It was Iyer's half-century and useful contributions from Deepak Hooda (38 off 25 balls) and stand-in skipper Hardik Pandya's (28 off 16 balls) cameo that propelled India to 188 for 7 in 20 overs after being put in to bat.
Then, Pandya handed the new ball to Axar Patel (3-1-15-3), who quickly removed makeshift opener Jason Holder (0), Shamarah Brooks (13) and Devon Thomas (10) with three arm balls on a track where balls stopped and gripped off the surface.
West Indies were all out for 100 runs inside 16 overs as one of the most lopsided T20I bilateral series came to an end even though India won't be complaining having ticked most of the boxes.
As It HappenedOnce Kuldeep Yadav (4-1-12-3) caught rival skipper Nicholas Pooran (3) plumb in-front with a flighted delivery, there was no way that the West Indies could have made a comeback on a track which wasn't easy for batting.
