Durham Jets (90-4, Collingwood 34, Coughlin 38*) win by six wickets over Leicestershire Foxes (88-2, Ronchi 63*)
Durham completed a stunning first win of the season at the expense of Leicestershire in a match shortened by rain to seven overs a side at the Fischer County Ground.
The visitors quickly lost two wickets in their chase of 89, but captain Paul Coughlin (38 not out off 18 balls) and the experienced Paul Collingwood (34 of 18) added 76 runs for the third wicket, hit from just 33 balls.
A impressive innings of 63 not out from 21 balls from opener Luke Ronchi should have put the Foxes in an impregnable position after acting captain Colin Ackermann won the toss and chose to bat first on a good pitch.
The New Zealander hit 10 fours and two sixes, going to his 50 off just 16 deliveries, equalling the third fastest half-century in domestic T20 cricket, behind only Marcus Trescothick (13 deliveries) for Somerset and Gerard Brophy (14) for Yorkshire.
But the sixth over of the Foxes innings, bowled by young seamer Barry McCarthy, yielded only one run as Tom Wells swung and missed, opening the door for the visitors.
