Openers Pathum Nissanka and Kusal Perera powered Sri Lanka past 100 after they elected to bat first against fellow winless Australia in a World Cup clash on Monday.
The right-left batting pair of Nissanka and Perera took on the opposition bowlers with regular boundaries -- 14 between them -- at Lucknow's Ekana Stadium.
Perera reached his fifty with a boundary off Marcus Stoinis amid applause from the dressing room and a few Sri Lankan fans at a largely empty 50,000-seater stadium.
Nissanka soon got his second successive half-century as Sri Lanka reached 114-0 in 20 overs.
Sri Lanka's new captain Kusal Mendis named two changes to the team, which has scored over 325 runs in each of their two losses and are looking for a first win of the tournament.
Five-time winners Australia, led by Pat Cummins, have also lost their first two matches after they went down to India by six wickets and then suffered a 134-run thrashing against South Africa.
