After a day of mixed fortunes Sussex skipper Chris Adams faces a tough decision over when to declare against Durham at Chester-le-Street.

An astonishing spell of four for six by Adams was not enough for Sussex to enforce the follow-on as they seek their fifth win in six matches.

The captain is on 33 not out as Sussex go into the final day on 135 for one in their second innings, leading by 217.

He could be influenced by an elbow injury to his leading wicket-taker Jason Lewry, who retired today just as the new ball was due.

Durham had already passed the follow-on target by then, but there was further frustration as Mark Robinson had to be removed for running down the wicket and Adams had to bowl again.

He finished with 4-28, beating the career-best 4-29 he took for Derbyshire against Lancashire at Derby in 1991, but Durham's last two wickets put on 115 before they were all out for 360.

Replying to 442, Durham were 222-3 when Adams introduced his gentle medium pace and induced a skied return catch from Nicky Peng off his first ball.

Paul Collingwood skied a catch to mid-wicket, Martin Speight was bowled shouldering arms and Danny Law was stumped down the leg side.

When Lewry had Graeme Bridge lbw Durham went into lunch on 245-8, still needing 48 to avoid the follow-on.

But wicket-keeper Andrew Pratt led the revival, making 51 not out, his second Championship half-century.
