India fought back from a precarious 2/3 — the lowest score at which the 3rd wicket has fallen from which a team has gone on to win an ODI — to beat Australia by 6 wickets and begin their World Cup campaign with a victory. KL Rahul scored 97 not out and Virat Kohli 85. Earlier, Ravindra Jadeja took 3/28 as Australia tumbled from 110/2 to 199 all out.
