Lancashire’s collapse began when George Balderson was leg before wicket to Potts for 16 but it really moved into top gear about half an hour later when Venkatesh Iyer played on to the Durham fast bowler and Tom Hartley immediately lost his off stump when not attempting a stroke.
Bailey prevented the hat-trick but nicked his second ball from Potts to Borthwick to leave yet another Lancashire innings in tatters on 195-8.
Hurst and Philip delayed Durham for a few overs but Borthwick’s bowlers were not to be denied. Hurst hooked Potts to long leg where Callum Parkinson took an excellent tumbling catch a few inches from the boundary rope.
The game ended when Potts was recalled and dismissed Phillip for 41. Last man Tom Aspinwall finished unbeaten on 26.
Durham take 24 points from the game, effectively ending any lingering fears of relegation, whereas Lancashire take one point, a return which keeps them in ninth place in Division One.
