Grimsby Town boss Nicky Law was delighted to secure his first win since taking over.
He agreed that the result was the all important thing and added that Grimsby had done what they had to do early on and by scoring twice had made it difficult for a Wednesday side who went down to ten men before half time.
And of the second half he said: "We got pegged back after the interval and were a bit nervy. But any problems we had we caused ourselves and another two wins should be enough to keep us safe." Laws was delighted that Grimsby's win, plus other results, moved them out of the bottom four and up two places but added that although other results could help it was what the Mariners themselves that really counted.
Wednesday boss Chris Turner, meanwhile, was concerned about his side's lack of discipline with another red card which effectively ended the Owls' hopes of getting back into the game.
Grimsby had the best possible start when in the fifth minute, a defensive mix up between keeper Kevin Pressman and defender Brian Barry-Murphy let in striker Darren Mansaram to put Grimsby ahead.
And although Wednesday threatened briefly to come back their defensive failings were shown up again when former Wednesday player Tony Crane was left unmarked on 32 minutes to loop a header over Pressman from an Iain Anderson free kick.
As if Wednesday were not up against it enough already, they lost striker Guylain Ndumbu-Nsungu for violent conduct.
This left Wednesday short up front and although a double substitution midway through the second half gave Wednesday a second striker, they could still not muster a shot on Alan Fettis's goal.
In fact it was Grismby who had the best chance of the half when leading scorer Phil Jevons headed wide from a great chance.
