Arm Ball in Cricket

An off-spinner's delivery that goes straight on with the arm instead of turning.

What is a Arm Ball?

Every good spinner needs a straight delivery to deceive batters expecting turn. The arm ball is bowled with minimal spin — it holds its line through the air and off the pitch. Batters who have been turning the bat to play for off-spin are suddenly playing across a ball that goes straight. Often traps the batter LBW or through the gate between bat and pad. The arm ball is most effective when established after several deliveries of significant turn.

In play
