Friends Life t20, Old Trafford
Lancashire 122-2 (14 overs) beat Durham 121 (19.2 overs) by eight wickets
Lancashire moved into a three-way tie on top of the North group in the FLt20 with an eight-wicket win over Durham.
Spinner Gary Keedy (4-25) and overseas paceman Yasir Arafat (3-21) were the main men as Durham scored just 121.
Only Gareth Breese's 33 off 15 balls gave the visitors anything like a total to defend after slumping to 65-5.
But Steven Croft (65no) and Tom Smith (40) made short work of it in a second-wicket stand worth 103 as Lancashire reached 122-2 with six overs to spare.
Nottinghamshire, Yorkshire and Lancashire all now have seven points from five games at the group's halfway stage, to stand three points clear of fourth-placed Durham.
Arafat's three scalps make him now the leading wicket-taker in the 10-year history of Twenty20 cricket in England, leaving him on 99, just one away from being the first to reach his century.
Playing for his fourth county, having had spells with Kent, Surrey and Sussex, he passed the tally of 97 wickets held by his countryman Azhar Mahmood.
After electing to bat, Durham did not use up their full allocation, their innings coming to an end two balls into their final over.
But Croft, who hit four fours and as many sixes in his 44-ball cameo, and Smith ensured that the home side would need even less time in the middle.
Smith fell to Borthwick as he tried to finish the match with a six, allowing Karl Brown to come in and hit the winning runs.
