Googly / Wrong'un

A leg-spinner's delivery that turns the opposite way — out of the back of the hand, looking like a leg-break in the air (Warne, Kumble, Rashid, Chahal).

'Googly' entered cricket lexicon around 1903 via English leg-spinner B. J. T. Bosanquet; the term likely evokes the confused, 'goggling' look of the batter.

Invented by B. J. T. Bosanquet around 1900 (and still called 'bosie' in Australia); a staple of every top wrist-spinner from Warne to Kumble to Rashid Khan.

Advanced — high-skill ceiling, requires drilled repetition and biomechanical screening before match use.

At delivery, the wrist rotates so the back of the hand faces the batter — the inversion is the deception.

Same arm speed as the leg-break; the only change is wrist rotation late in the action.

Side-spin reversed produces opposite-direction turn; arrives slightly slower because the wrist position robs a fraction of the snap.

Bowl to a left-hander as a stock LBW threat, or to a right-hander to trap them across the line.

Telegraphing via a higher arm or different action; train so the only differentiator is wrist position. Slow-mo video from front-on is the coach's primary diagnostic.
