If Zampa (2/24) operated with precision in the middle overs, Cummins (3/29) claimed three wickets off consecutive deliveries at the back end, as Australia restricted Bangladesh to 140/8 after Mitchell Marsh opted to bowl first in the rain-interrupted match.
Veteran opener David Warner (53 not out off 35 balls) then hit a scintillating fifty, an innings that was studded with five boundaries and three sixes.
