Burnley are comfortably through to the next round of the FA Cup after a convincing 4-0 victory in the third-round replay at Turf Moor.
An Ian Moore brace and goals from Glen Little and Robbie Blake was just reward for an excellent display against a depleted Mariners side who barely mustered a single strike on goal all game.
Burnley, who were 2-0 up at Blundell Park before capitulating to draw 2-2 in the first game, were always in control and had it not been for Danny Coyne, who made a number of fine stops in the Grimsby goal, Burnley could have condemned Paul Groves' men to an even heavier defeat.
It was no surprise when Moore earned his side a well-deserved lead after 25 minutes. Burnley goalkeeper Nik Michopoulos unlocked a static Mariners defence with an accurate kick which found Moore who unleashed an unstoppable left-footed low drive past the helpless Coyne.
The second half began in similar vein to the first and Burnley resumed the upper hand.
But with new signing Michael Boulding unavailable because he registered for the Mariners after the two teams met in the competition first-time around, the Mariners struggled to create any clear-cut opportunities to trouble Michopoulos.
And with Grimsby's frailties up front being exposed, Burnley finally put the game beyond the Mariners when Little scored a well-crafted goal after 79 minutes. Blake waltzed past two Grimsby defenders before teeing up Little who made no mistake with a clinical right-footed strike.
Seven minutes later, Blake scored the goal his performance deserved when he converted a well-struck penalty after Dimitrios Papadopoulos had been hauled down by Steve Livingstone.
And the rout was completed at the death when Moore kept his cool in a one-on-one situation with Coyne to cement his side's place in the next round of the competition.
Burnley manager Stan Ternent called on Ian Moore to reproduce the goal-scoring
exploits which killed off Grimsby on a more regular basis after a comfortable
4-0 FA Cup third round replay win at Turf Moor tonight.
Two goals from Moore were the highlight of a convincing night's work as
Burnley eased through to the fourth round and booked themselves a trip to Second
Moore scored a glorious opener with a fine left-foot finish after he had
skipped beyond Steve Chettle but Burnley waited until the 78th minute to make
the tie safe with a solo effort from Glen Little.

Papadopoulos added Burnley a third before Moore broke free to complete the rout
in stoppage time.
Ternent said: 'We were off the pace for long spells and didn't look ourselves
at times but we still did enough and I thought the late goals showed our
superiority on the night.
'The main thing was to get through and although it was a little edgy at 1-0
we achieved what we set out to do.
'Ian Moore had a particularly good game and that's what I am looking for him
to produce on a regular basis.'
Grimsby player manager Paul Groves had no complaints and said: 'We had some
young players out there and it will be a good lesson for them, a lesson in
'We came to give it a go but we weren't good enough, Burnley were the better
side and deserved their win.
'We didn't create many chances and it was a bit too much for us but don't
take anything away from Burnley who played well and deserved their win.
'The First Division and our survival is the main thrust this season and we've
now got to make sure that we stay up.'
