Sussex paceman Corey Collymore captured Michael Di Venuto and night-watchman Mark Davies as Durham made a bad start in replying to Sussex's below par 214.

Mark Stoneman also fell to a slip catch off Jason Lewry as the visitors closed on 10-3.

It was a good response by defending champions Sussex who were earlier hit by a career best from Ben Harmison of 4-43, while brother Steve claimed 3-35.

Sussex chose to bat on a humid morning and soon lost half their side for 79.

Opener Chris Nash (75) and debutant Rory Hamilton-Brown (62) shared a six-wicket stand of 84 in 25 overs.

But Luke Wright (15) and Robin Martin-Jenkins (22 not out) were the only other batsmen to make double figures.
