A bullet header from Billy Sharp gave Sheffield United a 1-0 win over bottom side Norwich City to lift the Blades to sixth place in the Premier League table and move them closer to their dream of European football next season.
The hosts took the lead in the 36th minute when John Lundstram crossed for an unmarked Sharp to plant a firm header past Tim Krul, and they could have had a couple more before the break as Norwich struggled to match their intensity.
Norwich bolstered their attacking options at the break by sending on Josip Drmic to partner Teemo Pukki, and Drmic came close to scoring when his shot deflected off David McGoldrick and bounced off the crossbar in the 75th minute.
The visitors continued to throw everything forward in an effort to find an equaliser, but United keeper Dean Henderson pulled off a string of fine saves, prompting the home fans to chant for him to be made "England's number one".
Newcastle United leapfrogged Southampton and moved up to 13th with a 1-0 win at St Mary's Stadium, thanks to a solo second-half effort from French winger Allan Saint-Maximin.
Southampton struggled to get a foothold in the game after they were reduced to 10 men when winger Moussa Djenepo made a reckless challenge to get sent off in the 28th minute.
Djenepo was initially booked when he caught Isaac Hayden above the ankle but the VAR advised referee Graham Scott to take a second look on the pitchside monitor, after which a red card was produced.
With Southampton a man down, it was down to Alex McCarthy to deny the Newcastle players on numerous occasions - particularly Dwight Gayle who had three shots on target blocked - and the goalkeeper finished the first half with six saves.
But McCarthy could do nothing when Saint-Maximin pressed Yan Valery, pinched the ball from his fellow Frenchman and then toe-poked the ball off the post for his second goal of the season to give Newcastle their first league win since January.
Crystal Palace extended their winning run and moved into the top half of the standings with a 1-0 win over Watford, thanks to a first-half goal from Jordan Ayew at Selhurst Park.
It was Palace's third consecutive league win after a winless seven-game run and it moved Roy Hodgson's side up to 10th in the standings.
Ayew gave Palace the lead with their first shot on goal when James McArthur created an opportunity for him to take a shot from the edge of the box, beating the outstretched arm of Ben Foster in Watford's goal.
At the other end, Vicente Guaita denied Watford twice in the space of three minutes in the second half, first tipping a stinging long-range effort from Troy Deeney over the bar before keeping out Abdoulaye Doucoure's looping header.
Christian Benteke also came close as he attempted one of his trademark bicycle kicks, but despite making good contact with the ball he could only find the side netting.
Wolves' top-four hopes suffered a damaging blow after they were held to a dull 0-0 draw by Brighton.
Nuno Espirito Santo's side would have moved fourth with a two-goal victory over the Seagulls but were left frustrated.
They still climbed to fifth, having played a game more than Manchester United, but trail Chelsea by two points with the Blues also having a game in hand.
In an afternoon of few chances Solly March wasted the best when he shot over and battling Brighton will be happier with the point.
They now sit two points above the relegation zone but are still winless since December and remain precariously placed above the bottom three.
