BIG John McCombe scored a first career hat trick as the Reserves scored a crushing win at Meadow Lane.
The no-nonsense central defender nodded Town into the lead on 39 minutes and, after Luke Caulfield had added another, he gave Town complete control with a three-goal lead just four minutes into the second half.
Anthony Lloyd rubbed salt into the County wounds with a superb fourth strike five minutes from time, but the day belonged to McCombe, who was on hand at the back post to knock in Lee Fowler's searching free-kick in the third minute of stoppage time.
It was a special moment for the 19-year-old, who has impressed in his two starts for the senior side this season and who opened his first-team goal account only 10 days ago against Blackpool in the LDV Vans Trophy.
Manager Peter Jackson - who helped roar Town into more purposeful action from the touchline late in the first half - watched McCombe's heroics against a County side including loan man Chris O'Grady from Leicester, and he's almost certain to have him on the bench against Stockport in the FA Cup.
If Town go into the first round tie with a shortage of strikers, and John McAliskey missed yesterday's clash because of a groin niggle, then McCombe might just fit the bill as an emergency.
While his first goal was a gift - he headed home from no more than a yard after Will Thacker had blocked Fowler's inswinging corner on the line - his second was a cracker.
County struggled to clear their lines as Town forced a couple of corners at the start of the second half and, when one partial clearance fell to McCombe about 20 yards out, he unleashed a searing right-foot volley which keeper Steve Mildenhall couldn't get near.
The hat trick goal was another tap-in and, in a way, it summed up how easy it had been for Town, who took themselves to 12 points in fourth place in the table behind leaders Scunthorpe, Lincoln and Doncaster.
It was encouraging to see Caulfield on the scoresheet because he's not been getting a regular match due to the switch to Under 18 in the FA Academy Premier League, and after a couple of promising runs he slotted his goal nicely from a nod through by Adnan Ahmed in first half added time.
Mark Sheridan was another to get a rare start, and he was available for the pass when Lloyd, about 25-yards out, scored a curling right footer in expert style. By then, Tom Clarke and Gavin Huxall - stars with the Juniors the night before - were on as subs.
Town - Senior, Hardy, Lloyd, Fowler, McCombe, Brown, Caulfield (Huxall 80), Sheridan, Collins (T Clarke 75), Ahmed, Young. Other subs: Giles, Shaw, Evans.
