@Setanta,
Sorry Set, it's cricket lingo.
But let's try to help. I'm assuming you had a problem with the words "strike spinner"? A spinner is a bowler in cricket who bowls with slow speed. A pacer/ fast bowler, on the other hand, will bowl fast. Now, what's a bowler? He's the equivalent of a pitcher in baseball.
THe guy in question - Shane Warne (Warnie) - is a leg spinner. I think "strike" is Oz slang for leg.
ETA: Here's some info on spin bowling in general, as I thought you'd be wondering what the heck is "leg spin"!
