Typically, swing bowlers use the new ball to deviate it in the air to outwit batsmen.

But the Pakistan fast bowlers, considered to be the pioneers of the skill, stunned the cricket world in the 1980s by swinging the old ball in the reverse direction.

Armed with the weapon, popularly called as reverse swing, the Pakistan pace duo of Wasim Akram and Waqar Younis became deadlier with the old ball.

The evening dew, quite normal in the subcontinent during this time of the year, might also spoil the chances of more spinners making it into their teams as it gets very difficult for them to grip the ball once it gets wet.

New Zealand captain Daniel Vettori, an off spinner, is well aware of the problems.
