India must beat Sri Lanka by a bonus point in Hobart on Tuesday to have any hope of playing in the best-of-three match final series after their fourth defeat in seven matches in the tournament.

India put in another abject batting display and crashed to 104 for six in the 27th over in a match where they always looked to be struggling against the well-drilled Australians.
Tailender Ravi Ashwin topscored with 26 off 37 balls, while Sachin Tendulkar (14), Virender Sehwag (5) and skipper M.S. Dhoni (14) were all out cheaply.
