Oakhill – following last summer’s recruitment drive – have been the league’s standout team.
And they confirmed their status as the league’s best team by downing Leeds in their own backyard.
Last year’s title winners Leeds struck first via Adam Gillman as they fought to keep themselves in the hunt.
But Moses Seitler’s 65th minute free-kick would soon be followed by Gillman receiving his marching orders as the crunch clash turned on its head.
Osher Landes fired Oakhill into the lead before Seitler’s late penalty ensured the visitors would cross the Pennines with the trophy.
