Jon McCarthy's second goal for Carlisle ended their run of six matches without a win and lifted them out of the Third Division relegation zone with a fine 1-0 victory over Southend.
The Northern Ireland international struck after 32 minutes when new signing Adam Rundle squared the ball into the penalty area and McCarthy blasted a shot from six yards that left Southend goalkeeper Danny Gay standing.
Carlisle rode their luck soon after when Mark Rawle's shot looked goalbound but hit the underside of the crossbar and bounced down into the arms of relieved goalkeeper Matty Glennon.
The home side could have doubled their advantage two minutes into the second half when Southend defender Phil Whelan hit Adam Rundle's cross against his own post, with McCarthy hitting the rebound wide.
Rundle struck the post later on with a left-foot shot and McCarthy was once again denied when his shot from the rebound was cleared off the line by Leon Cort.
Gay did well to parry a shot from Craig Farrell late on as the Cumbrians went on to claim all three points.
