The 30-ball ton was, oddly, the least surprising part of what Abhishek Sharma did at the Arun Jaitley Stadium. It isn't even his fastest hundred. What's odd about the innings is what it says about the number sitting next to that extraordinary strike rate: his average.

Somewhere in Abhishek Sharma's memory, though, there's a faster century still. It came two years ago, for Punjab against Meghalaya in a Syed Mushtaq Ali Trophy fixture nobody outside domestic cricket was watching: 28 balls, no fanfare.
