RYHOPE CW and Easington Colliery, battling it out for the championship, will meet in the final of the Sunderland Shipowners’ Cup.
But whereas the Colliers won their semi final tie with Cleator Moor Celtic at a canter, Ryhope needed extra time before seeing off a strong challenge by Kirkymoorside.
Ryan Rivis gave the Yorkshiremen the lead, which they held until John Butler levelled with 15 minutes remaining.
And in the first period of additional time, Ryhope celebrated as Martin Metcalfe hit the winner.
Robert Huntley fired Easington in front and within a minute, Michael Dickinson equalised for Cleator Moor Celtic.
From then on, though, the Colliers dominated and established a three-goal cushion courtesy of Adam McGuinness, James Huntley and Simon Todd, before Craig Scott scored a late goal for the visitors.
In the League, Houghton Town were unable to halt New Marske’s challenge for the title.
Daniel Price was their only scorer, with Ricky Phillips (pen), Andy Raw, Christian Kamara and Matthew Hamilton on target for New Marske, who remain third, behind Easington and Ryhope.
Ashbrooke Belford House stay sixth after losing to fourth-placed Darlington Cleveland Bridge, whose match-winners were Jack Johns, with a fortunate goal, and Christian Holiday.
Silksworth moved out of the bottom three with victory over basement side Prudhoe Town, who scored through Jake Strafford in the first minute.
It was not until early in the second period that David McKinlay equalised and his strike was quickly followed with goals by James Gillespie and Mark Robertson.
Chris Robertson was Boldon CA’s man-of-the-match in an emphatic win against Annfield Plain. He hit a superb hat-trick, with Shaun Reay adding to the woes of the visitors.
An only goal by Richie Farrell was sufficient for Stockton Town at Coxhoe Athletic and Redcar Athletic defeated Willington with strikes from Billy Millington and James Kesterton.
Ryan Hebb’s 84th-minute goal earned Wolviston a point at Hartlepool, who led thanks to Craig Hutchinson, while Jarrow and Windscale shared a goal-less draw at Perth Green.
