Worcestershire sealed a sixth Specsavers County Championship win of the season by nine wickets after bowling out Derbyshire for 266 on the final afternoon of the season at New Road.
The County were left a 40 target in 18 overs after bringing about a dramatic Derbyshire collapse in which the last five wickets fell in 7.1 overs for 11 runs.
Skipper Daryl Mitchell (28) and Tom Fell (15) saw Worcestershire across the finishing line with 8.3 overs to spare.
Victory enabled Worcestershire to seal third spot in the table behind champions Essex and Kent.
It looked like Wayne Madsen was going to defy the victory bid of Mitchell's side with an excellent century.
But then Mitchell did the trick after introducing himself into the attack with two wickets in two overs, Brett D'Oliveira picked up two in two balls and Miguel Cummins polished off the innings.
The home side made good progress in the morning session in their bid to record a sixth Championship win of the season by claiming three more wickets after Derbyshire resumed on 15-1.
Joe Leach struck in the third over of the day when Alex Hughes (12) edged to Tom Kohler-Cadmore at first slip.
It was Leach's 65th victim of the season to make him the leading wicket-taker in Division Two.
Cummins accounted for Derbyshire skipper Billy Godleman (16) who went for a pull and lofted a catch into the hands of Ed Barnard at fine leg.
Then Barnard came into the attack and ended a stand of 45 in 10 overs between Madsen and Tom Wood.
Wood (10) played down the wrong line and was caught by keeper Ben Cox.
The fifth wicket pair of Madsen and first half century-maker, Harvey Hosein, held up the home side in the post lunch interval.
Madsen went to his half century off 72 balls with his ninth boundary – an on drive off Cummins – and the same stroke brought up the 50 partnership in 11 overs.
The pair continued to score steadily and Madsen reached three figures with a single off George Rhodes – from 122 balls with 15 fours and a six.
But Madsen failed to add to that tally before Charlie Morris trapped him lbw after a stand of 124 in 26 overs with Hossein.
Derbyshire eventually wiped out their arrears with 39 overs remaining and Hosein completed a fifth successive half century from 115 balls with three fours.
But Worcestershire skipper Mitchell revived victory hopes with two wickets in his first two overs after entering the attack at 255-5 after 73 overs.
Tom Milnes (36) and Greg Cork (4) were both bowled and then Brett D'Oliveira struck twice in two balls.
Hosein (59) was caught at short leg by Fell and then Will Davis (0) was lbw to complete a king pair.
Cummins wrapped up proceedings as Tony Palladino (4) also fell lbw.
When Worcestershire set out in pursuit of their modest target, D'Oliveira (0) was caught off a leading edge at mid off during Milnes' first over.
