Rohit became the first batsman in world cricket to smash four T20 centuries in global cricket and also overtook Virat Kohli to become the highest run-scorer for India in the format. He scored a historic fourth hundred, also creating many other records in the process.
India put up a massive 195 for 2 and restricted West Indies to 124 for 9 to gain an unassailable 2-0 lead ahead of the third and final match of the series in Chennai.
With 2203 runs in 86 T20Is at an average of 33.89 and four tons, Rohit is just 68 runs behind New Zealand's Martin Guptill, who heads the all-time list with 2271 runs in 75 matches.
Rohit, who was lucky to see his shot brush Allen's fingers on 71, reached his century by scooping Brathwaite to the fine-leg rope in the final over, which produced 20 runs. He took a quick reflex catch which dismissed Darren Bravo off Yadav.
Kieron Pollard almost collided with Jasprit Bumrah while the latter was completing a caught and bowled chance. You don't have to make too many changes to your game because you already have shared the dressing room with global players, he said."When you come into the Indian team, by then you had already learned professionalism and know how to correct your mistakes".
Rohit now is the leading run-scorer for India in T20Is as he overtook Virat Kohli.
Dhawan made a brisk 43 but found himself playing second fiddle to the rampaging Rohit in their 123-run stand for the opening partnership.
For the hapless Windies, Fanian Allen returned best figures of 1/33 as all the bowlers were taken to the cleaners by Rohit.
After Dhawan's departure, Rishabh Pant too didn't last long but KL Rahul provided Rohit the requisite support with a busy 26 not out off 14 balls. There was no stopping the pair from there on as India raced to 83/0 at the halfway stage with both batsmen looking good for big scores. "I had more responsibility today as I was bowling with the new ball". Dhawan was dropped on 28 by Keemo Paul at the midwicket boundary off Brathwaite.
The openers will be keen to get some runs under their belt in this format as Darwan especially has been struggling in T20s of late so there is pressure on the top order to get them off to a better start in this game whether they set a total or chase.
