A confident appeal for leg before wicket against Smith, who is struck on the pads by the incoming delivery from Siraj.
Siraj is pretty confident but the umpire is not interested. India have one review but Rohit Sharma is not keen on the DRS.
There was a clear inside edge and the Indians did well not to take the review.
Cummins keeps the scoreboard ticking along as he taps Siraj on the off-side for one.
Smith flicks the pacer for an easy run to deep square leg to take his score to 96.
Australia are well-placed on 371/6 in 100 overs, having scored 60 runs in 14 overs bowled in the opening hour.
