Bangladesh's runs are mainly due to three players, especially Nazmul Shanto, Mushfiqur Rahim, and Liton Das. These three mainly scored runs, and none of the other batsmen were able to collect well, which is why Bangladesh's collection was only done by these three. Bangladesh is batting well against Sri Lanka in comparison and if Sri Lanka can bat for two sessions tomorrow, they will definitely give Bangladesh a target of runs. Bangladesh mainly batted and kept the wickets intact in a defensive mood but could not increase the run rate. But Sri Lanka batted and was able to increase the run rate.
Mushfiqur Rahim scored the maximum amount of runs, and he is 38 years old. And this is the problem with Bangladesh. Most of their consistent players are well past the retirement age. Younger players such as Litton Kumer Das are just not being consistent. They are slightly better in the bowling department, with Mustafizur Rahman and Taskin Ahmed performing decently over the past few years (same can be said about some of the spinners). But as far as batting is concerned, they have limited room for maneuverability.
