Left-Arm Arm Ball

Left-arm spinner's variation that holds its line into the right-hander instead of turning across — a primary LBW weapon (Vettori, Jadeja).

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

Backspin with a slightly angled seam toward leg slip; wrist locked.

After a sequence of orthodox spinners turning into the right-hander, the arm ball goes straight on and hits the pad in front of middle.

Telegraphing with a flatter trajectory — keep the loop identical to the stock ball.
