Bowlers dominated on the opening day of the first Test between Bangladesh and Australia as 13 wickets fell in a match that remains in the balance in Dhaka.
Pat Cummins, Nathan Lyon and Ashton Agar took three wickets apiece as the Baggy Green skittled their hosts for 260 but Bangladesh hit back in the final nine overs of the day to limit the tourists to 18-3 at stumps.
Home captain Mushfiqur Rahim won the toss and elected to bat but that decision backfired as seamer Cummins grabbed three wickets inside eight balls, claiming the scalps of Soumya Sarkar, Imrul Kayes and Sabbir Rahman - for a golden duck - to leave them struggling on 10-3.
Shakib Al Hasan and Tamim Iqbal responded with half-centuries to record a stand of 155 before Glenn Maxwell earned the decisive wicket of opener Tamim, with a 35-minute rain delay aiding spinners Lyon and Agar to combine to dismantle the lower order for just 90 runs.
Lyon's haul took him to 250 Test scalps, clear of the late, great Richie Benaud, and he now sits eighth on Australia's all-time list.
Mushifiqur followed suit in deploying off-spinner Mehedi Hasan from the start of the Australia innings and was rewarded with the wicket of David Warner for eight runs.
Usman Khawaja was run out by Sarkar for just a single before Shakib avenged his dismissal by Lyon by trapping the nightwatchman for his side's third wicket in the space of 10 balls to finish an entertaining first day.
