Kent reached the Twenty20 Cup semi-finals for the third successive year after thrashing Durham by 56 runs.
Chasing 150 at Canterbury, the Durham top order was blown away by the 2007 champions as they slumped to 39-6.
Dale Benkenstein made 47 but could not prevent his side being dismissed for 93 - their lowest score in the competition - as James Tredwell took 3-18.
Kent had earlier stumbled to 149-7 after Joe Denly (31) and Rob Key (30) had put on 69 for the first wicket.
That had got the home side off the a flying start, but Ben Harmison (3-24) checked their progress by removing both openers and then running out Geraint Jones with a smart piece of fielding.
When Martin van Jaarsveld gave Mitch Claydon his third catch, this time off Gareth Breese, Kent were suddenly 87-4.
Darren Stevens and Justin Kemp threatened to get them back on track, but after they both fell in quick succession it needed a spirited seventh-wicket stand of 28 between Azhar Mahmood (14 off 11 balls) and Ryan McLaren (21 not out off 13 balls) to get the hosts towards the 150-mark.
Their bid to keep the talented Durham batting line-up quiet then got off the to perfect start when Wayne Parnell (2-20) had Phil Mustard caught by Tredwell off the first ball of their reply.
He struck again in his following over, having Australian David Warner - back from Queensland especially for this game - caught at slip by van Jaarsveld, also without scoring to leave Durham 5-2.
Kyle Coetzer and Benkenstein added 18 for the third wicket before the wheels really started coming off for the visitors.
Coetzer was smartly stumped by Jones off Simon Cook before Ian Blackwell became the third Durham batsman to be dismissed for a duck when he was run out.
Will Smith and Gareth Breese both fell cheaply to leave the visitors out of it at 39-6.
And although Benkenstein tried to rally his side, wickets continued to fall as Tredwell added the scalps of Liam Plunkett and Harmison to that of Breese.
Mahmood then wrapped up the game with 16 balls left, having Benkenstein caught by Stevens at deep cover and Claydon caught behind off successive balls.
