Duckens Nazon and Peter Vincenti hit second half goals as Coventry defeated Carlisle 2-0.
The Haitian emphatically fired home three minutes after the restart before Vincenti made the game safe with 10 minutes to go.
It was a much improved second half for City after they had been effectively stifled during a tight first half.
United started brightly with Jamie Devitt forcing Lee Burge into a superb reaction save in the 11th minute.
Liam Kelly blazed over while stretching following a flowing Coventry move on 20 minutes.
Shamal George did brilliantly to save Stuart Beavon's powerful low shot on 37 minutes.
But there was nothing he could do to stop Nazon after he latched on to Kelly's perfect pass to put the home side ahead.
George saved Jodi Jones' shot with his feet on the hour, before Danny Grainger cleared a Jones shot off his own line eight minutes later.
But it was game over when Vincenti's mis-hit volley beat George to wrap up back-to-back wins for the Sky Blues.
