Gill shared a 95-run partnership for the first wicket with skipper Rohit Sharma, who dominated the team’s batting with 42.
Rohit missed out on a half-century after Chamika Karunaratne fell, but Gill continued the attack with Kohli and brought up his second ODI hundred, celebrating it with a punch.
Gill hit Jeffrey Vandersay for four fours in the over after the ton, but was soon bowled by Kasun Rajitha’s slower delivery.
