Daley's injury sparked Durham's collapse

Gordon Muchall and Andy Pratt appeared to have settled things down for Durham taking them on to 211 for four but Derbyshire debutant Syed Mohammad Ali removed them both to send shivers through the Durham camp.

Cork then returned to pick up Bridge for one but Durham still seemed well set as Neil Killeen and Mark Davies nursed them to within three runs of the target.

Ever the man for the big occasion, Cork stirred himself once more dismissing Killeen but with Daley returning to the crease Durham were still favourites.

However, Daley was unable to get the strike, leaving Cork with a full over at Davies.

With his first-ball he had Davies caught by Luke Sutton and with his second he repeated the trick to new man Steve Harmison, picking up his fifth wicket in capping a remarkable win.

Durham had been frustrated in the morning by a last-wicket partnership of 61 between Kevin Dean and Lian Wharton.

Dean, whose previous first-class best was just 27, completed his maiden half-century before finally being dismissed by Collingwood with the score on 229.
