West Indies have been fined and hit with a World Cup Super League points deduction for maintaining a slow over-rate in Sunday's third ODI defeat to New Zealand, the International Cricket Council (ICC) has announced.

Nicholas Pooran's side fell to a 2-1 series defeat on home soil with a narrow six-run loss in Sunday's decisive third meeting, as Kyle Mayer hit 105 – the second highest ODI score of his career – in vain.

West Indies will also be deducted two points from their Super League tally after being adjudged to have fallen two overs short of the target by the on-field umpires.

An ICC statement read: "West Indies have been fined 40 per cent of their match fee for maintaining a slow over-rate against New Zealand in the third and final ODI in Barbados on Sunday.

"In accordance with Article 2.22 of the ICC Code of Conduct for Players and Player Support Personnel, which relates to minimum over-rate offences, players are fined 20 per cent of their match fees for every over their side fails to bowl in the allotted time.

"In addition, as per Article 16.12.2 of the ICC Men's Cricket World Cup Super League Playing Conditions, a side is penalized one point for each over short. Consequently, West Indies will lose two points from their points tally during the Super League.

"Pooran pleaded guilty to the offence and accepted the proposed sanction, so there was no need for a formal hearing."

West Indies are currently seventh in the Super League standings, having posted just nine wins from their 24 games after New Zealand recorded successive wins over Pooran's side.
