>Batman is a bastard when he sledges

Well, there is no such thing as a batman in cricket. There are batsmen, but no batmen, as least not that I know of.

As for the comment about Kiwi sledgers, it was followed up by a piece of cricketing irony, or possibly just plain sarcasm, namely, "A leggie doesn’t take a bozillion Test wickets by deceiving people." Deceiving people is, of course, precisely how a good legspinner does take wickets. Although in Warnie's cse, it might be argued that he boored them to death.
