Rohit says Rayadu has solved mysteries of number 4

India's Rohit Sharma Monday said the 81-ball 100 by Ambati Rayudu will remove any doubts that he is the ideal number four in the run-up to next year's World Cup in England.

Rohit and Rayudu smashed hundreds to lay the ground for India's 224-run rout of the West Indies in the fourth and penultimate ODI at the Brabourne Stadium.

"I think (it's a) very important (knock). Hopefully he has solved all the mysteries of number 4. I guess till the World Cup, there won't be any talk of number 4," said Sharma in the post-match media conference.

Sharma led the way with his whirlwind innings of 162 and Rayudu played the ideal foil with a knock of 100, the two adding 211 runs to power India to an imposing 377 for five. West Indies were bowled out for 153 with rookie left-arm seamer Khaleel Ahmed grabbing three wickets.

"He (Rayudu) batted brilliantly because at that point a big partnership was needed and it was a perfect platform for him also to showcase what he's got. There was pressure, of course, losing top two batsmen and building a partnership was important. So it was a pressure innings and I thought he responded well to that situation."
