A magnificent half century from Steve Smith led Australia to 132/1 in 25 overs after they lost David Warner early in the innings. Smith currently on 66 was ably supported by Aaron Finch who was batting on 47. David Warner started quickly hitting a four and a six but got a leading edge to a ball by Umesh Yadav giving a simple catch to Virat Kohli. Earlier, Australian captain Michael Clarke won the toss and elected to bat first against India in the second semifinal of the cricket World Cup at the SCG, here today. Both India and Australia have fielded unchanged sides.
