What Is Left-Arm Orthodox Spin?

Left-arm orthodox spin (abbreviated SLA — Slow Left Arm) is a finger-spin style bowled by left-arm bowlers. The ball naturally turns from off stump toward leg stump for a right-handed batsman — into the body. It is the mirror image of right-arm off-spin and is one of the most classical and widely practised spin styles in cricket.

Many teams value a left-arm spinner to provide variety — the angle of delivery and direction of turn is opposite to the right-arm off-spinner, which can disrupt batsmen who have adapted to one style.

Famous Left-Arm Orthodox Spinners

Daniel Vettori of New Zealand is one of the greatest SLA spinners in Test history with 362 wickets. Derek Underwood of England was famous for his accuracy. Ravindra Jadeja of India and Mitchell Santner of New Zealand are leading modern SLA spinners.

A left-arm orthodox spinner is particularly valuable against left-handed batsmen — the ball turns away from them (like a leg-break), creating edges to the off-side cordon.
