New Delhi: Pakistan has been in the forefront of not only producing a string of some exceptional fast, swing and spin bowlers, but more importantly, has introduced and pioneered innovations (even inventions) of bowling styles and deliveries that were never heard or seen of before.
Leading examples in this respect include ‘reverse swing' and the ‘doosra.'
Reverse swing is when a fast bowler is able to swing the old ball. Technically the ball should only swing when it's new, but when Pakistani fast bowlers invented the trick of revers swing with the old ball.
