This one is kind of hard to predict. West Indies do not have a great bowling attack but so doesn't Netherlands. Both will rely on the batting heavily. The way the Dutch batted against a decent English bowling attack I suspect West Indies won't get an easy win.
But all set aside I think West Indies will eventually win the match. Both teams have their own set of weaknesses and strengths. I think a score of around 275 from West Indies and they might be able to defend it. If Netherlands bat first then they would get below 250. All depends of Christopher Gayle.
