Left-Arm Orthodox Spin: The Bowler Who Spins Away from Right-Handers

What is left-arm orthodox spin?

Left-arm orthodox spin (also called SLA — slow left-arm) is finger-spin bowling delivered by a left-handed bowler. Against a right-handed batter, the ball turns from leg stump to off stump — spinning away from the right-hander. This is the mirror image of an off-spinner's stock delivery (which turns from off to leg). Left-arm spin is 'orthodox' because it uses the same seam-up, finger-spin action as right-arm off-spin — just from the opposite hand.

The natural advantage against right-handers

Left-arm orthodox spin creates LBW risk on the right-hander's stumps from an angle that right-arm off-spin cannot replicate. When a left-arm spinner bowls around the wicket to a right-hander (coming in from the left), the ball that turns is heading into the stumps — creating LBW danger. A ball bowled from around the wicket that then turns more than expected can also pitch outside leg but still clip off or middle stump. This angle is particularly threatening in Test cricket where slow, turning pitches amplify the turn.

Key deliveries

The stock delivery turns from leg to off. The arm ball continues straight (no turn) — the left-arm spinner pushes the ball past the right-hander's outside edge or into the stumps on the off side. The faster delivery ('quicker ball') is bowled at reduced revs and increased pace to skid through, sometimes producing LBW or bowled when the batter is playing for turn. Some left-arm orthodox bowlers also bowl a 'chinaman' (left-arm wrist spin) occasionally as a surprise variation, though this is distinct from their core action.
