During the first innings, Ashwin booked his 33rd five-wicket haul surpassing England legend James Anderson, making him the active bowler with most fifers.
Ashwin's performance equaled Rangana Herath's score of 34 five-wicket hauls in Tests, putting him fifth overall and just one behind Anil Kumble's record.
Ashwin's bowling figure of 12 for 131 marks his best match returns in an away Test, the best Indian bowler achievement in a West Indies test and the best by a spinner overall.
