The Australians were impressed with their victory in the previous ODI with India and somehow took revenge for defeat in the previous T20.
CJ McKay, who took the Dhoni wicket, played a key role in this victory, and essentially put an end to India's hopes of winning the game, releasing their leader and their last hope for a big score.
McKay seems to be in good shape lately, has taken 4 wickets in the last two games against India and in the previous game he also put 11 runs on the Australian score. As the above statistics show, the line of 30 points looks a bit low for its performance. The player gets 1 points for each run, 10 points for each catch and 20 points for each wicket.
