|Lancashire 169-3 (19 overs) beat Derbyshire 149-5 (19 overs)|
A county record fourth-wicket stand of 131 between Steven Croft and Karl Brown helped Lancashire to a second straight T20 Blast win at Derbyshire by 20 runs.
Croft (76 not out) and Brown (67 not out) took the visitors from 38-3 in the sixth over up to 169-3 in a match reduced to 19 overs a side by rain.
Stephen Moore (40) led the way against his former county but when he was run out by Croft their run chase stalled.
Kabir Ali (3-27) was the pick of the attack as Derbyshire ended on 149-5.
Croft and Brown's spectacular partnership was the second T20 record stand for Lancashire inside a week after Tom Smith and Paul Horton shared 128 for the third wicket in last Saturday night's 12-run win over Worcestershire.
Croft's knock came off 52 balls, with six fours and three sixes, while Brown plundered his runs off 50 deliveries, hitting six fours and two sixes, as the home attack suffered.
Victory took Lancashire into a share of the lead of the North Division with Northants.
