Opening batsman Kraigg Brathwaite has been called up to West Indies' ODI side for their upcoming series against Pakistan in the UAE.
Brathwaite has played 31 Tests since his international debut in 2011 but is yet to play an ODI or a T20, reported cricinfo.
The T20I squad includes two uncapped players — allrounder Rovman Powell and wicketkeeper-batsman Nicholas Pooran.
Chris Gayle, having made himself unavailable for selection, is not a part of the T20 squad while Lendl Simmons has missed out due to medical reasons.
Batsman Evin Lewis and fast bowler Alzarri Joseph — who are uncapped in the format — are also part of ODI squad.
Lewis, who made his T20I debut earlier this year, recently scored a 48-ball century against India in Florida, while Joseph made his debut in the home Test series against the same opposition.
Pooran impressed in this year's Caribbean Premier League, scoring 217 runs in eight innings at a strike rate of 197.27 for Barbados Tridents, while completing eight dismissals behind the stumps.
The T20I squad does not include former captain Darren Sammy, who was axed from the role last month.
Sammy was also excluded from the T20I squad that played against India in Florida.
Gayle, Sammy, Dwayne Bravo, Lendl Simmons, Andre Russell and Samuel Badree were ineligible for ODI selection as they did not play domestic 50-over tournament last season, made mandatory by the WICB.
West Indies will start their tour with three T20Is against Pakistan, between September 23 and 27, followed by the three-match ODI series which starts from September 30.
The three-Test series, which includes a day-night match in Dubai, starts from October 13 and West Indies' squad for that format will be announced later.
