West Indies has won the toss and chosen to bowl first under cloudy skies in Nottingham in their first match in this World Cup against Pakistan.
Pakistan included fast bowlers Wahab Riaz and Mohammad Amir, who were both brought into the World Cup squad from the cold late on in response to the run of poor results leading into the tournament.
There were no surprises in the West Indies team, with captain Jason Holder saying Evin Lewis and Shannon Gabriel were not fit to start.
Chris Gayle is in prime form ahead of his last World Cup and the 39-year-old opener's first big knock could come at Trent Bridge, where the boundaries are short and England has hit the two biggest ODI scores in history since the last World Cup.
Conditions are warm and overcast, according to UNB.
West Indies: Chris Gayle, Shai Hope, Darren Bravo, Shimron Hetmyer, Nicholas Pooran, Andre Russell, Jason Holder (captain), Carlos Brathwaite, Ashley Nurse, Sheldon Cottrell, Oshane Thomas.
Pakistan: Imam-ul-Haq, Fakhar Zaman, Babar Azam, Haris Sohail, Sarfaraz Ahmed (captain), Mohammad Hafeez, Imad Wasim, Shadab Khan, Hasan Ali, Mohammad Amir, Wahab Riaz.
