Goals from Gary Roberts and Doug Loft were not enough as Vale went out of the Carling Cup after a first round defeat to Huddersfield Town.
Micky Adams made a number of changes to the side with Chris Martin starting in goal, Ryan Burge making his full debut in midfield and Sean Rigg moving upfront to replace the injured Marc Richards.
Vale took the lead when Gary Roberts struck home, but the visitors took a one goal advantage into the break thanks to Lee Novak’s brace.
The visitors added further goals from Hunt and Gary Roberts, before Doug Loft scored a late consolation penalty.
After the game, Micky Adams told the official Port Vale website: “We were beaten by the better side, but having said that, there were spells in the game when have had good chances.
“I thought our football and shape was good at times, but they have match winners.
“Last season we had problems scoring goals. This season it looks like we have plenty of goals in us, but we are not defending well as a unit.”
