Sehwag, who made his first-class debut as a bowler who was a handy bat lower down the order, was moved to the top by skipper Sourav Ganguly at Lord's in 2002 to find a place for him in the side as he could not have fitted in the middle-order.
This reluctant change came about after he became the 11th Indian to score a hundred on debut batting in the middle-order against South Africa in Bloemfontein in 2001.
In his first Test as an opener, Sehwag struck a belligerent 84 and he came to stay as an opener, though he kept saying that he would prefer to bat in the middle-order despite his resounding success as an opener.
He revolutionised the game with his approach as an opener, amassing runs at a frenetic pace. His strike rate of 82.45 is the best for any batsman who has aggregated 2000-plus runs.
