Surrey v Sussex, Somerset v Yorkshire, and more: county cricket, day two – live

Surrey stepped up security at the Oval following the knife attack at Golders Green as off-field decisions took the headlines on day one of round five of the County Championship.

In a statement, the club said: “Surrey are in communication with the Met police and will adjust our own security measures in line with the increased threat level. We want to ensure that all staff, spectators and players feel safe and secure.”

On the pitch, which last week was a gentle duvet, Sussex were reduced to 92 for seven, thanks largely to Jordan Clark (five for 68). But the tail wagged, and wagged some more, as Fynn Hudson-Prentice thrashed 53 before Jack Carson and Ollie Robinson hit boundary-laden hundreds.

Robinson, the visiting captain, reached three figures with a swipe for six and then declared. Surrey, who were without Gus Atkinson, rested by England, walked off in great frustration. Jamie Smith kept wicket after Ben Foakes was ruled out of the match, having injured himself bowling during the final afternoon against Essex.

The Kent captain, Daniel Bell-Drummond, collected a Rolls-Royce of a century at Canterbury, after Derbyshire chose to field. Zak Crawley stroked a boundary-filled 44. Kent, who lie bottom of Division Two, had earlier this week taken the unusual decision to switch comments off the club’s social media accounts as a “duty of care”.

It was a gripping day at Taunton, where an enthusiastic crowd were treated to 45 minutes of Jonny Bairstow and Joe Root pistoning Somerset’s attack. But after lunch Lewis Gregory zipped out Root, and Craig Overton, who had dropped Bairstow at slip, induced an inside edge. Suddenly, Yorkshire lost seven for 38 and were all out for 162. Then Josh Thomas, 21, made a bravura first Championship century, taking Somerset into the lead with a six.

Ben Stokes, recovering from a broken cheekbone, was spotted in the Durham nets at Lord’s. Over on the main square, Sam Robson (87) and Ryan Higgins (57) guided Middlesex towards 300. At the County Ground, Gareth Roderick hit 164 not out – Worcestershire’s first century of the season – to put pressure on Northamptonshire.

A careful maiden Championship century for Saca graduate Zain ul Hassan, and 158 for Kiran Carlson, left Glamorgan in a dominant position against Hampshire at Southampton. At Grace Road, Nottinghamshire flourished after being put in by – Ben Slater’s 178 backed up by Ben Duckett’s third successive half century.
