Jacques Kallis, the South Africa all-rounder, has admitted that, like many specialists, he too did not buy into the idea of Twenty20 cricket when it was first mooted.
Only on realising its popularity and inevitable growth was Kallis persuaded to work on his performances in the shortest format, and he soon found it improved other aspects of his game.
Kallis recently featured in a one-off T20 against India in Johannesburg and made 61 off 42 balls.
The match was played in his honour and the proceeds donated to his scholarship foundation.
He also features regularly for Kolkata Knight Riders in the IPL.
The most obvious positive effect Kallis identified was that T20 cricket has helped speed up the sport as a whole.
