Colwyn Bay are now 34 points from safety with five matches left to save themselves in the Premier League after Saturday’s loss at high-riding Northern.
The Merseyside hosts won the toss and batted, piling up 254-5 declared off 49 overs, prolific left-hander Tyler McGladdery scoring 113 and Chris Laker 63.

In reply, the visitors were all out for 168, Dan Russell 30, Tomas Sephton a remarkable 8-48 for the 25-5 points winners from Crosby.
After electing to bat, Prestatyn were blown away for just 62 at Paton Field and Caldy eased to 67-2 in just 15.1 overs to seal an eight-wicket success, Benjamin Hughes 2-28 for the Welsh side.
Second-place Northop Hall kept their promotion bid bubbling with an eight-wicket triumph which gives them a 40-point buffer to the next club below.
Opting to field, the hosts sent Fleetwood packing for just 72, Paul Jenkins collecting his eighth five-wicket haul of the season, a return of 5-20 off 14 overs putting him on 72 victims in 2025.
Carwyn Johnson bagged 3-45 and James Hurlin 2-3 off 5.3.
Hall reached a winning 72-2 off 18.1 overs, Matthew Jones 28 not out, sealing a 20-1 points verdict.
Bay seconds dropped out of the promotion slots after they could not quite finish off visitors Highfield at Penrhyn Avenue.

Liam Evans-Ford snapped up 4-38, Robbie Edwards 3-41 and Matteo Evans-Ford 2-49 as Northop Hall seconds dismissed the hosts for 168, but in reply the Flintshire side had to see the game out for a draw, ending on 135-8, opener Hollie Sigsworth 32, Adam Jenkins 30 not out.
Ben Williams took 2-59 for Prestatyn seconds, whose attack came in for some hammer as visitors Sutton amassed 201-3 declared off 39 overs, then the hosts were blasted out for a paltry 60, Niladri Dutta a defiant 34, Liam Dodd 7-25 for the Merseyside team.
