Jamie Smith and Jordan Clark star with bat as Surrey pile on runs at Bristol

Jamie Smith’s maiden double century and a second first-class hundred from Jordan Clark gave early pacesetters Surrey a stranglehold on the LV= Insurance County Championship match with Gloucestershire in Bristol.

Unbeaten on 111 overnight, Smith had moved to 234 not out, from 430 balls with 34 fours, by the time his side were finally bowled out for 603 shortly after tea on day two.

Smith shared a stand of 244 – a record for Surrey’s eighth wicket – with Clark (137) but Gloucestershire responded impressively by posting 86 without loss.

Ben Sanderson blasted a gaping hole in the fragile Essex batting with four quickfire wickets to capitalise on Luke Procter’s marathon century and put Northamptonshire in total command at Chelmsford.

The pace bowler found the edges of a succession of bats – including Sir Alastair Cook’s – to help reduce Essex to 95 for eight at the close in reply to Northamptonshire’s 390.

Northamptonshire were able to add a further 157 runs to their overnight score, with Procter taking exactly six hours to compile his 113.

Keith Barker claimed his second five-wicket haul of the season as Hampshire and Lancashire continued their close-fought encounter.

The Lancashire-born Barker helped Hampshire secure a nominal six-run first-innings advantage after dismissing the visitors for 240, with Phil Salt and Tom Bailey’s half-centuries keeping their side well in the match, before Hampshire closed on 103 for three.

England Test hopefuls Dawid Malan and Harry Brook contributed superb centuries to a Yorkshire revival against Kent at Headingley.

Having been 227 for four, Kent were all out for 291 as Haris Rauf took a career-best five for 65. Yorkshire then recovered from 23 for three to close on 326 for five after Malan
