India and Australia would lock horns in the second T20I of the three-match series, on Friday, at the Melbourne Cricket Ground (MCG). The Virat Kohli-led India lost the opening encounter by 4 runs and are trailing 0-1. Aussies, on the other hand, know a victory would help them seal the series. Here we look at key battles and players that could determine the tie. Kuldeep Yadav has been in prime form this year. He is India's leading wicket-taker in 2018. He has a total of 19 scalps in T20Is this year. Kuldeep was excellent in the first match in Brisbane and got the wickets of well set Chris Lynn and Aaron Finch. His wrist spin will be crucial for India's chances in this match. Chris Lynn set the tempo for Australia in the first T20I. The aggressive right-handed batsman hit a whirlwind knock of 37 off just 20 deliveries. His 4 towering sixes was a pleasant sight. Lynn has the potential to do well and lay the foundation for the Aussies. His approach against the pacers will be key in getting the quick runs. Virat Kohli was forced to rush against leg-spinner Adam Zampa in the first T20I and ended up throwing his wicket. Zampa dominated with his leg-breaks and picked two crucial wickets. In the ODI series against England, Kohli got into trouble against Adil Rashid, and now Zampa could do the same. Australia will be keen to bring on Zampa just when Kohli comes in. Jasprit Bumrah will be keen to get Aaron Finch into trouble. He almost had his wicket early in the first match. Finch then responded with two boundaries in the same over. JB will not be willing to bowl too full against Finch, knowing his prowess in driving the ball. Finch would be targeted by JB with the in-swinging ball.
