The Sri Lankans had hit a One-day international world record total of 443-9 as they crushed the Dutch by 195 runs in the first encounter of this two-match series on Tuesday.
And although they couldn't quite match that feat this time, they were still in complete control again.
Sri Lanka recently completed a 5-0 One-day whitewash of England and were heavy favourites to continue their fine form against the Netherlands, one of the leading six Associate countries who are not a full Test playing nation.
The International Cricket Council (ICC) on January 1 decided to award full ODI status to games involving Associate countries.
Sri Lanka, who rested Sanath Jayasuriya, won the toss and opening batsman Tharanga blasted eight boundaries in his 72 from 72 balls to get the tourists off to flier.
Tillakaratne Dilshan provided able support with 66 from 59 deliveries but, although the majority of his team-mates got themselves in, no-one else managed to reach a half-century.
The Netherlands handed debuts to Pieter Seelaar and Eric Szwarczynski but medium-pacer Darron Reekers was the pick of his side's attack as he claimed three wickets.
Billy Stelling wasn't so fortunate as he conceded 91 runs from his 10 overs.
