T20 was introduced in 03 just over 10 years now. Narine has been a magician in this form against all teams top or low and in any condition throughout the world.
I think he is the greatest T20 bowler ever and unlikely to be matched.
His career figures in T20 reads currently:-
Matches - 114 - Wickets - 150 - Average - 15.56 - Economy - 5.38 - Strike - 17.3
His economy rate is simply outstanding. Not even other top T20 bowlers according to wicket taking charts in T20 comes close to him in T20s
