DARWIN, Australia — Bangladesh ended the opening day of the first Test against Australia in a strong position after dismissing the hosts for 198 and reaching 96 for 1 by stumps at Marrara Cricket Ground on Thursday. Australia won the toss and elected to bat first, but Bangladesh’s seamers repeatedly found the right areas and eventually claimed all 10 Australian wickets. Hasan Mahmud was the standout performer with career-best figures of 6 for 55.
