Nottinghamshire strengthened their position at the top of the Twenty20 North Division with a crushing eight-wicket victory over Derbyshire in the floodlit match at Derby.
The Phantoms were always struggling when they could manage only 114 for eight after being put in and the Outlaws reached their target of 115 in the 17th over.
Darren Pattinson was the star for the visitors with a devastating spell of three for four in six balls that sent the Phantoms crashing to 36 for three and they never recovered despite a defiant 45 from 38 balls by James Pipe.
The Outlaws were never under serious pressure and an opening stand of 84 between Will Jefferson and Adam Voges settled a one-sided contest with a violent cameo of 17 from Chris Cairns sealing victory with 21 balls to spare.
Derbyshire's fourth defeat dealt a serious blow to their hopes of reaching the knock-out stage but the Outlaws are now well placed to make the quarter-finals.
They played impressively after Chris Read won the toss with Pattinson and Charlie Shreck keeping the batsmen in check on a slow pitch.
Dominic Telo hit two fours but then cut Pattinson to gully and the seamer then yorked Greg Smith for five in his next over.
Wavell Hinds made only one before he lobbed a gentle catch to backward point and then Dan Birch was sent back and run out by a direct hit by Voges at mid-on.
John Sadler was bowled for a duck pushing forward at Andre Adams and when skipper Rikki Clarke top-edged a pull at Paul Franks, Derbyshire had slumped to 47 for six.
But Pipe pulled Adams for the first four in six overs and with Graham Wagg, added 31 before Adams trapped Wagg lbw for 12.
Pipe made sure his side passed three figures with some punishing blows against Mark Ealham who was driven for four and pulled for six in an over which cost 16, the most expensive of the innings.
Pipe was bowled going for another big hit off Paul Franks and the total was never likely to stretch Nottinghamshire unless they lost early wickets.
Jefferson and Voges made sure that did not happen as they found the gaps to leave another big home crowd frustrated as the Outlaws strolled to the finishing line.
Voges hit eight fours in his 45 off 35 balls before he was bowled coming down the pitch at off-spinner Jake Needham and Jefferson's well-paced innings of 43 from 45 balls was only ended by a leaping catch by Pipe in the 15th over.
Cairns finished the game in style with a salvo of boundaries, including a big six over wide long-on off Clarke, and the Outlaws now have 10 points while the Phantoms need to win their last four matches to have any hope of qualifying.
