Chasing a daunting 182-run target, Sri Lanka cruised home with two overs to spare, sealing their place in the Super Eight round. Nissanka dominated the Australian attack with a fluent knock filled with crisp boundaries and calculated aggression.
He was well supported by Kusal Mendis, who struck 51 off 38 deliveries to steady the chase, while Pavan Ratnayake remained unbeaten on 28 from just 15 balls to finish the job in style.
The commanding win boosts Sri Lanka’s momentum as they advance to the next stage of the tournament.
