|Bob Willis Trophy, Northamptonshire v Glamorgan|
|Venue: The County Ground, Northampton Dates: 22-25 August Start time: 11:00 BST|

Glamorgan coach Matthew Maynard is to make changes to the batting line-up at Northamptonshire after repeated problems in the first three Bob Willis Trophy games.
Joe Cooke looks likely to open in place of Charlie Hemphrey, with Callum Taylor set for a middle-order position.
Cooke would be making his first-team debut and Taylor a first-class debut.
Glamorgan scrambled a draw for the second consecutive week in their match against Gloucestershire.
"There will be a couple of changes in the batting," said Maynard.
"The opportunity could well present itself for the guys who performed in the intra-squad games [in July].".
Cooke, a 23-year-old left-hand batsman who can also bowl right-arm seam, played for Durham MCCU and Hertfordshire before joining Glamorgan in 2019.
Taylor, 22, was born in Newport but spent much of his youth in Australia before returning to Wales, playing four T20 matches in 2019.
"I do have an Aussie accent, I moved to Australia when I was quite young and played all my cricket there before I came back after my schooling to try to play for Glamorgan," he told BBC Sport Wales.
"Newport is definitely my cricketing home in Wales. After my school coaches Stephen Baker and Ross Wallace helped me massively over in Australia, the Knight brothers (Mike and Dave) at Newport got me over and helped me.
"It was a sense of coming home for a gap year, but there were a lot of Glamorgan people around Newport and it worked in my favour," added Taylor, whose middle name is Zinzan after the New Zealand rugby great Zinzan Brooke.
"It would mean the world if I get a debut. Me and my family are excited."
Glamorgan go to the County Ground for Saturday's start having drawn two and lost one of their fixtures in the Central Group of the Bob Willis Trophy.
That has left them out of contention for a place in the final with just two rounds to come of the truncated season.
Veteran seamer Michael Hogan, who has 599 first-class wickets, returns to the squad in place of Lukas Carey after being rested against Gloucestershire.
Northants are without captain Adam Rossington because of a finger injury, Ricardo Vasconcelos taking over, while once-capped England spinner Simon Kerrigan is included in the squad after nearly three years out of first-class cricket.
The match is due to go ahead at Northampton despite a spike of Covid-19 cases in the area.
