Reverse wrist/ off-break doosra bowling needs a bent elbow - but chucking is not necessary

*

This report about Ajmal clarifies what seems anatomically necessary: that a reverse wrist spinner/ off-break-doosra bowler very probably needs to have a bent elbow, but does not entail chucking

This is quite simply because the elbow needs to be bent in order to rotate the arm (specifically to rotate the shoulder) to point the elbow towards slips (for a right handed batter) - which enables the forward flip of the wrist to generate the doosra.

Note added 12 March 2012 - it is notable that the two best doosra bowlers so far seem to have had a permanently bent, unstraightenable elbow on their bowling arm.

Murali had this congenitally (i.e. he was born with a bent elbow), while Ajmal had a bent elbow as a result of an accident.

This suggests that unless a bowler has a bent elbw, he will probably not be a really effective (as well as legal) doosra bowler.

The possible exception is Saqlain Mushtaq; but for whatever reason, nobody seems to be able to replicate his method.
