I would say that it was an intelligent decision to go with 4 full-time bowlers and one all rounder (Jadeja). India can get to 500 plus even with 6 batsmen and they don't need the 7th slot given to players such as Vihari. But as we saw during the first innings of the last test, Indian bowling struggled against experienced South African batsmen. Still, I would have liked Kuldeep in place of the other Yadav.
Umesh is a good bowler, but since this match is being played in India, on average around 70% of the overs will be bowled by the spinners (Ashwin / Jadeja). Therefore we have three bowlers to do 30% of the overs (Ishant, Umesh and Shami), and two bowlers (Ashwin and Jadeja) for the remaining 70% of the overs. I am assuming that it is another spin-friendly track.
South Africa using good amount of short balls against the Indians but both the batsmen handled them well.
And Rabada strikes again! End of Pujara's inning, big wicket for Proteas he was looking set.
