4th Test Day 2 LIVE: Australia Bring Up 450, Smith Nears Huge Milestone

India vs Australia 4th Test Day 2 LIVE Updates: Steve Smith cruised to a 34th Test century, and a second successive against India, with some fine stroke-play in the morning session of Day 2 of the 4th Test in Melbourne. On the other hand, Australia captain Pat Cummins fell just one run short of his own fifty. The duo combined to take Australia past the 400-run mark. India captain Rohit Sharma's confusing call to start with Mohammed Siraj before replacing him just one over later with Jasprit Bumrah baffles many.  Bumrah's three wickets on the opening day helped India make a comeback in the game, but Australia still managed to finish the day in a good position, thanks to fifties from Sam Konstas (60), Usman Khawaja (57), Marnus Labuschagne (72) and Steve Smith.
