Fishburn Park stunned previously unbeaten Teesside League title-chasers BEADS 3-2.
Keeper Kieran Noble was suspended and Mark Waterfield took up the gloves.
The deadlock was broken on 20 minutes as a superb Jake Faichney cross was met by Dan Brown six yards out, who planted his header across goal into the far corner.
Tempers then flared when a late challenge on Faichney resulted in the BEADS right-back receiving his marching orders with a red card.
Luke Storr’s free-kick was met by the impressive Mikey Kilpatrick, whose bullet header from close-range flew into the roof of the net.
BEADS were handed a lifeline on the hour as Jamie Lorrains’ challenge was deemed late and the ref pointed to the spot.
The penalty was duly converted to reduce the deficit and set up a tense finale.
Park seemed to panic and were pinned back and BEADS drew level when the hosts lost possession which resulted in the away side’s forward side-footing home after a cross into the box.
Fishburn responded well to the setback and regained the lead immediately.
Luke Storr picked the ball up on the edge of the box and curled an effort round the keeper and into the bottom corner to regain the lead in fine style with 10 minutes remaining.
Park could, and should, have put the game to bed, but James Organ-Simpson’s fine run ended up with him being tripped in the box and winning a penalty.
Brown stepped up and sent the keeper the wrong way, but pulled his effort wide.
The same man was then sent clear on goal, lifting the ball over the keeper but the ball hit the bar.
The damage was already done and Park had done enough to pick up a massive victory.
Coach Steve Mothersdale said: “This is just what we’ve needed after a tough few weeks.
“We were unlucky in the semi-final defeat against them and over two games we’ve been terrific.
“It just goes to show on our day we can beat anyone we have to find consistency.”
Man of the match was Kilpatrick, who had a great game.
Staithes Athletic moved further away from the foot of the table with a superb 2-0 win on the road at Thornaby Dubliners.
Neither side could break the deadlock in a tightly-contested first half on a bobbly playing surface, despite Athletic slightly edging possession.
The hosts had the perfect chance to take the lead after the break after winning a penalty, but Staithes custodian Matthew Sanderson saved the resulting spot-kick.
Staithes took full advantage of the penalty miss and broke clear shortly afterwards, Connor Hood went one-on-one with the keeper and calmly slipped the ball to the side of the keeper for Sam Calvert to make it 1-0.
The away side then doubled their lead and killed the game off in spectacular fashion after 75 minutes.
The Thornaby keeper took a free-kick way out of his box, which was cleared to Calvert just inside his own half and he duly smashed it on the bounce and it sailed into the net.
Left-winger Ryan Gibson was Staithes’ man of the match after an all-action performance on the flank.
Athletic’s win sees them move within three points of their hosts Dubliners, and just four points from derby rivals Fishburn Park.
Beckett League Second division leaders Lealholm dropped a couple of points when they visited Snainton Reserves on Saturday.
Snainton went ahead in the 27th minute and the interval score was 1-0 to Snainton.
The second half saw Lealholm re-group and move up a gear.
The equaliser arrived in the 61st minute when Nathan Gibson superbly volleyed in from 20 yards following a corner.
Nine minutes later Arran Leeman hit the crossbar for the visitors and five minutes from time Mark McCarthy shot over the bar with the goal at his mercy.
Snainton’s keeper Mike Webster saved superbly to prevent Callum Brown from scoring and the game finished all square.
Goalscorer Gibson was Lealholm’s star man.
