Runaway leaders Hyde Park Knights were reined in for only the fourth time this season as Stainforth came from behind to secure a 1-1 draw.
But Stainforth are likely to be the most disappointed in the result as their hopes of securing the runner-up spot behind the Knights suffered a blow.
The Knights now need just a single point from their final two games to secure the U13 Division Two title after second-placed Harworth Colliery failed to take advantage of them dropping points.
Harworth were held to a 3-3 draw Edlington White Stars Red, who also have their eye on second spot.
Colliery remain second, two points ahead of Stainforth who have played a game more. Edlington sit a further point back, but like Harworth, they have two games to go.
If Sunday’s clash is anything to go by, Stainforth are not going to give up their pursuit of the runners-up tag without a fight.
They produced some excellent chances from the off against Hyde Park and were somewhat unfortunate not to find the net.
It did not look like being their day when Jada Letman-White put the Knights in front before the break.
But Stainforth would have the edge in a competitive second half as they pushed hard for the equaliser.
It eventually arrived when Rocco Rickaby struck the ball straight over the Knights keeper’s head.
The champions-elect did not take too kindly to being pegged back and surged forward in search of a late winner.
But they met a determined Stainforth keeper in Owen Edwards who produced some fine stops to secure his side a share of the spoils.
