Watford 0 West Bromwich Albion 3
Rampant West Bromwich Albion left manager Tony Mowbray purring as they swept aside Watford at Vicarage Road.
Watford side simply had no answers to Albion's goal-threat and possession play.
Mowbray felt the results underlined his side's battling credentials.
"It was a good test for us," he said. "We were very aware of what was coming and what was ahead of us and the players stood up to that.
"We got a very, very positive result and hopefully we can use that as a springboard to get perform-ances similar to that away from home all season. We've all got a strong belief at the club that if we trust each other with the ball and enjoy the way we play we will get results.
"We got our just rewards and I don't think anyone can say we didn't deserve to win. We still tried to play when we could and move the ball around when midfield.
"We know we've got quality at the top end of the pitch and Miller and Phillips keep scoring. When you've got quality play-ers at the top end of the pitch to take opportunities you've got a chance."
The Baggies started slowly but became stronger as the half wore on and, by the end of the game, could have won by four or five goals.
Ishmael Miller opened the scoring on 33 minutes when he reacted quickly after Kevin Phillips' shot was saved by Watford keeper Richard Lee. Phillips went from goal provider to scorer when he grabbed his ninth of the campaign following a two-minute spell of keep ball from the visitors.
And Martin Albrechtsen made sure of all three points when he headed home the third after the break to put the Baggies within six points of leaders Watford and just one point behind second-placed Bristol City.
John-Joe O'Toole had the first opportunity for the home side when he fired a shot just wide of Dean Kiely's post. Darius Henderson then headed Tommy Smith's cross straight at Kiely. The Baggies keeper grabbed the ball on the goalline despite frenzied appeals from the Watford fans that the ball had crossed the line.
But the home side's dominance quickly faded. The visitors took the lead just after the half hour mark when Miller flicked the ball on for Phillips, who raced past substitute Adrian Mariappa only to see his shot smothered by Lee. Luckily for Albion, Miller was quickest to react by bringing the ball under control and smashing his shot past two Watford defenders and into the empty net.
Two minutes later, Albion killed the game when Phillips applied the slightest of touches to James Morrison's shot.
The move had started long before then when Albion kept possession of the ball for a full two minutes, before Robert Koren released Paul Robinson down the left-wing. His cross was diverted by Zoltan Gera but only onto the bar. Morrison drove the rebound back towards goal, with Phillips applying the final touch.
Albion should have increased their lead in the 48th minute when Morrison's pass, intended for Miller, was cut out by ex-Albion target Danny Shittu.
But Watford's good fortune didn't last long when, less than a minute later, Albrechtsen powered in Jonathan Greening's free-kick to put the game beyond any doubt.
Ex-Albion man Nathan Ellington, given a less than cordial reception by the visiting fans, went closest to pulling a goal back but his long-range shot flashed just past Kiely's goal.
At the other end, Phillips, Gera and substitute Chris Brunt had chances to increase Albion's lead during the final throes of the game as Watford continually got caught on the break.
Mowbray's side should have got the fourth goal in the 86th minute when former Watford favourite Robinson's long cross was headed across the face of goal by Robert Koren.
As Roman Bednar, the Hearts striker making his Albion debut as a substitute following his move to The Hawthorns, prepared to pounce, Jordan Stewart managed to scramble the ball clear.
The victory brings Albion to within six points of leaders Watford and just one behind second-placed Bristol City.
Mowbray was also delighted to see Miller and Phillips take their scoring totals to nine goals each.
The Albion manager added: "They're building a relationship and have contrasting styles. As long as they keep scoring and working hard that's fine.
"I've also got a few frustrated strikers sitting behind them but if they keep scoring we'll keep them going.
"I don't think they are competing against each other but they seem to keep scoring every game and long may that continue."
