Pringle dash not enough for Durham
Lancashire 133 for 6 (Brown 66) beat Durham 132 for 7 (McLoed 45, Khan 3-21) by one run
Ryan Pringe made a late charge but fell one short as Lancashire secured the narrowest of victories, holding on to defeat Durham by a single run at Chester-le-Street.
Pringle took strike with 21 needed in 10 balls and found the boundary twice to leave four needed from the final delivery, but he could only manage two as Kabir Ali escaped having had 15 to defend in the final over.
Durham looked set to reach the target with ease before three wickets fell for two runs in the middle of the order to set up a tense finale.
Durham lost Mark Stoneman in the third over but Calum MacLeod's 45 from 34 balls looked to have put the hosts in control. But three wickets fell for just two runs when Paul Collingwood was quickly followed back to the pavilion by MacLeod and Gareth Breese as Durham were left struggling on 100 for 6 with 23 balls remaining - 34 short of their target.
When Junaid Khan bowled Gordon Muchall in the 19th over, Durham needed more than two runs a ball to win with only three wickets in hand. That left Michael Richardson and Pringle at the crease, with 15 needed from the final over for victory.
Richardson struck three from the first ball by Kabir Ali, with Pringle blasting a boundary with the next and two runs and a single from the subsequent balls. A single from the fifth ball of the over left Durham needing a boundary to win, but Pringle could only find two.
Karl Brown top-scored for Lancashire with 61 from 51 balls before he was removed by Chris Rushworth as the visitors finished on 133 for 6 from their allotted overs. Brown powered to the half-century mark in 44 balls with a flurry of boundaries for Lancashire in a bright performance with the bat before he was caught at long-off by Muchall.
Jordan Clark was the next highest scorer for the visitors with 27 as Durham shared the wickets, with only Pringle not claiming a scalp as Lancashire stuttered to a defendable target from their 20 overs.
Alex Davies was caught behind off Usman Arshad, with Tom Smith, Paul Horton and Steven Croft all dismissed by the 12th over as Lancashire slumped to 54 for 4. Brown and Clark then added some much-needed stability and firepower to move their side on to 127 before the former's dismissal.
Andrea Agathangelou and Arron Lilley were unable to add to the score as Lancashire's innings drew to a close.
