County were made to pay for missed chances as they lost at home to promotion chasing Grimsby Town. The Hatters had a goal wrongly chalked off for offside whilst well on top in the first half, and although Alex Kenyon pulled a goal back after Town had scored two early second half goals, Andy Halls late red card for violent conduct put the seal on a bad day at Edgeley Park for Ian Bogie's team.
A scrappy first half, in which both teams showed their nerves for different reasons, was eventually taken control of by County as James McKeown was by far the busier of the two keepers.
The young keeper held efforts from Mark Cullen, Jon Macken, Lee Bullock, Kenyon and Halls before the biggest decision of the half went against the Hatters.
Neat play between Halls, Macken and Bullock created a chance for Danny Whitehead, Cullen smacking home the loose ball from a tight angle only to be wrongly ruled offside by an over eager linesman.
The busy McKeown made a breath taking save to deny the industrious Cullen, his header arrowing towards the top corner before the keeper tipped it wide, with Cullen striking the angle of post and bar minutes later.
The visitors created very little in exchange, Joe Colbeck blazing high and wide with their best opportunity.

The game swung the way of the visitors early in the second half as they made a flying start, Ross Hannah curling an effort, via a deflection, wide of Richard O'Donnell to give his side the lead.
Within minutes the lead had been doubled as Sam Hatton drilled home a free kick after Jordan Fagbola's foul on Andy Cook.
The Hatters won a lifeline as Danny Schofield's corner kick was kept alive by Whitehead who fed Kenyon on the edge of the box, the midfielder driving forward before unleashing an unstoppable shot into the corner to reduce the arrears.
The game began to become niggly with both sides receiving cautions for cheap fouls. Hatton for the visitors, Halls for County.
Kenyon almost grabbed a spectacular second, his effort clearing the bar whilst a volley by Cullen from Macken's knock flew just wide.
O'Donnell kept his side in it with a brilliant save from Colbeck after a quick break down the left. Whilst McKeown ensured victory for his side by tipping substitute Paul Marshall's effort over.
The final insult coming in the last of the four added minutes as Halls kicked out at Colbeck as several Town players piled on top of Jon Nolan who had challenged McKeown for a loose ball.
