Warwickshire piled up the second-highest total in their history to put Durham under serious pressure in their Vitality County Championship Division One tussle at Edgbaston. The home side, led by Alex Davies’ maiden double-century, amassed a mammoth 698 for three declared to leave Durham needing 549 even to avoid the follow on. The visitors closed the second day on 178 for three with Alex Lees (94 not out, 171 balls) leading the resistance but with a huge amount of work still to do to dig his side out of trouble.
