Bangladesh solve the middle-overs riddle

When Sri Lanka beat Bangladesh in Abu Dhabi last week, it boiled down to the middle overs. Chasing 140 at a time when no one seemed quite sure what constituted a good total in the Asia Cup, Sri Lanka emerged from the powerplay with the fluidity of a car merging back on to the motorway. They barely changing gears from their belligerent start, motoring on as if a punctuation mark in the passage of play had never happened. The spread field held little meaning as they plundered 81 runs off the eight overs immediately following the easing of fielding restrictions. It remains, comfortably, the highest number of runs scored in that period all tournament.

A week on, and Bangladesh inserted Sri Lanka. They had not let victory over Afghanistan defending a total play with their heads, aware that as the tournament goes on, chasing appears to proffer a clear advantage. Two days earlier, Sri Lanka had chased down 170 against Afghanistan - the highest successful pursuit of the tournament and one that Bangladesh owe their continued involvement in this tournament to. They had no intention of doing Sri Lanka any return favours here in Dubai.

Sri Lanka may have been unbeaten this tournament, but all those wins came batting second. Even so, Pathum Nissanka and Kusal Mendis started brightly, scoring 36 in the first four overs - the highest off the bat for them this tournament - but with Bangladesh holding Mustafizur Rahman back until after the powerplay, they understood exactly when to start applying the strangle.

Nissanka had fallen to Taskin Ahmed by now, and with Mustafizur bearing down, they found merging into post-powerplay traffic trickier this time. The seventh produced just three runs; Mahedi Hasan's over that followed claimed the wicket of Mendis. He cleaned up Kamil Mishara in the next as Sri Lanka retreated into a shell they have not known in the middle overs this tournament, and one that offered them little protection.

Mustafizur wouldn't return until the 14th over, with Sri Lanka's run rate scarcely above seven; it took him just four balls to end Kusal Perera's run-a-ball innings. This time, in those same eight overs, Sri Lanka scored just 45 runs. Excluding matches involving Oman or UAE, it is the second lowest post-powerplay middle-overs effort of the tournament, bettered only by the chokehold India established on Pakistan in the phase that followed the first six overs. All this despite Sri Lanka being - by orders of magnitude - the most prolific side in overs 7-15, scoring at 8.12, with India a distant second at 7.68.

It was a passage of play Dasun Shanaka tried to right in an astonishing lower-order onslaught, hitting six sixes in an unbeaten 37-ball 64, but acknowledged had hurt Sri Lanka decisively in the end.

"We had that momentum going on at the start," he said at the press conference after. "But unfortunately we lost some momentum. Especially Fizz and Taskin bowled really well. We expected to score 180 but unfortunately we fell short. We fell 10-15 runs short."

That last remark can feel like the sort of catch-all cliché captains deploy post-match, primarily because any serious post-match analysis is yet to happen, and will take place behind closed doors rather than therapised to the media. But, in pursuit, Bangladesh knew those extra handful of runs were all that they really needed. Their own 7-15 over run rate is just a tick over seven. But having done their attacking in the first six, where they smashed 59, a number only India have bettered all tournament, that's all they required.

Anchoring is a much nicer gig chasing rather than setting a total, and especially if you are ahead of the rate. They scored 55 in the eight overs that followed. They hit a pair of fours and a pair of sixes. They lost a pair of wickets, but they had the luxury of hunkering down. They didn't need to outrun the bear, only the snail-like pace Sri Lanka had established in that phase of the innings. Ten runs ahead was all the margin they needed.

"While we were batting in that phase, [Towhid] Hridoy and I had a good partnership," Saif Hassan, who combined with Hridoy for all but three balls of that passage of play, said. "We had built our partnership knowing we were ahead in the game at that point."

From the vantage point other cricket nations have rather snootily opted to mount when viewing the new edge that Bangladesh-Sri Lanka contests have taken on, the perception is that this isn't a rivalry to be taken quite as seriously. That it's petty, overly emotional, and lacks a legitimate basis in cricket itself. In Dubai, though, Bangladesh shed all that with the clinical execution of a game plan they had brought to the game, one that aligned so well with their script that the fact that the chase went down to the penultimate delivery felt like a feature, not a bug.

Sri Lanka's caution in the face of Bangladesh's accuracy through the middle might have reflected a belief that the side they had reprieved just two days earlier could be reeled right back in on command.

But having regained control of their destiny, Bangladesh's attack right through the middle demonstrated a clear understanding of the format they were playing: incremental, unspectacular improvement in any facet of a T20 innings might be all that's required to turn defeat into victory.
