West Indies captain Chris Gayle won the toss and opted to bat in the first one-day international against Pakistan at the Sheikh Zayed Stadium here on Wednesday.
Pakistan received a setback when their ace paceman Shoaib Akhtar was ruled out of the match after pulling a calf muscle in his left leg during team practice on Tuesday.
He was replaced by 29-year-old fast bowler Abdur Rauf.
West Indies included left-arm spinner Nikita Miller and all-rounder Lionel Baker, 24, making his one-day debut.
The three-match series is being played at the neutral venue after West Indies refused to tour Pakistan over security fears.
