Hull City humiliated Carlisle, as the pre-season promotion favourites registered their first consecutive league wins of the season.
Hull's strike partnership of Gary Alexander and Lawrie Dudfield, who terrorised third division defences last season, both got on the scoresheet as Alexander hit a hat-trick and substitute Dudfield completed the scoring.
Hull manager Jan Molby said: "I'm really pleased that Gary Alexander got his first goals of the season, but this is only a turning point for us if we continue in this way.
"It's going to be hard work and we have a tough game up against Macclesfield on Tuesday."
Carlisle boss Roddy Collins had lost none of his sense of humour after the comprehensive defeat: "I thought we were brilliant and Hull got four lucky goals, they were four flukes! "I'm just very disappointed because Hull played well but we allowed them to play well."
It could have been a different story had Marc Nixon not spurned the first opening of the game. The Carlisle striker snapped at a shot on the turn, wide of the mark.
At the other end, former Carlisle midfielder Stuart Green forced Peter Keen into a low save, and moments later Hull were in front.
Ryan Williams floated a deflected cross from the left and as Keen dropped the ball, Alexander was on hand to notch the ball over the line.
Green, who has been the subject of a tense transfer speculation this week, cleverly carved out an opening for Alexander, but as his low drive rattled into the corner of the net, a belated offside flag cut short his celebrations.
The second half was completely one-sided and within four minutes of the restart Williams had crossed from the left for Alexander to head home his second of the contest.
Alexander then completed his hat-trick as he raced on to Green's throughball and slotted home from 12 yards.
With 12 minutes left sub Dudfield completed the scoring when he lost his marker to head home unmarked from six yards following Williams' corner
