Visitors Australia took an unassailable lead in the three-match T20I series, having won the first two games in Colombo.
The teams now head to Pallekele for the final T20I.
The hosts were completely outplayed in the first game as they were dismissed for a 128 and Australia chased the total in 14 overs with all 10 wickets in hand.
Even though Sri Lanka were dismissed for four less runs in the next game, their bowlers gave Australia a hard time chasing 125, which they did with three wickets in hand.
The 3rd T20I will kickstart at 07:00 pm today.
Sri Lanka’s major concern has been their batters who have failed to make big scores.
If there has been a silver lining for the home team, it is in Charith Asalanka who has played crucial knocks of 38 and 39 in the two games.
Although it is a dead rubber, Sri Lanka would go into the final T20I match wanting to win and end the series with some positives to look back on.
The Pallekelle International Cricket Stadium provides a neutral wicket where both the departments are expected to receive a reasonable amount of assistance from the surface.
Spinners will be crucial in the middle overs.
