It was Shakeel who drove a ball towards mid-off on the bowling of Nahid Rana. Shoriful Aslam, placed at mid-off, managed to get his hand on the ball, hence reducing the speed. Though his fielding prevented the ball from touching the boundary rope, the Pakistani duo still managed to run between the wickets and complete four runs.
The ball stopped near the long-off boundary after hitting Sharful's hand, prompting Najmul Hossain Shanto to hunt it down.
Shanto had to run from the mid-on region all the way to the boundary down the ground to pick up the ball, hence giving the batters ample time to run four.
The non-striker Mohammad Rizwan seemed to be quite tired at the end of the act, and threw his gloves and bat on the ground to let himself catch his breath.
