Guwahati (India) (AFP) - Pace spearhead Marco Jansen took six wickets as South Africa bundled out India for 201 on day three Monday with the hosts in grave danger of losing the second Test and the series.

Replying to South Africa’s 489, India were 288 behind in their first innings but the tourists did not enforce the follow-on and decided to bat again in Guwahati.

Jansen, a left-arm quick, claimed his fourth five-wicket Test haul before wrapping up the Indian innings with his sixth strike of the day.

After winning the first Test in the two-match series in Kolkata, South Africa are sniffing a first series win in India since Hansie Cronje’s team triumphed in 2000.

India are under pressure once more, having suffered their fourth defeat in six Tests at home in the first match.

India slumped to 122-7 despite Yashasvi Jaiswal’s 58 as wickets kept tumbling on what still seems like a good pitch to bat on.

Washington Sundar, who made 48, and fellow left-hander Kuldeep Yadav resisted in a partnership of 72 off 208 balls before off-spinner Simon Harmer struck to end Sundar’s defiance.

Jansen then dismissed Kuldeep for 19 and Jasprit Bumrah for two to pack India off in under three sessions.

Earlier, the left-handed Jaiswal lost overnight partner KL Rahul for 22 in the first hour of play before reaching his 13th Test half-century.

Jaiswal used the sweep to good effect and took on the bowlers, hitting seven fours and one six until his departure off Harmer.

Harmer had Sai Sudharsan caught at mid-wicket for 15 and Jansen removed Dhruv Jurel for a duck to further put India on the back foot at the first break.

Skipper Rishabh Pant fell caught behind for seven to Jansen soon after in the second session and the batting fell apart like nine pins.

Aiden Markram took a stunning catch as he ran from second slip to take a one-handed diving catch to his right to dismiss Nitish Kumar Reddy off Jansen. Reddy made 10.
