Dale Steyn could be just the latest nuclear-tipped arrow that South Africa have drawn from their seemingly bottomless quiver of classy fast bowlers.

The trouble, for opposing batsmen, is that he is rather more than that. Pure pace is one thing, pinpoint pure pace distinctly another.

Pinpoint pure pace poison-tipped with aggression still another. Add the regularity with which Steyn moves the ball away from right-handers, and the way his deliveries skid at batsmen - a lack of height isn't all bad - and the danger he poses is obvious.
