Mahendra Singh Dhoni has once again proved why cricket fans are right in calling the 'DRS' as 'Dhoni Review System'. In the fourth ODI, which India lost to South Africa in Johannesburg, Dhoni once again saved India and Virat Kohli from wasting a review with a perfect call. Dhoni has time and again proved that he has mastered the art of using the Decision Review System and this time as well, he was right on the mark even as Rohit Sharma was seen signalling Kohli to take the review. But a shake of the head from Dhoni was enough for the Indian skipper, and rightly so. Jasprit Bumrah bowled a peach of a delivery to Hashim Amla, beating him all ends up. Immediately, every Indian on the field appealed for a caught behind, including Dhoni, but the umpire shook his head. As the Indian fielders converged near Amla, Rohit was seen signalling Kohli to take the DRS, Dhoni with a wry smile on his face shook his head to say that there was no edge. Kohli did not take the DRS and the replays and Ultra-edge showed there was no edge whatsover.
