The home side, who are hoping to finish the season in the top four, put up a very good defensive performance on a blustery day and just edged a close low-scoring game to end Hull’s winning run.
Hull had the wind and a good amount of possession in the first half, but they failed to capitalise on this with a Humberstone penalty giving them a slender 3-0 lead.
The away side looked as though they would take this advantage into the second half but a good Sedgley Park try on the stroke of half-time by their winger Harrison converted by Glass gave the hosts a 7-3 interval lead.
The second period saw defences dominate and neither side made any clear cut openings. Sedgley Park eased their way to a 13-3 lead care of two second half penalties by their-off half Glass in the 48th and 54th minutes leaving Hull with much to do.
However, Sedgley Park were not to be denied and their defence held out to see the seal the victory.
