Tim Seifert was the match-winner for the second straight game as New Zealand clinched the T20 series against Sri Lanka with a tense four-wicket victory in Queenstown on Saturday. 

Seifert blasted a career-high 88 off 48 balls to fire the Black Caps to 183-6 from 19.5 overs after the tourists had posted 182-6 in the third and final game at John Davies Oval. The opener struck 10 fours and three sixes in an innings that bore many of the hallmarks of his unbeaten 79 when New Zealand levelled the series at Dunedin on Wednesday.
