Kohli was unstoppable in the second Test. He led the way for the side.
After the match, Kohli said he enjoys scoring runs.
"I'm just happy to be where I am. Putting the team in a commanding position is the only thing I strive for," Kohli said.
"Of course I enjoy scoring runs, but if they come in a winning cause, nothing like it."
Kohli needs two rating points to surpass Smith
Kohli will be eyeing to score more runs in the third Test against South Africa. He has 936 rating points at the moment and is a solitary point away from leader Smith, who sits at the top (937). Kohli could get past Smith next.
Smith and Kohli
The battle for the number one spot will continue
Kohli is likely to get past Smith soon. The next assignment for Team India is the two-match Test series against Bangladesh next month.
That's when the Indian skipper can gain more prominence in the rankings.
However, Australia will be involved in a two-match Test series against Pakistan at home.
One can expect Smith to defy the visitors and challenge Kohli for the top spot.
