Sri Lanka beat New Zealand by seven wickets, with more than four overs to spare, in a low scoring Twenty20 international on Sunday.
Nuwan Kulasekara ripped through the New Zealand top order as he took three wickets in the second over of the game, removing openers Brendon McCullum and Aaron Redmond and Rob Nicol with some excellent swing bowling.
Another slow and low track made scoring difficult but, as in Saturday's game, New Zealand skipper Daniel Vettori got to grips with conditions, making a stabilising 27.
Nathan McCullum's unbeaten 36 took New Zealand to 81 before they were bowled out in the 18th over.
Sri Lanka, who had lost Saturday's opening game of the two-match series, were never in trouble with Tillakaratne Dilshan's unbeaten 33 guiding his team to a comfortable victory.
The tied series was the first time that two test-playing nations had met in an official game in the United States.
