Durham 573 for 9 (Bedingham 279, Ackermann 186, Wells 4-69) beat Lancashire 228 and 282 (Hurst 67, Bohannon 56, Potts 9-68) by an innings and 63 runs

At one stage of his devastating spell from the Lumley End, Potts was on a hat-trick but he had to settle for three wickets in four balls when Tom Bailey nicked his second delivery to first slip Scott Borthwick. The Durham spearhead finished his first spell on this final morning with figures of 10-1-30-5 and ended the game when he had Anderson Phillip leg before wicket to complete a match return of 12 for 126.

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 and deepens their anxieties that they will be playing in the second tier next April.

Lancashire’s collapse began with the ninth ball of the morning 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 for eight.

Hurst and Anderson Philip delayed Durham for a few overs but Borthwick’s bowlers were not to be denied. Having made a fine 67 off 125 balls, Hurst hooked Potts to long leg where Callum Parkinson took an excellent tumbling catch a few inches from the boundary rope.

After an entertaining last-wicket stand of 61 in 12 overs between Anderson Philip and Tom Aspinwall, the game ended when Potts was recalled and dismissed Phillip for 41. Aspinwall finished unbeaten on 26.

The bad news for Durham supporters ahead of their final two Championship games is that Potts will now join England’s squad for the one-day internationals and will not be available to the county for the rest of the season.
