Whatever it takes!!!
He equalled the record in that SL match but didn't break it.
Yeah, also I think Warney got his 600th wicket maybe in Chennai, not exactly the record. My memory is failing me, cannot recollect if it was the record or 600th wicket that he got there.
EDIT: He did go past Murali at Chennai, with the wicket of Irfan Pathan. 533rd wicket. Thanks Google.
