So results suggest Agarkar performed best against Aussies in ODI format. Possible reason Australia is weaker against incoming delivery as their batsmen are strong in cut and pull shot which is dangerous against incoming delivery. Poor chap he is the fastest bowler we have barring Munaf. This shows bowling strength of India in any.
