It was for long the insurmountable peak for ODI batting, but one man might now have a template to score ODI double-centuries again and again. In Bengaluru, against Australia in 2013, Rohit Sharma reached 20 off 35th ball, 50 off the 71st, and the hundred in the 38th over of the innings. In Kolkata, against Sri Lanka in 2014, he was nearly caught for 4 off the 17th ball he faced, reached his 20th run off the 35th ball, but accelerated slightly earlier to bring up his century in the 32nd over of the innings. On a cold mid-week afternoon in Mohali this season, he was even slower to start, reaching 20 off 37 balls, 50 off 65 balls, and bringing up the hundred only in the 40th over. All three were ODI doubles. One time can be a charm, but to accelerate so crazily three times after having set up the innings and to make it look predictable is a perfect combination of skill, fitness and the right mental approach to ODI batting. You can be all amazed at how he manages to do it, but Rohit's reaction to it is typically relaxed. "That's my template, no?" he tends to ask. He remembers the innings clearly: reaching "50 off 70 balls", bringing up the hundred "near the 40th over", and then knowing that the bowlers can't get him out unless he makes a mistake. "That is my style of play," Rohit said. "You are set and seeing the ball nice and hard and you have understood what the bowlers are trying to do by then, and it's all about trying to play with the field once you get past 100. It's all about you not making a mistake and getting out. I am not saying it's impossible or difficult, but it's very unlikely the bowlers are going to get you out once you have scored a hundred. "So it was all about me not making a mistake and batting as long as possible. That's what I did. There is no secret or formula to it. You just have to bat and not make any mistake. The ground is good, the pitch is nice and hard, so you can trust the bounce and play the shots."

What according to Rohit Sharma is the secret or formula to hit centuries consistently on the ground?
