Ellyse Perry and Sophie Molineux have proved the Australian matchwinners with bat and ball as they inspired Royal Challengers Bangalore (RCB) to the Women's Premier League title in India.

Perry enhanced her claims to be the best player in the history of the women's game as she completed a week of scintillating performances by guiding RCB coolly to an eight-wicket victory in Sunday's final over her fellow luminary Meg Lanning's Delhi Capitals, thanks to a measured finishing knock of 35 not out.

But the Aussie who really silenced the home Delhi fans in the Arun Jaitley Stadium was Molineux, who earlier produced one dream over of spin, taking three wickets in four balls to devastate the Capitals' top-order and end Lanning's ambition of a final triumph for the second year running.

After winning the toss, Lanning, playing second fiddle to the big-hitting Shafali Verma, had powered Delhi to the ideal start, blitzing to 0-64 in just seven overs.

But Molineux (3-20) struck to get Verma (44) caught on the boundary by fellow Aussie Georgia Wareham, before delivering a dot ball and then bowling the dangerous pair of Jemimah Rodrigues and Alice Capsey in successive balls.

When Lanning then got snared lbw by another spinner, Shreyanka Patil for a run-a-ball 23, the heart was ripped from the Delhi innings as they crumbled from 4-74 to 113 all out off 18.3 overs. Shreyanka was outstanding with her 4-12.

Molineux also proved brilliant in the field, running out Radha Yadav with a direct hit, powering in a left-handed throw from point.

RCB's reply was a cautious affair with Perry taking it on herself to carefully steer the ship after captain Smriti Mandhana (31) and Sophie Devine (32) had been dismissed.

But the winning line always seemed to be under her control as Perry hit four boundaries in her 37-ball knock while Richa Ghosh was an able partner, finishing 17 not out off 14 balls after clubbing the winning boundary with still three balls left.
