Alexei Kervezee enjoyed a rare success as a bowler to give Worcestershire a second breakthrough before lunch on the third day of the LV = County Championship Division One clash with Sussex at Hove.
Kervezee bowled off spin and picked up the third wicket of his career to dismiss first innings century-maker Matt Machan lbw for 55.
It ended a stand of 119 in 27.1 overs with Sussex skipper Ed Joyce.
Joyce was unbeaten at lunch on 61 with Sussex 131-2 off 34 overs – a lead of 87.
Charlie Morris was the pick of the Worcestershire bowlers during an impressive initial seven over spell.
Morris was quickly into his stride and broke through in the third over of the morning.
Luke Wells (4) was undone by a lifting delivery and Alex Gidman at first slip held onto a sharp catch away to his right with the total 10-1.
Jack Shantry continued to share the new ball and was swept for six by Joyce.
First innings century-maker Machan survived a difficult chance to Tom Fell at third slip off Morris.
Morris was troubling both batsmen and Joyce picked up a streaky boundary with an edge to third man.
Machan was less convincing than in his superb first innings knock but a straight drive for four off Andrew brought up the 50.
The all-rounder bowled three overs but then left the field but returned after a short spell.
Spinner Sachithra Senanayake began with a maiden before Shantry returned to replace Morris after an excellent seven over spell.
The former Oxford MCCU graduate deserved better overall figures than 9-1-42-1 at that stage.
Joyce, who scored eight Championship centuries last season, reached his half century off 77 balls with seven fours and a six.
The century stand with Machan came up in 22 overs.
Alexei Kervezee, who batted well for his 93 yesterday, was given a rare bowl in the role of spinner and troubled Machan immediately before dismissing him.
Machan faced 79 balls and struck six fours.
