Durham wrapped up victory after lunch on Day 4 at Chester-le-Street after some brave Sussex resistance finally came to an end.
Tom Haines fell to Oliver Gibson for the only wicket in the morning session after the visitors took a more positive approach to playing the hosts’ attack in good batting conditions, Haines and James Coles adding a 50 partnership in quick time.
However, after lunch Coles fell to Ben Raine LBW before Matthew Potts removed Charlie Tear with a short ball in the following over, Liam Trevaskis taking a smart catch at short mid-wicket.
Raine bowled Jack Carson to complete his fifer and Potts had Faheem Ashraf caught off a short ball to give Durham the win, with Henry Crocombe was unable to bat after damaging his shoulder in the field on the first day.
Sussex remain 7th in the table with one game to go next week at The 1st Central County Ground, beginning on Monday 26th September.
