Sydney: A historic series triumph already sealed, the Indian women's cricket team faltered in its quest for a clean-sweep as it went down by 15 runs to Australia in the third and final Twenty20 International following a spectacular batting collapse here today.

Chasing a victory target of 137, the Indians, who pocketed the series after winning the first two games, were comfortably placed at 94 for 3 in 13.3 overs before a middle-order collapse led them to end at 121 for 8 at the SCG.
