Sydney/IBNS: India's stand-in captain Jasprit Bumrah is set to be the prime rescuer for his team after the tourists were bundled out for 185 in another poor display of batting against Australia in the fifth and final Test of the Border Gavaskar Trophy in Sydney on Friday.

Bumrah picked his 31st wicket in the ongoing Test series in the form of Aussie opener Usman Khawaja, who was dismissed for just two on the last ball of the first day's play.

The day ended with Australia's scorecard reading 9-1 from three overs.

Bumrah, who was at the toss in absence of out-of-form Rohit Sharma, breathed energy into the beleaguered side with the lone wicket soon after the world's best bowler held a confrontation with two-match-old Aussie opener, Sam Konstas.

Konstas, who was charged by the Indian players including Bumrah after Khawaja's dismissal, will walk out to bat on Tuesday morning as he remained unbeaten at seven.

Prior to the wicket, Bumrah added vital 22 from 17 balls with the bat as a tailender to stretch India's innings to 185.

In a repetition of what went on throughout the Border Gavaskar Trophy for the tourists, India started off the final Test with disappointment with the bat even after captain Rohit Sharma rested himself in hope for a rebound at SCG.

After Bumrah won the coin toss and opted to bat first on a wicket which is almost covered in grass, the visitors lost early wickets in the form of KL Rahul (4) and Yashasvi Jaiswal (10).

Shubman Gill, who was looking settled in the middle, was caught in the slip by Steven Smith off Nathan Lyon in a staggering shot just at the stroke of lunch.

Gill, who replaced out-of-form Rohit, needlessly stepped out of the crease and edged Lyon's turner to Smith falling for 20.

Virat Kohli, the other senior Indian batter who is under the pump over poor show with bat, was dismissed poking an off-stump ball bowled by Scott Boland, who bagged four wickets for 31 runs.

The former captain, who had survived a dismissal threat earlier with the third umpire's decision, was sent packing for 17 from 69 balls.

Rishabh Pant, who headlined the Indian batting with a patient 40, suffered hits on his hand and head tackling fierce Aussie bowling but finally Boland tricked him with a short-ball that the southpaw mistimed and was caught by Pat Cummins in the inner circle.
