Debutant pacer Mohammed Shami devastating reverse swing deliveries helped him claim maiden five-wicket haul and help India beat West Indies by an innings and 51 runs in their first Test at Eden Gardens on Friday.
Shami bolwed 13.1 overs and gave away 47 runs to complete five-wicket haul, while spinner Ashwin scalped three-wicket in 19 overs.
Shami also claimed four wickets in first innings in 17 overs making it 9 for 118 runs in the debut match.
Earlier at tea break, team India tightened their grip in the first Test by reducing the West Indies to 112/3 as they were 107 runs behind India's first innings score of 453.
Ashwin made this Test a memorable one for him by cracking his second Test century and then grabbing three wickets.
The visitors were bundled out for a below par score of 168 in the second innings as India clinch the first Test match with two days to spare when Shami uprooted the middle stump of Cottrell in the 55th over.
Shami’s five wickets include Samuels, Ramdin, Sammy, Shillingford and Cottell.
Shivnarine Chanderpaul fought hard to remain not out at 31 off 60 balls but failed to save his side.
Ashwin removed Kieran Powell just before tea break in the 30.4 over, he scored 36 off 83 balls and smashed five boundaries.
Powell shared a 68-run stand with Darren Bravo for the second wicket.
After Powell, Mohammed Shami scalped Marlon Samuels LBW in the 31.6 over. He scored mere four runs off five balls to leave Windies struggling at 110/3 at this stage of the game.
At start, Indian pacer Bhuvneshwar Kumar struck early in the innings to claim the wicket of West Indies opening batsman Chris Gayle.
Gayle scored quick-fire 33 runs off 35 balls and smashed seven boundaries before being caught by Virat Kohli at point when he tried to pull an outside off ball.
Windies were 33/1 in 9.6 overs at this stage of the game.
Till Lunch, Debutant Rohit Sharma missed his maiden double century while R Ashwin smashed his second century to help India extended their lead to 219 runs against West Indies.
Indians were bowled out for 453 at Lunch on Day 3 by the visiting West Indies side.
Rohit and Ashwin shared a record stand of 280-run for the seventh wicket to boost India.
Sharma scored 177 off 301 balls and Ashwin made 124 runs off 210 balls.
For West Indies, Shane Shillingford was the most successful bowler as he claimed his fifth five-wicket haul. His figures read 6 for 167 in 55 overs.
Resuming at score of 354/6 on Day 3, India added another 99 runs and lost four wickets before lunch.
Sharma added 50 runs while Ashwin scored another 32 runs before he was bowled by Shillingford.
Centurion Rohit Sharma falls to another umpiring blunder when he was adjudged LBW off Permaul in the 124th over.
Sharma padded a straighter one on the offstump from leftarm spinner Permaul to be adjudged lbw by umpire Richard Kettleborough.
The West Indies bolwers pressed hard after Sharma's dismissal as India lost last four wickets for just 17 runs.
Sharma also became the second Indian after Shikhar Dhawan to score a 150 on debut.
Ashwin got to his second century with an elegant cover drive to Tino Best in the fourth over of the day.
Rohit and Ashwin surpassed the Indian highest seventh wicket partnership of 259 runs between VVS Laxman (143 not out) and MS Dhoni's (132 not out) vs South Africa in February 2010 at the same venue.
The Sharma-Ashwin partnership was the third highest in the all-time record for this wicket.
