AN unbroken stand of 86 between Keaton Jennings and Paul Collingwood took Durham to 191 for four at lunch, 40 ahead.

The only casualty of the morning was Michael Richardson, who had the misfortune to be run out for 13.

A ball from Steve Patterson thudded into his pads and ran off towards square leg. Jennings called him for a single, but he hesitated before responding and was well short when Ben Coad's throw hit the stumps.

On 105 for four Durham were still 46 behind with Patterson and Tim Bresnan offering nothing.

It was not until the tenth over that Jennings added to his overnight 46, reaching 50 off 138 balls.

Collingwood's frequent steers to the third man boundary finally persuaded Yorkshire to post a fielder there, although he was fortunate to survive an upper cut off Josh Shaw, which brushed Andy Hodd's gloves.

He was on 19 but had progressed to 47 at lunch with Jennings on 82.
