The home side, seeking to make amends for failing to reach the knockout phase of the Champions Trophy in England this month, left veteran batsman Devon Smith and experienced fast bowler Tino best out of their final eleven.
Sri Lankan captain Angelo Mathews noted after the toss that he would have also chosen to bat first, given the unsettled weather conditions and concerns about preparation moisture in the pitch.
Opening batsman Upul Tharanga and spinner Ajantha Mendis, who both missed the Champions Trophy, are included in their final eleven.
