India have got little chance to get back into the game and hope for a draw. Australia team have already scored 123/4 which for India is good, but the lead is already close to 300 runs. With Labuschagne, Green, Alex Carey, Cummins left behind surely we can expect another 100 runs from Australia. If things go well Australia could set a target of 450+ runs for sure. In such situation it'll really hard for India to chase, but Australia have the power packed bowling lineup that could defend. Also the highest fourth innings run chase in the history of test cricket is 418 runs.
Anything below 400 would make the match interesting. Australia has a lead of 296 now, and they still need another 104 runs to reach that point. And it is not going to be easy. The pitch is behaving a bit differently in the past two days, when compared to the first day. But this lead would have been much bigger if not for the lack of discipline from the Australian bowlers. Pat Cummins got his wickets annulled a total of 3 times, after he overstepped the line. And then a lot of easy catches were dropped. Anyway, Australia is firmly in command here and they should be able to win this match.
