Durham went from the ridiculous to the sublime on the third afternoon of their home match against Glamorgan, losing five wickets for six runs before the last-wicket pair put on 68.
Chris Rushworth made 38 and Barry McCarthy an unbeaten 30 as they gained the fifth batting point with two balls to spare.
Durham were all out for 402, a lead of 107, when Rushworth chipped Michael Hogan to mid-on.
After resuming on 281 for four when play began at 1.10 following thundery storms, Paul Collingwood and Ryan Pringle advanced the score to 328 in the first 12 overs.
It appeared to be plain sailing when Pringle hit Hogan for three fours in four balls, but he fell lbw to the next to spark the rot.
Hogan made way for left-armer Graham Wagg, who had Paul Coughlin caught behind first ball. Then Collingwood departed for 92 when he was unable to evade a a steeply-bouncing ball which Marchant de Lange angled into him. It lobbed off a glove to gully, where Aneurin Donald moved smartly forward to hold a low catch.
An in-swinger from Wagg had Stuart Poynter lbw for four then Matty Potts failed to register before de Lange banged one in and had the youngster caught at short leg.
Durham still needed 16 for the fourth batting point when Rushworth joined McCarthy. But they were relatively untroubled once de Lange rested after a 12-over spell, in which his two for 30 took his overall figures to five for 95.
