West Indies captain Floyd Reifer won the toss on Friday and chose to bat in the third and final one-day international against Bangladesh.
The hosts, trailing 2-0 in the series, made two changes to the team that lost the second match in Dominica last Tuesday.
The 19-year-old opener Kieran Powell is given his debut for the match at Warner Park at the expense of Dale Richards, while left-arm spinner Nikita Miller replaces Rawl Lewis, who has a left thigh strain.
Bangladesh also made two changes, with Nazmul Hossain and Mahbubul Alam coming in for fellow seamers Rubel Hossain and Syed Rasel.
West Indies: Kieran Powell, Andre Fletcher, Devon Smith, Travis Dowlin, Floyd Reifer (captain), David Bernard Jr., Devon Thomas, Darren Sammy, Nikita Miller, Kemar Roach, Gavin Tonge.
Bangladesh: Tamim Iqbal, Junaid Siddique, Mohammad Ashraful, Raqibul Hasan, Shakib-al-Hasan (captain), Mushfiqur Rahim, Mahmudullah, Naeem Islam, Abdur Razzak, Nazmul Hossain, Mahbubul Alam.
