Marco Jansen produced a devastating exhibition of pace and bounce to seize control of the second Test for South Africa on Day 3, finishing with a six-wicket haul as India were bundled out for 201 in 83.5 overs at the Barsapara Stadium here.

South Africa, enforcing their dominance, moved to 26 for no loss at stumps in their second innings, stretching their overall lead to a commanding 314 runs.

Jansen, who repeatedly extracted steep lift even as the surface slowed, broke India's resistance at crucial intervals and ran through the lower order with the second new ball. His spell after lunch dismantled India's remaining hopes, beginning with the dismissal of Rishabh Pant for 7 when the left-arm quick induced a reckless edge to the keeper.

Nitish Reddy fell to a vicious lifter taken brilliantly by Aiden Markram at slip, before Jansen removed Ravindra Jadeja on review, the ball brushing both shoulder and bat.

India, who had resumed at 102 for 4 after tea, slid rapidly as the pacer kept pounding the middle-and-off channel. Jansen's burst included the wickets of Sai Sudharsan (25), Dhruv Jurel (0), Jadeja (6), Kuldeep Yadav (19) and finally Jasprit Bumrah (5), whom he dismissed with another well-directed short ball to complete his six-for. Markram, at second slip, claimed five catches in a superb supporting effort.

Amid the collapse, Washington Sundar and Kuldeep Yadav mounted a stubborn eighth-wicket stand worth 72 runs off 208 balls.

Washington struck a clean six off Harmer and reached 48 before edging to slip, while Kuldeep batted 134 balls for a determined 19. Their resistance helped India reach 174 for 7 at lunch and 194 for 9 at drinks, before Jansen wrapped up the innings.

South Africa responded confidently with the bat. Rickelton punched the first ball of the innings for four, and Markram survived a tough chance at slip off Bumrah before driving Siraj through extra cover. Bad light halted play after 8 overs, with the visitors comfortably placed at 26 for 0.

With a 314-run cushion, ten wickets in hand, and momentum firmly on their side, South Africa enter Day 4 poised to dictate terms, while India face a daunting battle merely to stay afloat in the contest.
