Ohh interesting. I have myself never played with a pink ball. Mostly played with the red ball only. This means reverse swing won't be a big wild card in the next match which means line and length will be the most important criteria therefore India will surely come down with the best pacers. Bumrah, Ishant and Siraj will be the obvious choices and the way Ashwin is batting, I think probable XI would have Axar, Ashwin and 3 pacers.
I have never played with a leather ball, so you are better in that regard.

For the third match I would prefer Umesh along with Jasprit and Ishant. Siraj looks like an overhyped player for me and I believe that he is in the squad only because of nepotism. If it was based purely on merit, then there were at least 2-3 other pace bowlers out there who had a better chance of getting selected. Kohli obviously is going to favor Saini and Siraj, since they are RCB players.
