What is the basic difference between Doosra and Teesra? I know off-spinner bowls the other one which is called Doosra but what is Teesra and how is it different to Doosra?
Doosra and teesra, both these bowling techniques were invented to deceive the batsman.
Doosra and teesra both are Urdu words which means "the second one" and "the third one" respectively.
Doosra is the technique use by an off spin bowler and it results in leg spin, but the bowling action remains as off-spin (for left-arm bowlers the case is in reverse).
Teesra looks like the ball will turns a lot in off or leg but it results in less turn. The batsman can't judge the ball to where it would turn.
Both these techniques were invented by Saqlain Mushtaq.
Doosra is used well by most of the current off-break bowlers but, teesra is being used successfully by Saeed Ajmal.
So far this delivery has been used for well over a hundred years. But the delivery has recently been re-invented by Saqlain Mushtaq and he occasionally used it. He has stated that the teesra is still a work in progress and that he wants to hone the delivery so that the batsman become even more confused about where the ball is going to spin and whether it will spin at all. Saeed Ajmal claimed to have learned this art and has used it occasionally in the 2011 World Cup and after that
