Top-Spinner (Wrist Spin)

A wrist-spinner's delivery with the spin axis tipped forward — pure top-spin that dips and bounces over the bat (Shane Warne's bowled-Strauss variant).

Finger- and wrist-spin have been part of cricket since the 18th century; over-arm spin was legalised in 1864, and the ICC's 15° flex tolerance (2005) modernised its regulation.

Wrist squared up, fingers roll over the top of the ball; seam rotates forward end-over-end.

Top-spin generates downward Magnus force — shorter perceived length, then steeper bounce off the pitch.

Aim a fraction fuller than stock to a forward-defending batter; the dip traps the bat-pad catch.

Hooking the wrist under instead of over — produces a half-rolled leg break with no extra bounce.
