While Martin Guptill hit his 50 in 19 balls, Colin Munro smacked his 50 in just 14 balls - polishing it off with a huge six to give the Black Caps an emphatic victory over hapless Sri Lanka in the second T20 international at Eden Park on Sunday.

He smacked seven sixes and one four in his unbeaten 50 off 14 balls, the second fastest half-century in international Twenty20 history and the fastest for a New Zealand batsman. India's Yuvraj Singh holds the world record, needing only 12 balls to go past 50 in 2007.
