Last year's T20 Blast winners Notts Outlaws wrap up their third win from four games in this season's competition to move into second place behind Worcestershire in North group.
Dan Christian (62 off 40 balls) and Tom Moores (53) saw them to 175-8 ina game reduced to 19 overs each after a rain hold-up towards the end of their innings.
Christian then took 3-34 as Derbyshire were restricted to 139-9 in reply, chasing a DLS reviosed target of 179, with Ravi Rampaul and Lockie Ferguson picking up six singles in a low-key final over with the win way out of reach.

Daryl Smit is leg-before to Harry Gurney for 15 and it's now just a question of whether Derbyshire can survive seven more balls to avoid being bowled out by Notts. They are 132-9 as last man Ravi Rampaul joins Lockie Ferguson in the middle.
Notts all-rounder Dan Christian finishes a good night's work by having Callum MacLeod caught at long-off for 48 with his final delivery. The Aussie adds figures of 3-34 to his earlier 62 and Notts are almost home and dry - it's a fair bet where the Man of the Match award is going. Derbyshire end over 17 of their 19 on 127-6.
We've had some great action around the various grounds this evening and it's left to Derbyshire and Notts to bring up the rear in the East Midlands derby.
Derbyshire have moved on to 109-7 after 15 overs, with Anuj Dal bowled by Ish Sodhi for 10, the leg-spinner finishing his four-over stint with 2-32.
Callum MacLeod is 43 not out, but the job in hand is surely beyond the Scot.
With five balls remaining, Gloucestershire win tonight's West Country derby in Bristol.
With eight balls remaining, Gloucestershire need seven runs to win.
Ian Cockbain (39 from 21 balls) has helped the hosts' cause significantly.
The Derbyshire wickets keep on falling. Wahab Riaz goes for six - caught by Steven Mullaney off Dan Christian, who is having quite a game after making 62 off 40 balls in Nottinghamshire's 175-8.
The trophy holders look to be cruising home here, even though Callum MacLeod is still there on 28 not out, with Derbyshire 83-6 after 12 of their 19 overs.
The visitors win! Chris Cooke slots the final delivery away for four runs. Glamorgan celebrate. What drama!
The three wides that Neil Wagner conceded in that final over were the difference.
More trouble for Derbyshire as Gary Wilson becomes the first victim of leg-spinner Ish Sodhi, caught by Paul Coughlin. Wilson only managed six and the home side are 81-5, chasing a revised target of 179 to beat Notts.
Neil Wagner bowls a wide... They're tied.
One run to win from the final ball. Extraordinary.
Glamorgan take a single and then two runs... Two more needed from the final ball. Neil Wagner bowls to Chris Cooke...
Essex's Neil Wagner is bowling the final over of the match at Chelmsford.
Chris Cooke takes a single from the first ball of it, before Wagner concedes two wides, and then Cooke finds two more, but then only a single, so he loses the strike.
Can Timm van der Gugten hit Glamorgan to victory?
Callum MacLeod and Wayne Madsen try to build some momentum for Derbyshire, who need to score 176 in 19 overs to beat neighbours Nottinghamshire. But their mini-stand is brought to an end as Samit Patel as Madsen lbw for six as he tries, unsuccessfully, to reverse sweep.
It leaves the home side on 63-4, replying to the Notts score of 175-8, with Gary Wilson the new batsman.
Chris Cooke's fourth six sets up a terrific-looking final over at Chelmsford. He's up to 50 now, from 24 balls.
Glamorgan need 11 to win from the remaining six balls.
Mark Cosgrove had no doubts about how good Ben Raine's innings was in Leicestershire's 100-run win over Birmingham Bears.
All-rounder Raine - who later took two wickets - scored a career-best 113 from just 46 balls including 10 sixes and eight fours.
His previous highest had been just 48.
Game, set and match to Surrey as Jade Dernbach has Danny Briggs caught by Matt Pillans in the 18th over to finish with figures of 3-31.
Pillans also bowled well, claiming 3-20, in a Sussex run-chase that never really got going after Aaron Finch's brilliant unbeaten 131, including seven sixes, saw the visitors to 192-3 from their 20 overs.
Phil Salt made 74 off 47 balls in reply, but only two other Sussex batsmen reached double figures as they were bowled out for 140 - and suffered their first defeat in this summer's Blast.
