The grimaced celebration
Tamim Iqbal pierced the off-side field to find the boundary, which got him to 101 off 60 balls. He threw off his helmet and started celebrating, jumping high in the air. Upon landing, though, he held his right hamstring and grimaced. He had, in the ninth over, clutched the same area after completing a tight single. He proceeded with his celebrations undeterred, gesturing towards coach Chandika Hathurusingha, who flashed a smile. But the dressing room looked concerned as he walked back and hugged Shakib Al Hasan.
When Khawar Ali bowled Sabbir Rahman around his legs in the 16th over, the batsman kept shaking his head. He had turned around and seen the light on the leg bail come on as it fell off, with the wicketkeeper Sultan Ahmed quite far behind, but still did not seem convinced. The square leg umpire quickly went upstairs and replays suggested that the ball had indeed glanced the leg stump. You may have seen batsmen shaking their heads after being annoyed with their shot selection, but rarely does one do it after the bail has been dislodged.
When play resumed after a 45-minute interval in Oman's innings, Adnan Ilyas tapped a Mashrafe Mortaza delivery towards point and ran off, only to be sent back. Soumya Sarkar missed the throw. Adnan stood there, turned and gave Jatinder Singh an angry look and perhaps a word or two. Two balls later, the same thing happened, except that Soumya hit the stumps to find Adnan a few feet short. This time, Adnan swung his bat in anger and gave Jatinder a piece of his mind. Oman have not been shy to show their emotions on the field. Against Ireland too, Sultan had similarly lambasted Amir Ali for not responding to a call for a single.
The misguided heave
Khawar found a six despite having a hard time timing most of the balls he faced. In the third over, he went after Taskin Ahmed's short ball by attempting a heave over long-off. However, the impact and momentum took the ball towards the point boundary for a six, much like how Glenn Maxwell has done a few times recently. There have been plenty of mistimed sixes in T20s but with this one, the bat went one way and the edge took the ball to an acute angle, still going beyond the rope where the groundsman dropped the catch.
