Durham's reward for sneaking fourth spot in the NatWest T20 Blast North Group, courtesy of Warwickshire's capitulation at Old Trafford, is an away trip to South Group table-toppers Gloucestershire who have the two leading run-scorers this year in Michael Klinger and Ian Cockbain.

Essex, who grabbed the final qualifying place in the South Group when their game against Glamorgan was abandoned after one innings due to rain, visit Nottinghamshire in the first of the quarter-finals on August 8.

The other two quarter-finals will see Northamptonshire, last year's losing finalists, host Middlesex and Yorkshire, who produced a late surge after a poor start to the group stage, will travel to Glamorgan.

Finals day will take place on August 20 at Edgbaston. Of this year's quarter-finalists only Northamptonshire and Middlesex are previous winners.
