Sussex were left reeling after brilliant performances from Chris Rushworth and Cameron Steel led Durham's fightback on day two of their Specsavers County Championship division two clash at Emirates Riverside.
After being bowled out for 103, Rushworth dragged the home side back into the contest by claiming figures of 8-51.
Sussex failed to capitalise on their solid bowling performance, after Ollie Robinson notched his third five-wicket haul on the bounce, boasting only a lead of 19 over the hosts.
Steel and Alex Lees formed a solid partnership at the top of the innings in response.
The 22-year-old held his composure to reach three figures for the first time this term, becoming his county's fifth centurion of the season. At the close of play the hosts held a 201-run advantage (220-4) over Sussex with six wickets remaining in their second innings.
