Sri Lanka needs to lift its game on fielding to have a shot at this year's T20 World Cup title, newly installed short-format captain Wanindu Hasaranga said Saturday.

Hasaranga is riding high after a career-best 7-19 against Zimbabwe during Thursday's ODI decider and will be making his debut as skipper on Sunday as the 20-over leg of the tour begins.

Poor fielding has been a running problem for the Sri Lankans in white-ball cricket, with 16 dropped catches at last year's one-day World Cup in India confining them to a second-last place finish on the points table.

"I have told the team at the outset that fielding will be very important," he told reporters.

"No matter how well you bat or bowl, if you don't field well then you'll struggle to make it to the side. Fielding is non-negotiable," he added.

"We have another five months for the World Cup... Fielding is the easiest way we can improve our cricket and it makes a lot of difference between winning and losing in T20 cricket."

Hasaranga returned to internationals on Thursday for the first time in six months following a hamstring injury, making a splash with a new ODI bowling record for R. Premadasa Stadium in Colombo.
