-kick that Cleverley lofted on to the head of Adam Masina in the box, but no Hornet had anticipated the knock-down.
Kiko Femenia then scudded a cross from the right across goal as the half continued to lack any quality in the final third.
The Terriers were superior in the passing stakes but Watford's more direct approach saw Schofield rush out to boot away before the pacy Sarr could pounce.
The hosts' frustrations manifested themselves in a booking for captain Troy Deeney for a recklessly-late challenge on Juninho Bacuna in front of the Town dugout.
It was not until two minutes before the break that the game's second shot was fired, again at Schofield, who dived to make a similar stop, this time to deny Sarr.
Huddersfield's first shot came in the 53rd minute but Bacuna's 20-yard effort was always on the rise.
Cleverley opened the scoring a minute later thanks to a moment of catastrophic indecision from Schofield.
Alex Vallejo - making his first Championship start - passed the ball gently back to his goalkeeper, who dithered so much that Cleverley was able to charge down the eventual clearance attempt into the net.
Watford doubled the lead through Joao Pedro, who converted Femenia's ball across goal at the back post after Sarr and a defender had both failed to get a touch. It was the teenage Brazilian striker's sixth league goal of the season.
Substitute Scott High forced Bachmann into his first and only save of the afternoon with 12 minutes remaining before Hornets replacement James Garner was only just too high at the other end.
What the managers said...
Watford's Xisco Munoz: "Tom is a perfect example of what we need - the passion every time to win the ball. This is our way and our fans will be happy with Tom.
"We had control of the game and the ball and I am happy with the players. The first half was difficult but in the second we made more chances."
Huddersfield's Carlos Corberan: "There is no doubt that Ryan Schofield is involved in the action, Alex Vallejo is also involved, but this is what it is like to play football. We need to keep our concentration in the key moments of the game. If you don't have the right concentration in the moment, you don't make the right decisions. You will suffer the consequences as any mist ke is going to have a high impact.
"I do not expect him to apologise. I was talking to my players after the game like I always do. I try to help them in my way. Ryan has everything to play in the Championship, that is why he is our first goalkeeper right now. We started the game the way we wanted to play but the team didn't create enough chances. The team did completely well until we gave one goal to them. After we gave this present to them it was impossible for us to win the game but the team did not give up at any moment."
