Luke Ronchi and Grant Elliott's 267-run partnership fired New Zealand to a big win over Sri Lanka in Dunedin.
A world record partnership between Luke Ronchi and Grant Elliott guided New Zealand to a 108-run win over Sri Lanka in Dunedin on Friday.
Ronchi (170 not out) and Elliott (104 not out) combined for a stunning 267-run partnership for the sixth wicket - a record in one-day international (ODI)cricket.
New Zealand were in trouble when they came together, at 93-5 after 20 overs.
But Ronchi and Elliott's stunning contribution took the Black Caps to an outstanding 360-5.
Sri Lanka opener Tillakaratne Dilshan hit an excellent 116 for the tourists, who were well placed at 208-2 after 35 overs.
But a drinks break halted their momentum and New Zealand swooped, taking the next eight wickets for just 44 runs.
Sri Lanka were bowled out for 252 in the 44th over - giving New Zealand a 3-1 lead in the seven-match ODI series.
Stand-in Sri Lanka captain Lahiru Thirimanne - replacing Angelo Mathews (calf) - looked to be vindicated after winning the toss and sending New Zealand in.
Martin Guptill fell on the very first ball of the innings for a duck, while Brendon McCullum (25), Kane Williamson (26) and Ross Taylor (20) all failed to convert starts.
Thirimanne (2-36 off seven) then trapped Corey Anderson lbw for eight to leave New Zealand reeling.
But Ronchi and Elliott put together a sensational partnership, which came off just 180 deliveries.
Ronchi - who played one-day and Twenty20 international cricket for Australia - was the main man in the partnership, hitting nine sixes and 14 fours in an incredible 99-ball knock.
The hundred was Ronchi's first in the 50-over form, and he hit his last 70 runs from just 25 deliveries.
Elliott's ton was his second at ODI level, and came from 96 balls, including seven fours and two sixes.
New Zealand hammered 122 from their last 10 overs and that gave them all the momentum ahead of Sri Lanka's chase.
Thirimanne (45) and Kumar Sangakkara (nine) both fell to Elliott, who took 2-42 off nine overs as his good day continued.
Dilshan and Jayawardene gave Sri Lanka a platform - the latter hitting 17 fours and one six - but the run-rate grew too high and, as a result, a collapse followed.
Mitchell McClenaghan took the crucial wicket of Dilshan and finished with 2-56 off eight overs.
Fellow left-armer Trent Boult then ripped through the middle order, claiming 4-44.
None of Sri Lanka's middle to lower order offered resistance, as a meek collapse saw New Zealand post a big win.
And fittingly, it was Ronchi and Elliott who shared the man-of-the-match award for their outstanding contribution.
