Port Vale were dumped out of the Carabao Cup after losing 4-1 at Leeds United.
Samuel Saiz put the home side ahead early on, before Michael Tonge equalised against his former club.
Saiz then went on to complete his hat-trick with two goals in as many minutes either side of the hour mark.
Caleb Ekuban then completed the scoring seven minutes from time.
Vale defender Gavin Gunning was then sent off in the 87th minute for two bookable offences.
The Valiants are back in action on Saturday when they play their first home game of the season against Wycombe who are managed by former Vale favourite Gareth Ainsworth.
