Ajinkya Rahane will hold the key for India in the first session, at least, while South Africa will want to put India's first innings to bed as soon as possible when both teams step onto the Feroz Shah Kotla for Day 2 of the fourth Test match in Delhi.

Rahane was one major bright spot for India on the opening day of this Test match, with the right-hander scoring 89 of his team's total of 231/7 at the close of play.

Two batsmen looked comfortable on the opening day, one of them was obviously Rahane, with the other being Virat Kohli, who was dismissed in unfortunate circumstances.

With Rahane having R Ashwin for company, the duo will want to bat for as long as possible on Day 2 and with it take India's score close to 300 if not beyond it.

"If we bat out the first session tomorrow, it will be a good effort from us," India batting coach Sanjay Bangar said. "One positive thing that we have seen in the recent times is the way the lower order has been contributing with the bat.

"Earlier we had this issue where our lower order wasn't scoring runs. But the improvement that they have shown in Sri Lanka and even here, scoring crucial runs, is a positive thing for us."

South Africa will want to shut India out within 250, and they will bank on the new ball that is available to do just that.

Morne Morkel and Kyle Abbott bowled quite well with the shiny red cherry on day one morning, and with lower-order batsmen now at the crease along with Rahane, the two fast bowlers will fancy taking those three wickets quickly.

"I think the game is still even," South Africa off-spinner Dane Piedt, who took four wickets on the opening day, said. "It depends on how we bowl [on day two] morning, but if we can keep them under 250, it should be a good score.

"I think the odd ball is still skidding on, and we are getting the odd one to bounce. It's been a good wicket for everyone."
