|LV= County Championship Division One, New Road (close, day one)|

|Sussex: Yet to bat|
|Sussex 3 pts, Worcs 0 pts|
England fast bowler Chris Jordan returned his first five-wicket County Championship haul in 16 months to give Sussex the edge against Division One relegation rivals Worcestershire.
Jordan struck twice early on to reduce the home side to 13-2 before an 80-run third-wicket stand between Joe Clarke (40) and Brett D'Oliveira (38).
The home side then slumped from 93-2 just after lunch to 117-7.
Worcestershire recovered to reach 185-9, but Jordan still ended with 5-57.
In a seven-over opening spell, fit-again Jordan did the early damage in only his second Championship appearance following a lengthy absence with a side injury.
|Sussex have the edge at New Road|
|Worcestershire have won just once in nine home games against Sussex.|
|Seventh-placed Sussex are four points better off than Worcestershire.|
|It is the first time they have won the toss against Sussex in seven games.|
Jordan had home skipper Daryl Mitchell unluckily caught by Chris Nash from a knock-up by Michael Yardy at second slip before flattening Tom Fell's off stump. He then returned in the afternoon session for another productive burst, taking three more wickets in nine overs.
He bowled Clarke for 40 before D'Oliveira gloved a catch to keeper Ben Brown after attempting to pull Steve Magoffin.
Jordan enjoyed a fourth success when in-form Ross Whiteley drove loosely, edging to second slip, before home wicketkeeper Ben Cox shouldered arms and was bowled.
Alex Gidman (37 not out) got help first from Jack Shantry and then Pakistan spinner Saeed Ajmal before rain came to Worcestershire's rescue and play was called off an hour into the evening session.
Worcestershire director of cricket Steve Rhodes told BBC Hereford & Worcester:
"Chris Jordan bowled very well. 'Dolly' and Joe Clarke put together a good partnership and 'Giddo' has played nicely towards the end.
"But, apart from that, some of our shot selection and execution was very poor. I'm very disappointed.
"Having won the toss and batted on a used wicket, we certainly should have been in a lot better position than this."
Chris Jordan told BBC Radio Sussex:
"There was a real focus this week on guys really studying the opposition and how we can impose our strengths on them and we displayed something close to that.
"From ball one, Maggs and myself set the tone quite well followed up by everyone else.
"We didn't quite get the rewards in that first session but we still put the ball in the right areas, on that nagging length, on a slow pitch and we got some rewards in the end and put ourselves into a decent position."
