New Zealand blitzed the second Twenty20 against Sri Lanka in Auckland yesterday with a whirlwind display by Martin Guptill and Colin Munro to set up a nine-wicket win.
Munro brought up the winning runs with a six to be unbeaten on 50 after 14 balls, the second fastest Twenty20 half-century behind a 12-ball spree by India’s Yuvraj Singh against England in 2007.  
It was also the fastest 50 by a New Zealander, eclipsing the 20-minute-old record set by Guptill who took 19 balls to get there at the top of the innings.
Guptill was the only wicket to fall in the New Zealand innings, out for 63 off 25 balls with six fours and five sixes, while Munro clouted seven sixes and one
four. It took New Zealand exactly 10 overs to mow down the modest 143-run target with Kane Williamson unbeaten on 32. New Zealand captain Williamson said it was “pretty special” to see Guptill and Munro flay the bowling.
“I thought it would be a bit of a scrap on that wicket as it was holding up a fraction, but it didn’t seem to be a problem for those two guys and they cleared the ropes consistently,” he said.
“It was exciting to see.”
The victory gave New Zealand a clean sweep of the tour by Sri Lanka, winning the Twenty20s 2-0 to go with their 2-0 domination of the Tests and 3-1 win in the one-dayers.  

‘Bad batting’
Sri Lanka’s resounding defeat in the Twenty20 matches saw them slip from first to third behind the West Indies and Australia in the world rankings.  
As has happened throughout the tour, the Sri Lankan top order failed to click. After being sent in to bat, they were all out for 142 with only Angelo Mathews showing any resistance with an unbeaten 81.
It was Mathews’ highest score in the shortest form of the game, easily eclipsing his previous best of 58 against England five years ago. Tillakaratne Dilshan with 28 was the only other Sri Lankan to reach double figures as the wickets tumbled.  
Sri Lanka’s downfall was as much a result of poor shot execution—repeated ill-timed slogs—as it was good bowling and fielding by New Zealand.  
“We just played bad batting out there,” Sri Lanka skipper Dinesh Chandimal said. “Thanks to Angelo he put a comfortable total at the end, but I’m really disappointed with the way we played.”
The chief destroyer for New Zealand was Grant Elliott with four for 22 in his first game back at Eden Park since his six off the penultimate ball against South Africa to get New Zealand into the World Cup final last year.
