The West Indies are facing a heavy defeat after being dismissed for just 243 and being asked to follow on in reply to India's massive first-innings total of 566/8.
Resuming on 31/1 in the morning, it did not take long for the visitors to start making further inroads – though surprisingly it was fast bowlers Mohammed Shami and Umesh Yadav who proved to be India's trump cards on the day.
Amit Mishra bagged a couple of wickets as well, but inbetween them Shami and Yadav picked up seven scalps, as the Windies' resistance crumbled before and after lunch.
Shami tore the heart out of the home side's top order, dismissing Darren Bravo, Marlon Samuels and Jermaine Blackwood in quick succession – all caught behind by Wriddhiman Saha – while Yadav made further inroads later in the day, accounting for Roston Chase, Jason Holder and Carlos Braithwaite.
Kraigg Brathwaite's resolute 74 at the top of the order was the stand-out performance for the Windies, while Shane Dowrich also impressed with an unbeaten 57 as he put on 69 runs for the eighth wicket with Holder, who made 36.
Still enjoying a lead of 323 runs, India did not hesitate to send the West Indies back in, and that decision paid off almost immediately as Kraigg Braithwaite was trapped in front by Sharma in the first over of the innings.
Rajendra Chandrika and Darren Bravo saw out the remainder of the day's play without incident, ending the day on 21/1, but the hosts will need a minor miracle to avoid a heavy defeat in this Test, as they still find themselves trailing India's first innings total by 302 runs with two full days remaining.
