Technical Breakdown

19-section schema

Definition

A delivery from an action that holds its line (or swings slightly with the arm) instead of turning — the off-spinner's primary -taker against the well-set batter (Saqlain Mushtaq, Nathan Lyon).

History

The cricket ball's cork-and- construction dates to the 1770s (Duke's of Kent); pink and white balls were introduced later for day-night and limited-overs cricket.

Grip

Same finger split as the , but with the angled toward so it leaves the hand without side-spin.

Release Point

Wrist locked, fingers stay behind the ball; backspin keeps the upright and the ball drifts with the arm.

Physics Involved

Backspin reduces , so the ball arrives a fraction fuller than expected — the and bowled trigger.

Tactical Use

Bowl after a sequence of turning off-breaks so the batter is committed to playing for spin; perfect from the to a right-hander on middle-and-off.

Common Mistakes & Drills

Telegraphing via a slower arm; release the at stock with only the wrist position changing.
