Now I realize why Bangladesh wanted to play the third day as well. This is a good batting pitch and playing longer would make the chances of it being a draw greater. They knew they didn't achieved any spectacular score so they were trying to stretch it longer but Sri Lanka when got the chance to bat knew from start they need to score fast. With Pathum Nissanka's 187, they made a quick 368 without playing the whole day. They would be aiming to score quick tomorrow and lead Bangladesh by 200 something and would rather try to allout Bangladesh than play the whole 4th day.
But in every circumstance, I see this match going towards a draw.
The match is almost ready to be a draw, but if the Sri Lankan team can bat well in tomorrow and take a good lead on run, then they might lose to Bangladesh, but since almost all of the Sri Lankan top batsmen are out and they have six wickets in hand, this may not happen tomorrow cause they need more 128 run then they will take lead so winning could be hard for the Sri Lankan team in this match but about the draw they way they were performing it is to be happening.
