we saw SHubman Gill failed in the first innings. Indian captain was dismissed after scoring just 16 runs from 44 balls. India lost their third wicket for 107 runs. Although Gill could not bat well, KL rahul is batting very carefully today. Rahul is staying at the crease after scoring 50 runs.
It is difficult for India to take the lead in this match. However if Rahul and Rishab pant can play a big innings, india can take the lead. Apart from this, Jadeja, Nitish Reddy and Washington Sundor are capable of batting well. But their batting is a bit erratic. So if India loses any more wickets before scoring 200 runs, it is probably not possible for them to take the lead.
At the end of the first day , India managed to score 145 runs for the loss of 3 wickets. We have not seen any better batting from experienced players like Jaiswal and Gill. These two players managed to score 13 and 16 runs respectively. Apart from this , Karun nair managed to score 40 runs.
You are right that Rishab pant and Rahul will definitely have to play big innings if India wants to take the lead. Even though Jadeja and Nitish have the ability to play big innings, it is quite difficult to survive for a long time and play big innings on this pitch. It is not a batting friendly pitch. That is why India's future now largely depends on the innings of Pant and Rahul
