England in India 2012-13 : England shrug off new R Ashwin mystery ball | Cricket News | India v England | ESPN Cricinfo
I really don't know why spinners do this. Mystery ball? You have one traditional off spin and then the carrom ball which turns the other way(kind of legbreak). Now what is mystery ball going to do? Turn both ways in a single delivery? But if they are doing it for mind game then IDK.
