Black Caps opener Tim Robinson was dismissed first ball of the match and was joined by Mark Chapman two overs later as the New Zealand top and middle order struggled. Will Young (30 from 32) was the only top six batsman to get beyond five runs with Mitchell Santner (19 from 24) and Josh Clarkson (24 from 25) helping the Black Caps get by 100.
Wanindu Hasaranga (4-17) and Matheesha Pathirana (3-11) did the damage for the home side.
But Sri Lanka also struggled with the bat, with Nissanka scoring more than half his side’s total. Bhanuka Rajapaksa (15) and Maheesh Theekshana (14) were the only other players to reach double figures. Despite that, they still looked a strong chance to win the series with Nissanka still at the crease and wickets in hand at the start of the final over.
But the golden arm of Phillips, which was also vital in the test series whitewash of India, rescued New Zealand yet again.
“At the change of innings, I just wanted the team to fight as a unit,” New Zealand skipper Santner said.
“There was a bit there for seam and spin and we spoke about taking wickets up top ... We wanted to apply pressure, bowl in right areas and let the pitch do the work. Lockie and GP were fantastic.”
