Nissanka, Mishara and SL bowlers trample Bangladesh in NRR-boosting win

They were locked 8-8 in T20Is in the decade leading up to this match, and all signs pointed to the first close contest of this Asia Cup after it kicked off with four mismatches. It was a bit of an anticlimax in the end, however, with Sri Lanka brushing Bangladesh aside by six wickets, with 32 balls remaining.

Given the high stakes of this group-of-death contest, Sri Lanka got everything they wanted from it: two points and a massive net-run-rate boost. Bangladesh, who had already copped criticism for taking 17.4 overs to chase down 144 against Hong Kong, now face an uphill task to qualify for the Super Four.

Sri Lanka dominated the match from its extraordinary start - Nuwan Thushara and Dushmantha Chameera bowled back-to-back wicket maidens with the new ball - to its breezy finish, with Bangladesh only really competing during an unbroken sixth-wicket stand of 86 between Shamim Hossain and Jaker Ali.

That partnership, which began at 53 for 5, gave Bangladesh some sort of total to bowl at. Very quickly, though, Pathum Nissanka's fluency and Kamil Mishara's power made it look like no sort of total. Nissanka scored 50 off 34 balls and became the quickest Sri Lankan batter to 2000 T20I runs, while Mishara finished unbeaten on 46 off 32.

Sri Lanka found new-ball swing after they chose to bowl, but that couldn't have been the only reason why Tanzid Hasan and Parvez Hossain Emon struggled to the extent they did. There were signs that this was a slightly two-paced pitch when Tanzid kept failing to find the middle of the bat - or the gaps - in the first over (though two of the mishits were off full-tosses), before Thushara swung his sixth ball through his gate as he attempted a get-out-of-jail drive on the up.

The second-over contest between Chameera and Emon was similar, though it only lasted four balls. This time, the on-the-up drive ended up as an outside edge to the keeper, with the ball swinging less than the batter expected. With Chameera rounding off the over with a pair of dots to No. 4 Towhid Hridoy, the scoreboard was an extraordinary sight: 0 for 2 in two overs.

Bangladesh sank deeper into misery in the fifth over when Hridoy was run out going for a sharp and needless third run, but Litton Das made sure they didn't let Sri Lanka have it all their own way. When they tried to slip in a quiet over from their fifth bowler Dasun Shanaka, Litton went after him - after edging his first ball just short of a diving fly slip - and hit him for three fours in the sixth over.

That did not signal a shift of momentum, though, as Wanindu Hasaranga, who had missed Sri Lanka's recent tour of Zimbabwe with a hamstring injury, came on in the eighth over and made an almost instant impact, trapping Mahedi Hasan lbw with his second ball, a trademark wrong'un.

He came close twice more with the wrong'un. Litton, given out on-field, successfully reviewed an lbw decision against him, with the inside edge coming to his rescue. Then Jaker, beaten comprehensively while defending off the front foot, was saved by the bails staying put after the ball brushed the off stump.

Hasaranga did get a second wicket, two balls later, with Litton gloving an attempted reverse-sweep to the keeper.

Bangladesh's sixth-wicket pair came together at 53 for 5 in the tenth over, and walked off together at the end of the innings with unbeaten 40s to their name. That both went at strike rates in the 120s, and both struggled to find the boundary for long stretches - including a barren spell of 21 balls - indicated both the excellence of Sri Lanka's defensive bowling, particularly that of Chameera whose yorkers achieved a rare level of precision in overs 18 and 20, and the two-paced nature of this Abu Dhabi surface.

Shamim hit the only six of Bangladesh's innings, a pick-up shot over midwicket off Matheesha Pathirana in the 19th over, and that shot and Pathirana's figures - 0 for 42 in four overs - indicated that batters could feed off pace on the ball in these conditions.

Both these teams have had well-documented issues with their T20I scoring rates in recent years, but Sri Lanka have been trendsetters in this format in previous eras. And Nissanka and Mishara showed that that spark might still endure.

Off just the fourth ball of his innings, Nissanka played what was unarguably the shot of the match up to that point, a resounding pulled six, well in front of square, off Mustafizur Rahman. And after Mustafizur hit back by nicking off Kusal Mendis, Nissanka and Mishara continued to pepper the boundary in a way Bangladesh had struggled to do throughout their innings.

This was partly down to Bangladesh bowling short balls far more frequently than Sri Lanka had, but Mishara also dispatched them with an easy, stand-and-deliver power that Bangladesh cricket has traditionally struggled to produce. None of this may have come to pass, however, had Mahedi held on to a chance at mid-on when Shoriful Islam got a short ball to get big on Mishara; he was batting on 1 off 7 at that point, and the pitch was still looking two-paced.

That spilled chance seemingly transformed the conditions too, with Mishara spanking the luckless Shoriful for 6, 4, 4 off the last three balls of the over. Nissanka, at the other end, sashayed this way and that to manipulate length and line, and timed the ball with a fluency that no one else from either side matched.

These two put on 95 in just 52 balls, and Sri Lanka could have finished things off even quicker, but they lost 3 for 18 in a 17-ball spell late in the game when they had the result all but sewn up.
