One wicket. That is all Australia have managed in 14.2 overs since Bangladesh began their second innings, and already the tension at the ground is electric. Tanzid Hasan was gone for a duck in just the fifth delivery of the innings, bowled by a sharp Josh Hazlewood delivery that rattled the stumps before the crowd had barely settled.

At 4 for 1, the chase — or rather, the survival — was already in crisis. Yet Shadman Islam and Mominul Haque have refused to collapse. Shadman, unbeaten on 25 from 42 balls, is playing with a calm authority that belies the pressure bearing down on him. Mominul, Bangladesh's most experienced middle-order presence, is alongside him on 30 from 39 deliveries, striking at 76.

92. Together, they have guided Bangladesh to 57 for 1 at the interval — not comfortable, but no longer catastrophic. Australia's bowlers have been disciplined. Mitchell Starc has sent down four overs, conceding 15 runs without a wicket, while Hazlewood's three overs have cost just five runs for his solitary breakthrough — an economy rate of 1.

66 that tells its own story. Nathan Lyon, the off-spinner who has tormented subcontinent batters across two decades of Test cricket, has bowled five overs for 23 runs, so far without reward. The real question now is whether Shadman and Mominul can build a partnership long enough to force Australia into doubt.
