India's pacemen brought them back into the second Test against West Indies, after they suffered a batting collapse on the first day here on Tuesday.
Ishant Sharma, Praveen Kumar, and Test newcomer Abhimanyu Mithun all collected a wicket apiece to leave West Indies in tatters on 30 for three, in reply to India's first innings total of 201 at the close.
Sharma made the breakthrough, when he had Adrian Barath caught at gully for three in the fourth over, and next over, Praveen Kumar had Lendl Simmons caught behind for two, leaving West Indies five for two.
Darren Bravo joined Ramnaresh Sarwan, and stemmed the fall of wickets before the left-hander was caught behind for nine from the penultimate ball of the day from Mithun.
Earlier, India were given further cause to usher in the use of the umpire decision review system.
Left-hander Suresh Raina was dubiously dismissed for 53, triggering a batting collapse that saw the Indians lose their last five wickets for 34 runs in the space of 55 balls.
Raina was caught at forward short leg off West Indies leg-spinner Devendra Bishoo for 53, following a 117-run, fifth-wicket stand with V.V.S. Laxman, whose 85 was the top score, and helped to rescue the visitors from a perilous 38 for four before lunch.
The left-hander was clearly upset by the decision from Pakistani umpire Asad Rauf, which television replays suggested was highly dubious, dropping his bat, staring in anger at the official, and swinging his bat in disgust.
Fidel Edwards then ran through the lower half of India's batting, removing their captain Mahendra Singh Dhoni for two, Harbhajan Singh for five, and Mithun for a duck, finishing with three for 56 from 19 overs.
Ravi Rampaul was the pick of the West Indies bowlers, with three for 38 from 16 overs, and Bishoo snared three for 46 from 14 overs.
Laxman reached his 50 from 75 balls, glancing Edwards to the fine leg boundary for his eight four, and Raina reached the landmark from 90 deliveries, paddling Bishoo to long-leg for a single.
The two batsmen ensured India did not lose a wicket between lunch and tea, after the top order were given a real going over by Rampaul, who exploited helpful conditions in taking three of the wickets to fall.
India suffered an early setback, when left-handed opener Abhinav Mukund was caught at gully for one off Rampaul in the second over of the day.
The Indians ran into further trouble, when Rahul Dravid, a century-maker in the first Test, was caught behind for five, playing defensively forward to a delivery from West Indies captain Darren Sammy.
Murali Vijay was fortunate on four, when he sliced a drive at a delivery from Sammy, and Bishoo failed to hold onto a low, diving chance at backward point.
India reached 13 for two from 14 overs after the first hour, failing to strike a boundary, but Laxman brought India their first four, when he pulled Sammy through wide mid-on.
But the Indians were jolted, when Rampaul had opener Murali Vijay caught behind down the leg side for a painstaking 11, and two deliveries later, Virat Kohli caught at second slip for a duck, fending a sharply rising delivery.
India are looking to wrap up their second straight Test series victory over West Indies in the Caribbean.
They will also be looking to create a piece of history by becoming the first Indian side to win a Test and One-day International series in the Caribbean - but they will also have to overcome their poor history here.
Mahendra Singh Dhoni's team still have cause for optimism though - following a 10-wicket defeat for Sourav Ganguly's side nine years ago, West Indies have lost six of the next eight Tests they have played at this venue.
