Ranchi: An exultant India coach Ravi Shastri yesterday said Rohit Sharma has shown himself to be of different class in the newly-acquired role of a Test opener, acclimatising exceptionally well to the challenges posed by the position. India wrapped a 3-0 whitewash of South Africa by winning the third and final Test by an innings and 202 runs on the morning of Day Four here.

"Ajinkya Rahane was always there in the middle order, he only needed to rediscover, which he did himself. Rohit is different class. As an opener he needed to have a different mindset, he acclimatised. It was a difficult pitch to start with but usne jhela," Shastri told official broadcaster 'Star Sports' at the end of the match. "He has it in him to be unfazed by difficult conditions. What he has done in this series is tremendous," he added.

Shastri lauded the mindset of the team, which he said, is never perturbed by the conditions it encounters whether at home or abroad.
