I'm just on the internet at the moment discussing field settings for Wrist Spinners and needed to upload a diagram of this one here. It's discussing the approach whereby you leave a dirty great gap in the field (The hatched section) to encourage the batsman to hit the ball through there. In this instance - I'd be bowling on an off-stump line trying to encouarage the batsman to drive the ball through that area with a straight bat. With the ball going away from the edge of the bat with turn off the wicket (leg breaks) at some point I'm going to find an edge? I suspect that such a radical field would only be used on tail-enders, but I'll see what the others on the forum say...
