Pacer Anderson Phillip back into the attack. Jaiswal drills an overpitched delivery straight back past the bowler for a four and clips the next for one.
Sudharsan takes a single in the gap at midwicket before Phillip bowls a beauty to beat Jaiswal on the outside edge last ball.
In the next over, Sudharsan crashes Pierre in the gap through the covers for a four to bring up his fifty in some style, from 87 balls.
This is only Sudharsan's second half-century in Tests and this could help him silence his critics.
At the drinks break, India are 175/1 in 45 overs, having scored 81 runs in 17 overs in the first hour of the second session.
