Derbyshire slumped to an innings and 31-run defeat against Essex, despite a century from captain Wayne Madsen.
Essex were bowled out for 473 after resuming on 449-8 thanks to some late hitting from James Foster who made 72.
Trailing by 325, Madsen (112) and Chesney Hughes (80) shared Derbyshire's only notable stand of the game, as they put on 166 runs for the third wicket.
However Graham Napier's (4-64) fine spell helped dismiss Derbyshire for 294 to give Essex a comfortable win.
|Madsen stars for Derbyshire|
|Despite joining Derbyshire in 2009 and scoring 18 first-class centuries, Wayne Madsen's 112 was his first century against Essex.|
Derbyshire started their attempt at knocking off the mammoth first-innings deficit badly, losing Ben Slater for nought in the first over to Jamie Porter (2-32).
Once Hughes was bowled by Ravi Bopara (1-44), wickets began to fall at regular intervals with only Madsen looking fluent.
Madsen's dismissal to Napier, caught at slip by Alastair Cook, triggered a lower order collapse as Derbyshire's last five wickets fell for 21.
The victory was only Essex's second in Division Two of the County Championship this season.
Essex head coach Paul Grayson:
"It was a good performance and it was an important toss to win on day one with the cloudy conditions but we exploited them very well.
"Young Jamie Porter particularly did well for us on that first morning and then we produced a fine all-round performance with the bat to put us in a very strong position.
"We had to work hard for our wickets second time around but the boys kept at their task and got the rewards their efforts deserved."
Derbyshire coach Ant Botha:
"You hate to make excuses but clearly, it was favourable to bowl in the conditions on that first morning.
"To be fair to Essex, the bowlers put the ball in the right places and asked the right questions.
"We were pleased though with the way our guys bowled especially against their quality batting line-up and they kept up their energy levels and did all we asked of them."
