"Doosra" an urdu word for the "second or the other one" is common cricketing term but has the revolution of the doosra prevented bowlers from mastering the pehela (the first one). Are young bowlers too infatuated with the doosra they have forget to develop the stock off-spinner ? Secondly, why is doosra hard to bowl and can it be bowled without the bending of the arm ?
Apart from Graeme Swann, all the other off-spinners in the world currently have a delivery that spins away from right handers or at least attempt it. Swann gets majority of his wickets with a well spun off spinners, it seems majority of the upcoming off spinners are trying to get wickets with variety. There are deliveries like the doosra, carrom ball or a sudoku. Finger spinners are relying on variety and forgetting to develop a stock ball, which should be the primary delivery.
Since Saqlain invented the doosra it has become a necessity, so much so, it is now seen as the most important delivery of the off spinner arsenal. Players modify their actions to ensure the doosra can be delivered, but rarely modify their actions so they can get more purchase or revolutions on an off break. Recently, Ashley Mallet in his column in cricinfo said "modern off spinners are not spinning the off break viciously, so they need to have all the variations. Once the batsman pick the variations the off spinners are clueless".
When Saqlain, Murali and Harbhajan's had their off spinner turning sharply that is when the dossra was menacing. All the bowlers over years slowly lost the off-spinner and the doosra became an infatuation. At least all the bowlers started on right path on having a sharp off break, something that is not common in modern spinners. Offcourse the evolution of twenty20 and ODI has changed the way spinners are groomed but the basics art of spinning a ball is absent.
After interviewing some academy coaches in Mumbai the common answer is finger Spinners are obsessed with a doosra delivery and are forgetting to learn a classic off spinning ball. Mandar Dalvi an spinning coach at Vidarbha said "kids don't know how to bowl the art of a off break but still want to learn the doosra immediately".
It may be time to go back to the basics in terms of spin bowling to ensure the art is not lost and the traditional off spinners still have a place in cricket. Either the doosra should not be taught at junior cricket, or there may be a requirement to overlook the legality of a the action when a doosra is delivered.
Why is it hard to bowl and is it legal ?
Out of all the new deliveries the doosra remains the toughest to pick for a batsman. It is also a delivery that raises the eye brows of many experts, in terms of its legality. Australian junior level coaches says "It is a delivery that we do not encourage to bowl, but it is the first question all kids ask."
The ICC have accommodated this delivery - they changed the rules to allow these bowlers to bend their elbow 15 degrees. To be more specific the rules was changed to accommodate Murali after the flare up back in 1995. Experts have their opinions of whether Murali did throw or not but now Murali has gone maybe the rule needs an overview.
All past spinners will tell you it is impossible to bowl a delivery for a finger spinner which spins in different direction without the flick of the elbow. To deliver the doosra the back of the hand faces the batsmen causing the elbow to bend, it is mechanics of the body. It becomes a jerk which in theory constitutes a throw. Any person sitting at home should try it without bending or twisting the elbow, it is not possible.
The other observation is the bowlers who have bowled the doosra in the recent times have always covered their elbows by wearing a long sleeve shirt. Harbhajan, Saqlain, Botha and Ajmal always bowl in a 3/4 sleeve shirt.
Not only are young cricketers obsessed with doosra, the game's administrators seem to be crazed by it as well. Maybe doosra will become such an obsession in the future the "phela" (first one or the original) will become new doosra in the future.
