What is a googly?
A normal leg break spins from the leg to the off side, away from
a right-handed batsman, a googly spins the other way, from off to
leg, into a right-handed batsman and is distinct from an off break
delivery. The bowler achieves this change of spin by bending the
wrist sharply from the normal leg break delivery position. When the
ball rolls out of the hand from the side near the little finger, as
in a normal leg break, it emerges with clockwise spin from the
bowler's point of view. A googly may also be achieved by bowling
the ball as a conventional leg break, but spinning the ball further
with the fingers just before it is released.
