Maiden ODI hundreds from Kyle Mayers and Shamarh Brooks and an all-round bowling display have helped the West Indies beat the Netherlands by 20 runs and script a 3-0 series win.
Needing 309 to win, the Dutch got off to a near-perfect start as Max O'Dowd (89 off 121), and Vikramjit Singh (54 off 55) accumulated their third consecutive 50-plus stand.
The duo added 98 runs in 17.1 overs, and in the process, the Netherlands became the first associate nation to rack up three 50-plus stands in a row against a full-member.
The opening stand was eventually broken by Kyle Mayers, who knocked over Singh for a 55-ball 54.
However, O'Dowd and Musa Ahmed (42 off 42) continued to chip away, adding 66 runs for the second wicket before the latter was dismissed by Hayden Walsh Jr.
O'Dowd couldn't quite accelerate at the backend, which created a lot of pressure on the incoming batters as they had to go for their shots from the first ball.
De Leede (25 off 24) and Scott Edwards (18 off 19) scored at a run-a-ball, but the asking rate proved to be their demise as they fell to the spin duo of Akeal Hosein (2-52 in 10) and Walsh (2-54 in 10).
Logan van Beek (15 off 14) and skipper Seelaar tried their best, but it ultimately proved to be a bridge too far to scale.
Maiden ODI 100s from Mayers, Brooks guide WI to 308
Earlier, the West Indies rode on maiden ODI hundreds from the duo of Kyle Mayers (120 off 106) and Shamarh Brooks (101* off 115) to post a more than competitive total of 308/5 in their quota of 50 overs.
Unlike the previous match where the tourists' top-order fell away stunningly, the Nicholas Pooran-led unit got off to a decent start as the opening duo of Mayers and Shai Hope (24 off 43) added 58 runs in just over 11 overs.
Bas de Leede ended the partnership with the dismissal of Hope.
However, Mayers and Brooks proceeded to launch a stunning assault on the Dutch bowlers. The duo added 184 runs for the 2nd wicket- the highest by any batting pair in the country.
Mayers, who smashed as many as 7 sixes and 8 fours, brought up his maiden ODI hundred in just 96 deliveries. However, he was eventually dismissed at 120 by pacer Ryan Klein.
His dismissal triggered a collapse as Pooran (7 off 7), Brandon King (10 off 12), and Hosein (3 off 5) all perished cheaply.
However, Brooks stayed till the end to complete his maiden 100 and, along with Nkrumah Bonner (19* off 16), took the West Indies past the 300-run mark.
