Things which nobody did before McCullum
#4 1st batsman to score 150 in any T20 match
18th April, 2008 will remembered by the cricketing world for 2 reasons; firstly, because it marked the beginning of the IPL and secondly, McCullum became the first ever batsman to score 150+ in T20 cricket. McCullum gave the tournament the perfect advertisement in its inaugural match by hammering 158* off just 73 balls for KKR against RCB.
It remained the highest score in T20 cricket for more than 5 years until Chris Gayle conjured 175 not out for Royal Challengers Bangalore in IPL 2013. An interesting fact is that McCullum has scored 158 not out twice in his T20 career, the second instance being for Warwickshire in July this year.
