Watford extended their undefeated run to five matches as they eased to a 2-0 victory over 10-man Bristol City.
Former Hornets keeper David James gave his old club an early lead, punching Carl Dickinson's ball into his own net.
Teenager Sean Murray then doubled his side's advantage on 20 minutes, scrambling in a loose ball after James saved from Troy Deeney.
The hosts pushed for a foothold in the game, but their challenge ended when Liam Fontaine saw red late on.
City started the match the brighter, Stephen Pearson firing over before Brett Pitman's 25-yard free-kick tested Tomasz Kuszczak.
But they were to go behind in disastrous fashion on 15 minutes, when James misjudged Dickinson's clearance and contrived to punch the ball into an empty net.
Five minutes later and Watford were two up, Murray slotting home his third goal in four games.
Ricky Foster almost pulled one back just before half-time, but saw his left-footed volley smartly saved by Kuszczak.
The Polish keeper twice saved from Albert Adomah in the second half, before tipping wide Yannick Bolasie's shot.
But the contest was effectively finished when captain Fontaine brought down Jonathan Hogg and was sent off with just over 10 minutes to go.
Bristol City boss Derek McInnes:
"The first was a killer goal from our perspective because we had started brightly.
"A mistake like that is something you cannot anticipate and the game ran away from us.
"The red card was a mistimed, rather than a reckless tackle. The ref had a decision to make and I think he made the wrong one. We will appeal."
Watford boss Sean Dyche:
"I saw the incident clearly and it was definitely a red card under the current rules. When I was playing it might have been different.
"You don't wish a mistake like the one David James made on anyone, but something like that happened to us in our home game with City so it balanced out.
"We can consider ourselves safe from relegation now with eight games to go and that is a good feeling. There were a lot of people ready to write off the club and me at the start of the season so I'm delighted with how we have done."
