Surrey slide into further trouble
Watch highlights of Durham facing Surrey
Surrey appear likely to remain rooted to the foot of Division One in the LV= County Championship after Durham took control of their match at the Emirates Durham ICG despite Chris Tremlett taking 8-96.
The seamer’s career-best figures represented an impressive return, but also reflected the lack of support from Surrey’s other bowlers on a pitch that Durham's new generation proceeded to exploit.
In the absence of three frontline seamers, the youngsters reduced Surrey to in reply to 421 before bad light halted play at tea-time.
Left-armer Jamie Harrison and 20-year-old debutant Usman Arshad took two wickets each, while Mark Wood bowled Hashim Amla for 14 with his first ball.
Wood came on for the 13th over and seemed to surprise Amla with his pace. The South African maestro played back and the ball skidded through his defence to hit off and middle.
Bradford-born Arshad, a Durham academy product, struck with his eighth and 12th balls in first-class cricket. Zander de Bruyn played back against the brisk medium-pacer and chopped the ball into his stumps, then Gary Wilson edged to Phil Mustard.
In eclipsing his previous best of 6-44, Tremlett also recorded the fifth-best figures in 18 seasons of first-class cricket at the Riverside ground. They were also the third best in the country this season, behind Steve Magoffin's 8-20 for Sussex against Somerset and Alan Richardson's 8-37 for Worcestershire against Gloucestershire.
Having taken all five wickets to fall on the first day, 35 minutes had elapsed on the second before Tremlett had nightwatchman Harrison caught at second slip.
He rested after one more over, at the same time as umpire Mark Benson left the field after receiving a call regarding a family emergency. He was replaced by local league umpire Philip Raine, who stood at square-leg while Michael Gough officiated at both ends until ECB reserve list umpire Paul Baldwin arrived in mid-afternoon.
Tremlett's chances of taking all 10 were dashed when, with two needed for Durham’s fourth batting point, Paul Collingwood shaped to drive Jade Dernbach and was bowled for 36.
Arshad resisted for 18 overs in making 15 before Tremlett claimed two more wickets through edged catches.
Last man Chris Rushworth then guided Tim Linley to first slip, leaving Mustard unbeaten on 45.
Both Surrey openers were out with the total on five, Harrison striking first when left-hander Rory Burns pushed forward and edged to Mustard.
Michael Richardson then held a good catch to his right at third slip to get rid of Arun Harinath off Rushworth and it became 20 for three when Vikram Solanki offered no stroke and was lbw to Harrison.
After Amla's exit, de Bruyn and Steven Davies went for their shots and added 47 before Arshad's double-strike. Davies was unbeaten on 36 at the close.
