Cardiff: New Zealand broke their losing streak against Sri Lanka by winning their ICC Champions Trophy match by one wicket in a low scorer at Cardiff on Sunday.
Chasing a meagre 139-run target, New Zealand were reduced to 134/9. However, Tim Southee held his nerve to guide Kiwis to victory with 13.3 overs to spare.
Daniel Vettori was the sixth man to go as he would consider himself unlucky to be given LBW to Lasith Malinga despite having an inside edge.
Since, New Zealand had used up their review earlier, the decision could not be referred to the third umpire.
Tillakaratne Dilshan gave New Zealand fifth blow by trapping James Franklin in the 15th over.
After losing opener Luke Ronchi in the fourth over, New Zealand were quite calm in their approach.
However, the Lankans fought back with quick wickets after lunch and New Zealand, from 48/1, were reduced to 49/4.
The Kiwis lost Kane Williamson, Ross Taylor and Martin Guptill in quick succession bringing Sri Lanka back in the game.
Guptill was the fourth man to fall as he became second victim of Shaminda Eranga after 25-run knock.
Eranga, earlier, scalped Luke Ronchi (7) early after New Zealand bowled out Sri Lanka for just 138 .
New Zealand went to lunch at 26/1 with Martin Guptill and Kane Williamson at the crease.
After game resumed, Lasith Malinga trapped Williamson (16) at the score of 48.
After addition of one run on board, Rangana Herath gave Kiwis third blow by removing Ross Taylor for a duck.
Earlier, McClenaghan, who turns 27 on Monday, celebrated early as he led an impressive Black Caps display in the field after Sri Lanka won the toss and elected to take first strike.
Veteran Kumar Sangakkara played a lone hand for the Islanders with 68, his 75th one-day half-century, but five of the other six top-order batsmen failed to reach double figures as the team folded in 37.5 overs.
Sri Lanka never recovered after losing Kusal Perera off the first ball of the match when New Zealand captain Brendon McCullum flew to his left at second slip to pick up a brilliant catch off Kyle Mills.
Tillakaratne Dilshan hit 20 off 18 balls when he was bowled by McClenaghan to make Sri Lanka 27-2.
It soon became 33-3 as veteran Daniel Vettori, playing his first one-dayer since the World Cup semi-final against the same opponents in Colombo two years ago, struck with his fourth delivery.
A slower, flighted ball caught star batsman Mahela Jayawardene on the back foot and umpire Bruce Oxenford upheld Vettori's loud appeal for leg-before.
Mills claimed another wicket in the ninth over when Dinesh Chandimal, attempting a huge drive outside the off-stump, edged an easy catch to wicket-keeper Luke Ronchi.
Nathan McCullum is the Man of the match for his knock of 32 and picking up a couple of wickets.
Earlier, Sri Lanka have won the toss and elected to bat first in their Champions Trophy opner against New Zealand at Sophia Gardens, Cardiff on Sunday.
Shaminda Eranga has been included in place of Nuwan Kulasekara. For New Zealand, Daniel Vettori comes back for Grant Elliot. He played his last ODI over two years ago, in the 2011 World Cup.
