In the truth, the goal was out of keeping with a game in which both sides worked hard but could not produce much quality in the final third. A draw might have been a fairer result but it has to be acknowledged that Snaith's goal was worthy of winning any match.
Glassboys manager Gary Hackett was forced into making changes by the absence of three of the back four that had kept clean sheets against Skelmersdale and Kin's Lynn. Exodus Geohaghon, Keiran Morris and Kyle Haynes were all missing, so Kristian Ramsey-Dickson partnered Leon Broadhurst in central defence, with Brian Smikle filling the void at right back.
Stourbridge had the first half-chance, with Kayelden Brown opting to cross from the left when he perhaps would have been better trying his luck, and at the other end Ramsey-Dickson was robbed on the dead-ball line and from the ensuing cross James Brown hit the crossbar with a shot that he failed to keep down enough.
Whitby controlled the game for long spells in terms of territory and possession but Dean Coleman in the Stourbridge goal was untroubled by a couple of shots that sailed wide, although he was called into action on 23 minutes to save a low shot from Snaith, with Brown only able to put the follo-up wide off the outside of the post.
George Bowerman managed to get a shot on target on 29 minutes, but Kevin Burgess was on hand to clear with keeper Shane Bland beaten, and Stourbridge had their best chance of the half on 34 minutes when Drew Canavan's pass put Will Richards clear. However, Richards opted to cut back inside onto his right foot inside of shooting first time, and Bland was then equal to his effort with a good save.
The second half was generally more even than the first but still neither side could make the most of what openings they created. Big central defender Richard Pell shot well over for Whitby from an early corner and Stourbridge forced a number of corners from which shots from Richard, Broadhurst and Ramsey-Dickson were all blocked.
Coleman was forced into a fine diving save low down by his post on 73 minutes, whilst a snap-shot from Brown was comfortably held by Bland after 83 minutes.
It seemed, though, that stalemate would be the order of the day until three minutes into stoppage time. Richards, who had just been named as the Glassboys Man of the Match by the sponsors, missed a tackle on Snaith in his own half and the Whitby man curled a sumptuous shot from 25 yards out of the reach of Coleman.
The defeat means that Stourbridge drop a place to 10th in the Ev-Stik League Premier Division table.
