India will take on Australia in the 7th and last one-dayer at Mumbai today. As Australia have already clinched the series 4-2, the match will be of academic interest only. However a victory in this will be the ideal tonic for India before they lock horns with Srilanka in the longest format of the game from 16th November in Ahmedabad, but steady unseasonal rains are threatening to wash out the match.The rains, which started yesterday, did not allow the Indian team to have their match- practice session.All India Radio will broadcast the running commentary from 2 P.M. onwards. It will be available on Rajdhani and FM Gold channels.
