India rode on Ravichandran Ashwin's memorable performance of 7/83 to outplay the West Indies by an innings and 92 runs, their biggest win outside Asia, in a lopsided first cricket Test to take a 1-0 lead in the four-match series here.
Having started the day on 21-1, following on and still trailing India by 302 runs, West Indies were under immense pressure from the start. After losing Darren Bravo in the first over of the day, the tone was set for their second innings, and the hosts never really recovered.
Ashwin produced an off-spin bowling masterclass and triggered a second-innings slide that saw the hosts collapse from 88/2 to 132/8 on the fourth and penultimate day.
A defiant ninth-wicket stand of 95, West Indies' highest in the game, between Carlos Brathwaite (51 not out) and Devendra Bishoo (45) delayed the inevitable before Ashwin came back to seal the issue by bowling the hosts out for 231.
This was also the Tamil Nadu spinner's first five-wicket haul outside the Asian continent.
India bowled out the West Indies for 243 in their first innings, having amassed 566 for eight declared after opting to bat. Forced to follow-on after conceding a massive lead of 323, the hosts failed to cope up with intense pressure created by Ashwin and Co on a pitch that offered assistance to slow bowlers.
At the Sir Vivian Richards Stadium, the visitors shot out the hosts in three hours over the post lunch and tea session to finish their two innings at 243 and 231.
After tea, Brathwaite reached his third Test fifty, but the rest of the innings folded in just over 40 minutes. Bishoo hit straight to midwicket off Ashwin in the 78th over, and three balls later bowled Shannon Gabriel (4) to wrap up the proceedings with a day to spare.
Post lunch, it was an extended session of play which proved enough for India to force a win. But first they had to break through the 67-run partnership between Rajendra Chandrika (31) and Marlon Samuels (50). The two batsmen began again in the same vein, trying to play for time, and in doing so, the latter crossed the 50-mark off 74 balls raising hopes of a fight back.
But it was short-lived as Chandrika had a faint inside-edge off Ashwin in the 36th over, judged accurately by the umpire and caught on the third attempt by Wriddhiman Saha.
It started the slide for West Indies and the off-spinner barged into the opening he had found.
In the very next over, he removed Jermaine Blackwood (0) for a second duck in the match, with skipper Virat Kohli holding a magnificent diving catch at midwicket to aid in the dismissal.
Then came the best moment for Ashwin, as a beautiful delivery beat Samuels' straight bat and knocked back his off-stump in the 42nd over.
Virat Kohli's side showed great professionalism in all departments, with the India skipper recording his maiden double century and all-rounder Ashwin supporting with 113. It was the second time Ashwin has hit a century and taken five wickets in an innings in the same match.
West Indies will look to improve on their disappointing performance in the second test which starts July 30 in Jamaica.
