Bangladesh will not improve on their batting weakness. Like the Test and ODI series, Bangladesh will lose the T20 series as well, it is certain. It is not surprising if Bangladesh does not win even a single match. It is not possible for Bangladesh to win against them at Sri Lanka's home ground with such bad batting.
Sri Lanka had scored 99 runs in 9 overs. I thought the match would be over within 15 overs. But due to the slow batting of Kusal Perera and ABhishek, Sri Lanka had scored 159 runs in 19 overs. The match was completely under Sri Lanka's control. So even though they batted slowly, the team did not face any problem. The second match will be held on July 13 in Dambulla. I do not expect anything better from the Bangladesh team.
Yes especially after their first T20 match and earlier Test and ODI games batting is causing problems and Sri Lanka will win all matches even though they are playing at home.
You clearly thought Sri Lanka would finish first T20 much faster. But Kusal Perera and Abhishek batted slowly making game last longer and that is right that Sri Lanka was fully in control. I hope Bangladesh will try yo their best in their next game. But the squad is still not looking good. Let's see what will Bangladesh do next?
In the first innings, Bangladesh were under pressure and could not score as they needed. On the other hand, Sri Lanka batted well and tried to control themselves. Pathum Nissanka was especially aggressive in the beginning and was able to control the match. When there is no pressure in the match, Kusal Perera scored very slowly, which is what the batsman did to ensure victory without taking risks. However, I will agree with you that the T20 squad does not seem good for some reason. The team had 5 wickets in hand but they finished the innings at only 154
runsscore, which seemed a bit unusual. They needed to play more aggressively.
