Warwickshire's Dougie Brown helped Scotland claim their place in the 2007 World Cup, contributing to a resounding 98-run win against ICC Trophy holders Holland.
In a match reduced to 49 overs a side because of rain, the Scots were asked to bat and the innings was soon in trouble.
Fraser Watts and Ryan Watson fell early to Edgar Schiferli, but cavalier opener Paul Hoffmann continued to play his shots to reach 36 before getting caught in the slips off Darron Reekers.
Hoffmann's demise brought Cedric English and Gavin Hamilton together and they added 74 for the fourth wicket. Hamilton became Schiferli's third victim when he edged to wicketkeeper Jeroen Smits for 32.
The heavens then opened for nearly two hours but Scotland returned and added another 81 runs to set the Dutch 222 to win. Greig Williamson was left stranded at the end on 25 and Schiferli finished with three for 39 from his eight overs.
In reply Holland were never in the hunt to challenge the Scots total as opening bowlers Brown and Hoffmann bowled beautifully. Tom de Grooth was first to go when he edged Hoffmann to Watson at first slip for just nine.
Brown trapped Bas Zuiderent leg before soon after and when John Blain dismissed Tim de Leede and the dangerous van Bunge in successive overs the Dutch were in all sorts of trouble at 56 for four.
The Dutch never recovered from Blain's burst and it was left to spinners Watson and Gregor Maiden to finish the job off. Feiko Kloppenburg was last to go when Blain held on to a fantastic diving catch.
Scotland's win also secured top spot in Group B and they will now avoid hosts Ireland in the first knock-out stage of the competition, which starts in Dublin on Saturday.
Holland must win two knockout matches to have any chance of making the World Cup in the West Indies after Canada thrashed Papua New Guinea to take second place in the group.
