Durham 215 for 5 (Cook 67, Richardson 51, Collingwood 65*) beat Leicestershire 211 (Chappell 59*, Weighell 4-34, Collingwood 3-42) by five wickets
Paul Collingwood hurried Durham to a five-wicket Royal London Cup win against Leicestershire at the South Northumberland club ground in Gosforth.
After taking 3 for 42 in dismissing the visitors for 211 with one ball unused, Collingwood went in at 122 for 3 and remained unbeaten on 65.
Leicestershire were brought swiftly back to earth after their 103-run win against Warwickshire, slumping to 13 for 4 after losing an important toss.
Fresh from his 153, Mark Pettini edged Chris Rushworth's second ball of the match behind and although the pitch appeared to have good carry, Cameron Delport and Aadil Ali both lobbed up easy catches from mistimed drives.
They provided James Weighell with the first two of his four wickets, the third coming when Ned Eckersley also surrendered by hooking straight to long leg.
Mark Cosgrove was beginning to look dangerous when, on 21, his attempted pull off Paul Coughlin flew off the top edge over the wicketkeeper for six. But, on 37, he clipped Collingwood straight to deep square leg.
At 68 for 6, Zak Chappell went in and remained unbeaten in compiling his maiden one-day half-century. He reached 50 with a fierce pull wide of long-on off a slower ball by Weighell and had eight other boundaries in his 59 off 82 balls.
Lewis Hill was the second-highest scorer with 44 before he clipped Collingwood to mid-wicket and was brilliantly caught by Keaton Jennings, diving to his left. Dieter Klein helped Chappell add 73 in 17 overs for the ninth wicket before he heaved across the line in the 49th over and was bowled by Weighell for 26.
When Durham replied, left-armer Klein surprised Jennings with a full toss which had the Durham captain lbw for 12. But Michael Richardson was soon in full flow as two cuts off Gavin Griffiths flew to the boundary.
Richardson reached 50 off 65 balls but then went back for a second run to third man and found himself at the same end as Stephen Cook with the throw heading for the other end.
Cook was bowled for when trying to run Tom Wells to third man then Cameron Steel fell lbw to a yorker in the same over with 33 still needed. But Collingwood hit two sixes and six fours in his 45-ball half-century and quickly finished the job.
