Rahmat Shah and Ibrahim added 29 runs in the second wicket stand and were looking forward to building the innings slowly. But it was Taijul who scalped another wicket to break the potential big partnership removing Ibrahim for 21.
In the second wicket stand, Rahmat and Hashmatullah added another 29 runs, and they were also looking comfortable in the middle. They were playing Bangladesh’s four-pronged spin attack with much concentration.
But at the stroke of the first break of the day, Mahmudullah sent Hashmatullah backed to the dressing room. Soumya Sarkar took a blinder on the second attempt.
Hashmatullah was looking to cut the ball but it was too fast to manage. And eventually, he ended up losing his wicket right before the lunch, which left the tourists struggling at the end of the season at 77 for three in 32.4 overs.
However, after the lunch, Rahmat resumed the innings with the former captain Asghar and they are helping Afghanistan to put up a good score as they remained unbeaten while the tea break.
