|LV= County Championship Division Two, Derby|
|Derbyshire 356 & 296 beat Worcestershire 385 & 129 by 138 runs|
|Derbyshire 22 pts, Worcestershire 6 pts|
Wes Durston took a career-best 5-19 to help Derbyshire to a surprise win over Division Two leaders Worcestershire.
New Zealand paceman Mitchell McClenaghan took 5-78, but Derbyshire captain Wayne Madsen made 98 as they totalled 296, a lead of 267.
Worcestershire lost two early wickets to Mark Footitt (2-46), who also took a catch to dismiss Daryl Mitchell (15).
He was the first victim of off-spinner Durston, who ran through the tail as they collapsed to 129 all out.
Worcestershire had been set a victory target of 268 in 57 overs, but Durston proved the destroyer, taking his final four wickets inside seven overs.
In all, 18 wickets fell on a frantic day's play but, despite suffering a second successive defeat, Worcestershire still have a seven-point lead over Hampshire and, more crucially, they are 39 points clear of Surrey in third.
Worcestershire director of cricket Steve Rhodes told BBC Hereford & Worcester:
"It was never going to be easy, because they had two good spinners and the wicket was turning and bouncing.
"Whilst we gave it a good shot, and there were some good efforts down the order from Jack Shantry and Mitchell McClenaghan, losing your top five batters in 25 overs is the biggest blow.
"That's something they've got to try and correct. They've been good this year and they're allowed to make mistakes as long as they learn from them.
"Ultimately if we had taken a few chances, it might have been a lot less of a target and it might have been a different result. We've caught well this summer, but we put too many crucial ones down in this match."
