MS Dhoni smiles at you from a billboard as you step out of the Birsa Munda Airport in the quaint industrial town of Ranchi. The Indian One-Day International captain has reasons to smile about, besides the obvious performance benefits his choice of engine oil seemingly gives him. After dilly-dallying for a year, he appears to have seen merits of an elevation to No. 4 in the batting order. Instant validation came in Mohali via a match-winning 91-ball 80, which, along with another Virat Kohli hundred, gave the hosts a 2-1 lead in the five-match series. Now with his own batting concerns secured, at least for the immediate future, Dhoni will look to wrap the series up in well-known climes of his domicile.
