Watford secured a crucial 2-0 win over West Brom at Vicarage Road on Tuesday evening.
A couple of goals to the good after 50 minutes, The Hornets had to dig deep in the final half an hour after Miguel Britos was sent off for a harsh second yellow card.
M’Baye Niang opened the scoring in the first-half with a spectacular strike before captain Troy Deeney extended the lead just after the break.
The win leaves Walter Mazzarri's men in ninth place in the Premier League with eight games to go, the bottom three seeming that bit further away.
The Head Coach made two changes to the starting line-up as Troy Deeney and Sebastian Prödl returned to the starting XI. Under-18 prospect Dion Pereira was also named on the Watford bench for the first time.
The Baggies were inches away from racing into an early lead as Nacer Chadli was released inside the box. The midfielder was thwarted by Gomes and couldn't poke the rebound home from a tight angle.
But it was the Hornets who took the lead. Deeney flicked a header wide to Niang, and the Frenchman cut inside before hammering a shot into the far-corner to put his side in front.
Mazzarri’s side were looking confident in possession and almost extended their lead midway through the half as Britos headed just wide from a Tom Cleverley corner.
As half-time approached Chadli again went agonisingly close to scoring for the visitors. The midfielder hit a sweet free-kick, which shaved the outside of the woodwork, much to the relief of Gomes in goal.
It was another forced first substitution for Mazzarri as Prödl appeared to pull something in first-half added time. Daryl Janmaat came on in his place.
Chris Brunt tried his luck from range moments into the second-half, but his strike was always rising and failed to test Gomes.
The Hornets extended their lead just two minutes later. An exceptional first-time ball over the top of the defence by Niang set Deeney away. The captain, with a lot still to do, poked in through the legs of the onrushing Ben Foster.
Chadli should have then done better after being played in at the back-post but he made a hash of things, volleying wide first-time.
The Hornets had Niang in fine form as he was a constant threat down the flank. He would have scored his second of the game but for an excellent block by Jake Livermore inside the box.
But it was not all plain sailing as the Hornets were recuded to ten men on 65 minutes.
Salomón Rondón broke clear and Britos was adjudged to have pulled him back. Referee Paul Tierney showed the defender a second yellow, much to the bemusement of those inside Vicarage Road.
Mazzarri made his second change of the game just a minute later as he looked to shore up the defence. Amrabat was replaced by Adrian Mariappa, whose nous and defensive strength was there for all to see.
The final change of the game came with just over ten minutes left to play as Isaac Success came on for the impressive Niang.
It was a tense finale but the Hornets held firm and ensured they recorded back-to-back wins at Vicarage Road.
