Dan Butler scored the winner as Newport County held off hosts Port Vale.
The Exiles led through Scot Bennett when he latched onto a loose ball to score past Vale goalkeeper Scott Brown.
Tom Pope equalised with a header from a corner, his 56th goal at Vale Park setting a new record at the ground.
But when Mark Harris' cross was missed by Padraig Amond - who was later forced off with a head injury - Newport left-back Butler was following up to find the bottom corner.
Vale pushed hard for an equaliser, having a strong appeal for handball waved away before Ricky Miller hit the post with a curling effort, but have now lost five of their last six games.
