Both Rahul and Mayank were watchful and left anything that was on a length outside the off-stump. As the batters showed discipline against length, South African bowlers had to try different tactics which the openers targetted but with soft hands.
Mayank, in particular, looked solid with his hand-eye coordination to put the bad balls to the boundary. Debutant Marco Jensen did create a massive chance when he got the edge off Mayank's bat but Quinton de Kock couldn't grab it. Rahul was a bit more on the defense. Both Karnataka statemates had a good understanding as they ran well between the wickets.
India - 83/0 in 28 overs (Mayank Agarwal - 45*, KL Rahul - 29*)
