Lee Bullock and Nathan Haslam's side needed a 14-goal swing to stand a chance of making the play-offs, a tall ask but, in truth, they barely looked like beating a determined Gainsborough side, despite Jacob Hazel's glancing header which levelled the scores for a short period of time.
After a strong performance at South Shields in the previous outing, Bullock and Haslam made on change with Marcus Giles, who was impressive off the bench at the 1st Cloud Arena, coming in for Jake Hackett, but he didn't have the same influence this time around.
It was Whitby who created the first clear-cut opening in the 7th minute, but Harry Green's effort was tame and comfortably held by Matt Yates in the Gainsborough goal.
Toby Gould the found the side-netting from a tight angle for Trinity, whilst Jovon Makama fired over the crossbar from close range.
Whitby attempted the take the lead with both Josh MacDonald and Hazel being denied by blocks and great goalkeeping. But it was Gainsborough who would take the lead in the 38th minute.
That was when, from almost nowhere, Makama opened the scoring, finishing smartly from distance beyond Shane Bland.
The second half took a while to get going, with Whitby's equaliser being the first moment of note in a game which very much had an end of season feel to it.
In the 73rd minute, Green's cross went all the way through into the net via the slightest of touches of Hazel's forehead which left Yates flat-footed as he was unable to read the flight of the ball given the number of bodies in the box.
But just after equalising, the Seasiders were back behind again when Alex Wollerton was on hand to tap into an empty net after Shane Bland's initial kick was too powerful for Adam Gell to control and Gainsborough exploited the space left in behind.
And while Whitby continued battling until the final whistle, other than a great chance for Hazel to score his 27th league goal of the season in stoppage time, they rarely looked like finding an equaliser and ended the season on something of a whimper.
