Sussex completed a 148-run thrashing of Holland to go two points clear at the top of Group A in the Clydesdale Bank 40 on Saturday.
The Sharks set an impressive target of 271-2 in Amstelveen before skittling out the hosts for just 123 to claim their seventh win in eight games of the competition.
Holland won the toss and put Sussex in to bat and opener Ed Joyce fell for 21 when he was caught behind off Mark Cleary on the last ball of the seventh over.
But Chris Nash and Lou Vincent proceeded to take the Dutch bowling attack apart with a stand of 194 for the second-wicket.
Vincent smashed 102 from 87 balls, including five fours and a six, while Nash battered five fours and two sixes for his unbeaten 111-ball 116.
Vincent fell with 3.2 overs to go, caught Peter Borren, and Rana Naved-ul-Hasan chipped in with a quickfire 19 not out to complete the innings.
The hosts lost wickets steadily in reply, sliding to 32-5 after 12 overs but Tom de Grooth, who was Holland's top scorer with 30, led a brief rally to take his side closer to three figures.
But after he was dismissed lbw by Luke Wells in the 23rd over, the wickets began to tumble again and by the end of the 29th Holland were 100-8.
The visitors wrapped things up with 28 balls to spare, with Chris Liddle and Wells the pick of the Sussex bowlers, ending the game with figures of 5-18 and 3-9 respectively.
