When Sachin Tendulkar was bowled for 17 in the 2nd Test against New Zealand he did something unusual.
Normally the Little Master walks off quietly, thoughtfully and focused.
This time he swung his bat in frustration.
Sounds like a tiny change?
Yes, but it shows something from which we can all learn as batters.
Only he can know what made the difference, but it showed a crack in the temperament of one of the greatest batsmen of all time.
