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.
If you compare batting of Aussie in both innings then Aussies are doing exactly what they have done in first innings. The difference is that in first innings Smith and Head came to rescue Australia. Smith and Head both are back in pavilion, if Aussies can find a pair that can contribute 100 or more runs then that will be enough for them. From India perspective they must try to bowl out Aussies before they set a target of 350.
