Ind vs Aus: Karthik explains why Dhoni struggled to run towards the end

Dinesh Karthik opened up on why Dhoni struggled to run towards the end in the second ODI against Australia. He said, "It was a very hot day. Everybody tried to have as many liquids as you could but still he was going through a lot of cramps. The fact that he was batting for a long, long time didn't help either. And with me being there, I run a lot. I run twos and threes and pushed him. So it was that much more harder for him. I think next time we play together, he'll prefer somebody else there who can hit a boundary or two. It was good, batting with him after a long time and it felt good."
