Mohammed Siraj was menacing during his first spell, grabbing two wickets with perfectly pitched outswingers before Prasidh Krishna sent back in-form Steve Smith as India reduced Australia to 101 for 5 at lunch on the second day of the fifth Test here on Saturday.

Smith (33) was involved in a nice little 57-run stand for the fifth wicket with Beau Webster after Siraj had rocked the top-order with two wickets in four balls to reduce the hosts to 39 for 4.
