A second half barrage from Morpeth Town saw Carlton go down 4-0 in Northumberland.
The Millers had been good value for their share of the spoils as the sides went in 0-0 at the break but once the Highwaymen opened the scoring on 64 minutes there was only going to be one outcome.
The home side began well with the ever-dangerous Liam Henderson testing Jack Steggles early on.
Steggles, making his 150th start for the Millers, dealt with that comfortably and also saved a drive from David Carson as Morpeth pushed forward without a great deal of cutting edge.
The same could be said for Carlton, who had just Aaron Opoku up front and rarely threatened the Highwaymen’s goal.
Shortly before half time Kieran Walker made an excellent block away from the goal line from another Henderson drive while Stokes chipped an effort just over the bar as the half time whistle blew.
Morpeth continued to press early in the second half with Steggles doing well to tip a Tom Potter drive over the bar.
Carlton looked reasonably settled keeping the home side at bay and Walker headed a Connor Bartlett free kick over the bar as the Millers looked to steal a goal.
But it was always a question of keeping the home side at bay and Morpeth finally breached the Carlton defence on 64 minutes. The Millers should have cleared a free kick from Ben Sayer. They failed to do so and when Sayer sent a second ball into the box Iulian Petrache fired home from close range.
The dam breached it was then only a question of how many the Highwaymen would score. They doubled their lead with 15 minutes to go when Sean Taylor slotted home following a through ball from Sayer.
Steggles made another save from Henderson before the striker was brought down by Walker, with Joe Walton converting from the spot.
With the game deep into added time Morpeth broke from a Carlton corner. A lovely passing move saw Walton feed Henderson and the striker grabbed the goal his performance deserved.
The final score was harsh on Carlton, who competed well but ultimately looked limited against an impressive Morpeth outfit.
The Millers players came over to give generous applause to the small band of travelling supporters who had made the longest away trip in the club’s history.
