Sri Lanka captain Charith Asalanka won the toss and elected to bat in the first of the two-match one-day international series against Australia on Wednesday.
The series will be a warmup for the Australians ahead of the Champions Trophy to be played later this month in Pakistan. Sri Lanka did not qualify for the tournament.
Australia rested front-line players Travis Head, Josh Inglis and Glenn Maxwell. Sri Lanka made one change from its last ODI against New Zealand in Auckland in January — Dunith Wellalage replaced Chamindu Wickramasinghe.
