Brown and Magoffin lead Sussex charge
Ben Brown struck a fluent unbeaten 76 and Steve Magoffin produced a superb spell with the ball to help Sussex step up their bid for second place in the LV= County Championship Divison One table on the first day against Durham.
Brown went in with his side on 67 for five and helped them to 211 all out before Magoffin produced a devastating spell with 3-19 in 10 overs.
Durham had recovered from 65 for four thanks to a stand of 53 between Mark Stoneman and Paul Collingwood when the Australian seamer returned for a further five overs.
But it was Monty Panesar who ensured 16 wickets would fall on the opening day by taking 2-4 in five overs as Durham closed on 131 for six.
Collingwood tried to hit his former England team-mate over the top and was caught at mid-on for 19, then Stoneman edged the same bowler to Michael Yardy at slip.
Stoneman was the only batsman on either side able to counter the new ball as the left-hand opener made 53, despite batting for half his innings with a runner after suffering a hamstring injury.
Although they had more at stake than Durham, it was Sussex who took the opportunity to give some experience to a few youngsters.
Neither Murray Goodwin nor Matt Prior were included, while Ed Joyce is with the Ireland squad preparing for the World T20 in Sri Lanka and Luke Wright is on England duty.
Sussex's side included 21-year-old batsman Matt Machan, left-arm swing bowler Lewis Hatchett, South African all-rounder Kirk Wernars and giant all-rounder Will Adkin.
After losing the toss, acting captain Chris Nash drove at the seventh ball and edged to first slip as Chris Rushworth opened up with an excellent spell.
Graham Onions struggled but a change of ends paid dividends as he quickly took two wickets.
Callum Thorp was the first to strike from the Finchale End, having Luke Wells caught behind for 25, although the left-hander clearly did not agree with the decision.
Once the ball had stopped swinging batting became easier, which allowed Brown and Wernars to put on 106, and Durham needed a run-out to make the breakthrough.
Brown had just reached 50 off 59 balls when he drove into the covers and went for a run, only for Wernars, three short of his career-best of 53, to be stranded by Michael Richardson's diving stop.
Brown looked very comfortable and timed the ball superbly as he smashed 13 fours in making his runs off 102 balls.
Durham also scored fluently against all bowlers other than Magoffin and Panesar, but it was Hatchett who struck first when Keaton Jennings padded up to his sixth ball and fell lbw.
Richardson was Magoffin's first victim, falling lbw third ball, before the bowler struck twice more. Ben Stokes was beaten on the drive to be bowled and Dale Benkenstein played back defensively to a ball which trimmed his off bail.
