Rohit Sharma's form is the only shortcoming in India's victories in the first two ODIs against injury-hit South Africa, but his opening partner Shikhar Dhawan is confident that the Mumbaikar is just a knock away from finding his groove in the six-match ODI series. Speaking to reporters on the eve of the third ODI at Newlands here, Dhawan said Rohit, who has so far scored just 35 runs in two innings, is timing the ball well and a good knock is not far away.
