West Brom celebrate making it 2-0 through Mikey Johnston's first goal since 22 December
West Brom held on to end their five-match winless run and boost their flagging play-off bid with a victory over Watford.
The home side took the lead inside the first 15 minutes when striker Karlan Grant finished well for his first goal since 29 December after great work by Tom Fellows.
Edo Kayembe came close to a leveller for the Hornets before the break but saw his long range shot come back off the post.
Mikey Johnston put Albion in control with a poked finish from another Fellows assist but Moussa Sissoko pulled one back after Will Lankshear and Isaac Price missed chances to put the game out of sight.
Tony Mowbray's side are now two points off sixth-placed Coventry, albeit having played a game more than the Sky Blues, who they visit on Good Friday.
A 12th away defeat of the season all-but ends the 11th-placed Hornets very slim play-off aspirations.
The home side came into the game in desperate need of a win after a run of three successive defeats had seen them drop out of the top six.
They made the perfect start when Fellows beat his man down the right with a clever drop of the shoulder before teeing up Grant to confidently sweep home.
Kayembe struck the woodwork from range, just as he had in Tuesday's 1-0 home win over Hull City, as Watford looked for a way back into it before the break.
Former Celtic winger Johnston scored seven goals in 20 league games on loan at West Brom last season but has struggled to replicate that form since joining permanently in August. However, he netted his third of the season, and first since 22 December, on the hour-mark with a nice left-footed finish.
Tottenham loanee Lankshear should have made it 3-0 but missed from close range and Watford goalkeeper Egil Selvik then made a good save from Northern Ireland international Price.
The visitors made Albion pay for their profligacy when veteran Sissoko finished expertly after a wonderful outside of the boot through ball from Imran Louza split the home defence.
Watford did not really have any chances to complete the comeback though and Selvik was forced into a fine late stop by Grant.

West Brom boss Tony Mowbray told BBC WM:
"I think the three points is the most important thing, I didn't particularly like our performance.
"I prefer to dominate the game and have double the shots of the opposition. It was a strange game today, they're a hugely athletic team and gave us some problems and yet I always felt on transitions there was a lot of space for us to play into.
"Two cutback goals is brilliant because we've worked on that a lot in the past 10 days.
"After the Sunderland game where we had over 60% possession and over 20 shots and lose 1-0, I said to the players do they want to be the dominant team or do you want to defend deeper and leave some space to counter-attack. It was interesting for me to see how quickly we could break away. It's food for thought moving forward."
Watford boss Tom Cleverley told BBC Radio 3CR:
"It was a good game of football and I knew it would be. It was high quality and we probably had more control but they had more clinical and effective moments.
"We've got some exciting young players who can maybe develop into how much quality they showed in front of goal today.
"They were outstanding in transitions today and they're not a transitions team because Tony likes to dominate the ball and rotate. Today we had control of the game and they were devastating on transitions and that's where tactical fouls can be effective.
"The performance levels in the last 10 games have not reflected the results."
