Leon Clarke bagged a brace as Coventry City beat Sheffield United 3-2 in their League One clash at Sixfields on Sunday.
Coventry went ahead early on with Clarke volleying home in the sixth minute after a cross from Blair Adams.
And the Sky Blues added a second in the 32nd minute when Carl Baker pulled the ball back from the byline on the right and Callum Wilson fired into the roof of the net from 12 yards out.
Coventry made it 3-0 in the 49th minute when Clarke netted his second after collecting the ball on the edge of the area and firing a low shot into the corner.
Sheffield United pulled one back in the 62nd minute when Lyle Taylor scored with a low 25-yard free-kick.
And a minute later City stopper Joe Murphy saved Ryan Flynn's shot from close range as United went close to adding a second.
Clarke almost scored his third goal in the 70th minute but his low strike was saved by George Long in the United goal.
The Blades made it 3-2 in the 80th minute when the unmarked Taylor headed in his second goal after a cross from the right from Ryan Hall.
But Coventry held on for the win to go 16th in League One, while Sheffield United remain bottom of the table.
A second-half goal from Ryan Lowe earned struggling Tranmere a surprise 1-0 win at fourth-placed Bradford - bringing the hosts' eight-match unbeaten run to an end.
In a game of few clear chances Lowe broke the deadlock in the 69th minute, beating keeper Jon McLaughlin with a low, angled shot into the far corner after Jake Kirby had flicked the ball into his path.
Tranmere were grateful to keeper Owain Fon Williams for a brilliant diving save to keep out substitute Caleb Folan's header two minutes from the end.
A largely uneventful first half was marred by a melee in the 27th minute involving both sets of players and both benches after Tranmere skipper Ian Goodison appeared to elbow winger Kyel Reid in front of the dug-out.
Lincolnshire referee Darren Drysdale booked Goodison after consulting with the fourth official much to the anger of Bradford manager Phil Parkinson, who clearly thought the defender ought to have been sent off.
