UPDATE 3-Cricket-Australia power to one-day series win in India

* Australia take 4-2 series lead

* Bollinger fizzes with 5-35

* Opener Watson sets tone with 49 (Adds quotes)

GUWAHATI, India, Nov 8 (Reuters) - Left-arm seamer Doug Bollinger grabbed five for 35 to set up Australia's six-wicket victory over India in the sixth one-dayer on Sunday for an unassailable 4-2 lead in the seven-match series.

New ball bowler Bollinger dismissed Sachin Tendulkar (10) and Yuvraj Singh (6) off successive overs in his opening spell before claiming Mahendra Dhoni (24), Harbhajan Singh (zero) and Ravindra Jadeja for 57 to bowl out India for 170.

All-rounders Jadeja and Praveen Kumar (54 not out) struck fifties and shared in a 74-run stand for the eighth wicket to lift the hosts, who were tottering at 27 for five after choosing to bat first on a two-paced pitch.

In-form Shane Watson struck 49 but the world champions suffered a mini collapse when off-spinner Harbhajan Singh took Watson and Ricky Ponting (25) in quick succession.

Michael Hussey (35 not out) put on 53 for the fourth wicket with Cameron White (25) and 29 with Adam Voges (23 not out) to guide the team to victory in 41.5 overs.

Top-ranked Australia had five players sent back from the series with injuries.
