Derbyshire are staring down a fourth consecutive defeat after they ended the third day of the LV= County Championship Division One match against Sussex at Derby only 11 runs ahead with three second innings wickets standing.
Michael Yardy made 153 as Sussex took their first innings total to 401 and a lead of 178 with Derbyshire fast bowler Mark Footitt claiming a career-best 6-120, but their batting ine-up wqas then reduced to 189-7 at stumps.
Derbyshire avoided an innings defeat but Monty Panesar, Steve Magoffin and James Anyon all claimed two wickets to take Sussex to the verge of victory, with the home side's top score coming from 39 extras.
The home side's spirits would not have been lifted by the sight of Sussex captain Ed Joyce padded up and waiting to come in at number 11 following his return home on Thursday for domestic reasons.
Joyce watched Panesar drive Footitt down the ground for four before the England spinner tried to hook the next ball and was caught off his glove for 10.
Yardy reached his 150 with his 18th four which also took the visitors past 400 before Tim Groenewald then beat his attempted drive two balls later, but he and Joyce had already added 60 from 56 balls.
Derbyshire then started their second innings badly when Billy Godleman fell to a loose drive at Anyon in the third over and was lbw with only seven on the board.
Wayne Madsen and Chesney Hughes, who was batting with a fractured finger, provided the required application and dug in for 24 overs to take the score to 80 before Panesar drew Madsen forward and bowled him for 32.
Hughes resisted for nearly two-and-a-half hours before he miscued a pull at Steve Magoffin to mid-on and although Dan Redfern was dropped by Joyce at second slip on 15, he gifted Sussex his wicket with a firm-footed slash at Anyon fourth ball after tea.
Although the floodlights were on, there was a short stoppage for bad light before Derbyshire lost a fifth wicket when Chris Jordan had Ross Whiteley caught at third slip off a lifter for six.
Much now rested on Chanderpaul and the veteran West Indian dropped anchor for 155 minutes until Magoffin had him caught at second slip for a 119-ball 23 from one that moved away.
The light meant Sussex had to bowl spin at both ends and Panesar had Jon Clare caught at short leg off bat and pad with Derbyshire only six runs ahead, but Richard Johnson and Groenewald held on to take the match into a fourth day.
