Wearmouth CW succumbed to only their second defeat of the season, losing out in an end to end Division One derby against Grindon Broadway.
Both sides missed good first-half chances, Wearmouth starting very strongly only to find the visiting defence in resilient mood.
Grindon made the better start to the second half and were rewarded when Paul Griffiths made the breakthrough after 55 minutes.
Five minutes later, James Armstrong made it 2-0 to complete the scoring and help Grindon consolidate fifth place.
Easington CIU succumbed 4-2 to visitors Heaton Stannington, who are now three points clear of Wearmouth at the top.
They started brightly and Norman Hird hit the post, but a defensive error let Heaton take the lead. The visitors had a man sent off before CIU rallied, with Greg Holland denied an equaliser by a wonder save.
Heaton doubled their lead only for Easington to hit straight back, Antony Ward heading in a Tigger Lyons cross at the back post. The fightback was shortlived though as two more defensive blunders allowed Heaton to take a 4-1 lead, though Hird hit a late consolation.
David Banks starred for CIU.
Washington Sandpiper are fourth after beating Milbourne Arms 2-0. Bottom club Dubmire lost 3-0 to North Ormesby Vets.
Rolls-Royce enjoyed a 6-3 victory in an entertaining Third Division clash with Boldon Colliery Tavern.
Rolls quickly went 2-0 up with goals from Gary Anderson and Davy White, but Boldon responded before White’s second restored the two-goal advantage.
Boldon showed great character to fight back to 3-3 by the interval, but Rolls took command in the second period, with a delightful chip from Wayne Browell putting them 4-3 up. Gary Barker, not to be outdone, scored a 35-yarder which had the keeper beaten all day, then White completed his hat-trick for 6-3.
The Philadelphia shared the spoils with Washington JFC Biddick Inn in a six-goal thriller.
Biddick grabbed a fifth-minute lead when a beautifully flighted free-kick gave Phili’s defence no chance and the ball was stroked into the net.
Biddick doubled their lead, finishing off a good move at the far post, in just the 10th minute. The Philadelphia rallied and skipper Neil Machin cut inside from the left and, after some good interplay, pulled one back, calmly steering the ball into the net.
They equalised when Paul Russell was felled by a mistimed tackle and got up to convert the penalty into the bottom corner.
Biddick were back in front with a third goal on the counter-attack on 70 minutes, but Phili went all out on attack and the gamble paid off when Russell beat his marker on the edge of the area and drove his shot across the keeper and into the bottom corner.
John Hall (2) and Gary Fox struck for Biddick.
Oddies secured a 2-1 win over Hartlepool Stag & Monkey, storming to victory on the back of a quickfire start and two goals inside the first 20 minutes, then strong defensive resilience as Stag hit back.
Blue House stayed a point behind leaders Wingate Cons when they beat Hedworthfield Red Hackle 4-1, while lowly Willow Pond put up a brave fight in their 1-0 loss to Wingate and Houghton Cricket secured an excellent 4-1 success at Sedgefield Black Lion.
Ivy Legends climbed to third place in Division Four thanks to an excellent 3-1 victory over Pelton Newfield.
The win, though, was marred by an injury to long-serving full-back Ronnie Page, who suffered a career ending knee injury after an innocuous challenge late in the game.
Ron successfully underwent a major operation the following day and is recovering at home. Earlier, a brace from Michael Cleugh and an own goal saw Ivy recover from 1-0 down to deservedly claim the three points.
Colonel Prior bagged only their second win, pipping Sunderland neighbours Oddfellows Arms 3-2, while Wearmouth Old Boys were beaten 5-2 at Stanley Ball Alley.

Hylton CW regained winning ways in Division Two, mauling Cobblers Hall 8-1, while Mill View SC were walloped 6-1 by Blakelaw SC, second-top Seaham drew 1-1 with leaders Thornley Celtic and Horden Sportsmans were beaten 4-0 by Durham Stonebridge.
