Ashwin justified his top billing in ICC Test bowlers' ranking with figures of 5 for 60 in 24.3 overs to decimate West Indies for a lowly 150 in 64.3 overs with Ravindra Jadeja (3/26 in 14 overs) beautifully complementing him to make life miserable for the home team batters.
Making full use of the slow two-paced track that also offered turn and bounce, Ashwin had reasons to be chuffed as he became third Indian bowler after Anil Kumble (956 wickets) and Harbhajan Singh (711) to complete 700 scalps across formats in international cricket.
He also achieved the distinction of being first Indian bowler to dismiss father and son when he got rid of Shivnarine Chanderpaul's son Tagenarine, having dismissed the father on his Test debut in 2011.
Save debutant left-hander Alick Athanaze (47 off 99), who batted responsibly till his dismissal, none of the Caribbean batters had the technique to survive on a slow turner as none of them could even cross 20-run mark.
Ashwin varied his pace, bowling a few sliders and pushing some other deliveries across to right handers while effectively using the drift to bowl conventional off-breaks to left-handers.
The tireless Mohammed Siraj (12-2-25-1) also deserves a lot of credit as he bowled a beautiful fuller length during first session, changed his tactic to use a lot more bouncers post-lunch to hurry the batters on a slow track.
One such delivery accounted for Jason Holder, who took the bait and was holed out at square leg boundary for the fielder stationed for that mistimed pull-shot.
Siraj was also brilliant on the field as his diving catch at mid-off to dismiss Jermaine Blackwood off Jadeja's bowling was top notch effort.
The pressure created by the pace duo did reap dividends as Ashwin slowed the pace of his deliveries, used the available drift to a good advantage to make life uncomfortable for the two openers.
There was a nice loop and he did challenge both inside and outside edge during the second hour.
Tagenarine's stance and trigger shuffle from leg to off-stump does have an uncanny resemblance with his illustrious father Shivnarine although he is slightly more side-on compared to his 'Old Man'.
Sensing his shuffle, Ashwin got one to hang in the air and drift into the southpaw, who played inside the line only to find it beat his outside edge after pitching and there was a death rattle.
