The result sees Newport 13th in the League Two table, seven points off the playoff places – although at half-time with results going their way they were just three points off with two games in hand at one stage.
Manager Justin Edinburgh made three changes from the side that lost 2-1 at Mansfield on Saturday. Ian McLoughlin made his debut in goals after signing earlier in the day following Elliott Parish’s return to parent club Bristol City.
Harry Worley and Max Porter were also brought in to replace Byron Anthony and Ryan Burge respectively.
The red card really was the turning point as County were well on top and leading until that point
The Exiles started brightly and took a 13-minute lead when Naylor fired home after a corner fell to him in the box. McLoughlin was then on hand to deny Ellison, and the Morecambe striker had the ball in the net soon after but was correctly ruled offside.
County deserved their half-time lead but fell to pieces in the second period following Naylor’s red card for bringing down Ellison when he was clean through on goal.
The defender will be happy to see the back of Morecambe after scoring two own-goals and conceding a penalty when the sides last met, and conceding another penalty tonight with a red card to follow.
Devitt sent McLoughlin the wrong way from the spot and the home side took the lead shortly after when Ellison fired home. Redshaw came off the bench and scored seconds after coming on with a header from a free-kick, his first touch of the game.
And he scored again to make it 4-1 as Morecambe made their numerical advantage count. Chris Zebroski twice came close late on but his efforts were just wide of the goal.
The red card really was the turning point as County were well on top and leading until that point. Exeter next up for Edinburgh's men at Rodney Parade on Sunday.
