Derbyshire finally mustered some resistance to take their Division One match against Durham at Chester-le-Street into a fourth day.
After subsiding for 113 in their first innings they were 49-5 in the second after being set a target of 472, but closed on 181-7.
Shivnarine Chanderpaul made 76 and put on 98 for the sixth wicket with wicketkeeper Tom Poynton, who remained unbeaten on 56 on his return to the side after being axed because of his lack of runs in the first four games.
Chanderpaul reached 50 off 73 balls then hit Scott Borthwick for three fours when the leg-spinner was finally introduced, only to be removed after conceding 34 in four overs.
Just as in the first innings it was Rushworth who persuaded Chanderpaul to feel for a ball just wide of off stump, which he edged to Phil Mustard.
Chris Rushworth, the man nominated to stand down if Graham Onions became available, followed his 6-64 in the first innings by taking three more wickets.
In the morning Durham opener Keaton Jennings followed his 93 in the first innings by completing his maiden championship century.
Resuming on 65, he made his way carefully towards the milestone with a series of singles and reached his hundred off 247 balls.
He was on 122 at lunch, when Durham led by 446 on 306-7, but added only one before being run out.
Mark Wood fell lbw on the back foot to give occasional off-spinner Dan Redfern career-best figures of 3-33 and Durham declared on 331-9.
