THE relentless accuracy of Steve Patterson undermined Durham as they struggled to 155 for eight at tea. It could have been worse had Jack Burnham, still there on 40, not been dropped on four by Alex Lees at first slip off Josh Shaw.

In a 14-over spell broken by lunch, Patterson recovered from conceding 18 in his first three overs to take four for 44.

Mark Stoneman was adjudged lbw when well forward without addition to his lunchtime 45 then a more confident shout was turned down before Paul Collingwood had scored.

The home captain looked anxious to get after Patterson, but after driving one four through the covers he went for a wider one and sliced it to backward point.

Excellent balls earned the next two wickets, Michael Richardson edging one which lifted and left him before Ryan Pringle groped forward and lost his off stump.

When Tim Bresnan replaced Patterson he also found extra bounce to have Usman Arshad caught behind.

Barry McCarthy helped Burnham to add 26 before being caught and bowled, via bat and pad, by Shaw.
