Bangladesh held off a late charge from the West Indies to claim a series-clinching 18-run win in the decisive third and final match of their one-day international duel at Warner Park on Saturday.

After Tamim Iqbal's second hundred of the series and a quick-fire unbeaten half-century by Mahmudullah paced the visitors to a formidable 301 for six, the hosts were restricted to 283 for six in reply despite a rampaging unbeaten 74 off just 41 balls by Rovman Powell.
