Sydney/IBNS: India captain Jasprit Bumrah and his trusted aide Mohammed Siraj throttled Australia in the first session on day two of the fifth and final Test at SCG in Sydney on Saturday.

Australia, who started off the day from 9-1, finished at 101-5 at lunch.

Bumrah, who picked Usman Khawaja on the last delivery of day one, removed Marnus Labuschagne early on day two.

Young batter Sam Konstas, who resumed his attack after seeing off some balls patiently, was caught in the slip cordon by KL Rahul bowled by Siraj for 23 from 38 balls.

Siraj drew more blood by dismissing in-form Travis Head (four runs) in the same over hurting Australia badly.

At the stroke of lunch, Prasidh Krishna brought India back to the game just when veteran Steven Smith and Beau Webster were on a roll.

Smith, who was set at 33, was caught in the slips as the tourists put up a promising bowling performance after scoring only 185 in the first innings.
