West Indies captain Darren Sammy won the toss and opted to bowl against Sri Lanka in the World Twenty20 Super 10 match at Bengaluru's M Chinnaswamy Stadium on Sunday.
West Indies, champions in 2012, completed a six-wicket win over England in their Group One opener in Mumbai on Wednesday thanks to an unbeaten Chris Gayle century.
Sammy made one change to the side that beat England, bringing in Andre Fletcher in place of medium-pacer Jerome Taylor.
Defending champions Sri Lanka, missing pace spearhead Lasith Malinga due to a knee injury, beat Afghanistan by six wickets on Thursday and skipper Angelo Matthews also made one change.
Malinga's replacement, leg-spinner Jeffrey Vandersay, comes straight into the side in place of off-spinner Shehan Jayasuriya.
