Border-Gavaskar Trophy Live Score: India took control of the proceedings
Debutant Nathan McSweeney (10) got a nip-backer and DRS ruled him leg before.
Usman Khawaja (8) just froze in his crease once Bumrah decided to square him up by coming round the wicket. Virat Kohli, who had earlier dropped Marnus Labuschagne ( 2 off 52 balls), didn’t make any mistake on this one.
But it was out of form Steven Smith (0), who got a very difficult first delivery that zoomed in and dipped catching him plumb in front.
Once Bumrah set the tone, debutant Harshit, with a bustling action, got one that pitched on middle stump, drawing Travis Head (11) forward before it deviated to dislodge the off-bail.
Australia were reeling at 31 for 4.
Labuschagne took 24 balls to get off the mark and also found himself at the receiving end of some heated words from an agitated Siraj.
The Indian then pitched one up to Mitchell Marsh and the resultant edge was brilliantly snapped by KL Rahul before ending Labuschagne’s 52-ball agony with an in-cutter.
Bumrah then came for his final spell of the day to remove the rival skipper as India took control of the proceedings.
