Darlington Mowden Park and Blaydon both reached the second round of the Senior Knockout Cup on Saturday, while West Hartlepool, Tynedale and Westoe went out.
Injury time tries proved decisive as Blaydon went through 21-17 at Walsall and plucky Westoe went out 13-12 at Hull Ionians, robbing them of a trip to Liverpool St Helens.
Mowden are away to Waterloo in two weeks and were encouraged by the Blundellsands club's 50-15 home defeat by Esher in Division Two on Saturday.
Playing into a stiff wind at Bromsgrove, Mowden were level at 6-6 at half-time then overpowered their hosts to win 48-6, with winger Chris Mattison looking very sharp on his first appearance of the season.
With forward pressure starting to tell, they scored three converted tries in the first 15 minutes of the second half.
Centre Matt Howland scored following a line-out drive, then from a scrum in midfield Kevan Oliphant linked with Howland and Mattison rounded the full back to score.
Flanker Darren McKinnon and Mattison set up the next try for full back Kevin McCallum, and with Oliphant adding his third conversion to his two penalties Mowden began sending on the six replacements allowed in the cup.
Among them was prop Danny Brown, but he injured a knee so Ian Keeligan had to go back on.
Mowden had the audacity to run a penalty from under their own posts, with McKinnon breaking away to send Jonny Golightly on a 50-metre run before a return pass put McKinnon under the posts.
The spate of substitutions saw Golightly switch from centre to fly half, while Mark Bedworth took over the kicking and converted the next try by Howland.
Golightly scored the last try when scrum half Will Green ran wide and flicked the ball to him.
Blaydon will be at home to Fylde in the second round on September 29 after centre James Lofthouse scored and converted their injury time try at Walsall.
Despite facing the wind and conceding four penalties, all kicked by David Butler, Blaydon led 14-12 at half-time.
Vinny Bell, making his first senior start at centre, intercepted to score under the posts, then he broke through to put winger Barney Vorster over with Lofthouse converting from wide out.
Blaydon found themselves under pressure after the break and Walsall scored in the corner ten minutes from time to go 17-14 ahead.
But substitute Charlie Roe made the inroads which allowed Blaydon to snatch victory.
Injuries robbed West Hartlepool of five key players and they fielded two who were not fully fit in a 59-3 defeat at Dudley Kingswinford.
A penalty by full back Michael Walton provided West's only points and they were 56-3 down after 50 minutes before stepping up their resistance after Dudley sent on all their replacements.
Craig Stephenson kicked three downwind penalties to put Westoe 9-0 up at half-time, and he added another after Ionians scored a try.
Westoe led 12-8 until the hosts scored with the last move of the match, while Tynedale lost 17-9 at Nuneaton, who are Mowden's hosts in a league match on Saturday.
In the Intermediate Cup Durham City managed only three penalties from veteran Jon Bland in a 36-9 defeat at Hartlepool Rovers.
City led 3-0 until Rovers scored three tries in the last ten minutes of the first half through Mark Briggs, Graeme King and Martin Stacey.
Three more tries followed from Briggs, Darren Smith and Chris Nicholson, with Ian Drummond adding the conversions.
Former Middlesbrough fly half Ian Bircham scored 16 points, including a try, as Acklam overturned an 8-6 half-time deficit to win 26-8 at home to North Shields.
Redcar continued their good start with a 50-13 win at Hartlepool, but Whitby pulled out of their cup tie at Horden, who staged a friendly against Darlington and lost 69-7.
Former Hartlepool Rovers winger Ian Coulson marked his Darlington debut with two of the 11 tries but was upstaged by fellow winger Paul Beattie, who scored five.
David Glendenning scored two tries and kicked seven conversions, with Rob Stewart and Martin Howe also touching down.
In the Junior Knockout Cup Barnard Castle won 26-20 at home to Hartlepool BBOB, while Bishop Auckland came back from 8-5 down at half-time to beat Seaham 33-11.
David Dent set up a try for Ian Campbell, who added the conversion and was also on target after a penalty try plus touchdowns by Dent and Peter Sayer.
Stockton skipper Alan Brown marked his first appearance of the season with a hat-trick of tries, with Dave Turner adding the goal points, in an encouraging 23-7 win in the friendly at home to Driffield.
