DURHAM missed a chance to take a grip of the game when Ryan Buckley put down a return catch with Steve Davies on one.
That would have made it 138 for five, but at tea Surrey are 199 for four and after his debut wicket this morning Buckley has had no further reward for bowling all afternoon.
He thought he had Zander de Bruyn caught behind on 25, but the appeal was turned down.
The one wicket of the session went to Callum Thorp, who snared Arun Harinath for 53 with a skilful piece of bowling at a time when neither batsman looked in any trouble.
Thorp followed up a bouncer by pushing one wide of off stump, which the left-hander felt for and edged to Paul Collingwood at slip.
Harinath had begun to look a class act, especially in twice square driving Buckley for four with immaculate timing, while de Bruyn waited patiently for the bad ball.
Mark Wood tried to set him up for a leg-side catch, posting a leg gully then a forward short leg, and it almost worked. The ex-Somerset man was on 36 when Phil Mustard got his glove-tips to one, diving away to his left.
