Boult seven studs New Zealand's 204-run victory

Trent Boult took a career-best 7 for 34 to send Windies packing as New Zealand sealed the One-Day International series with a game to spare in Christchurch on Saturday.

New Zealand posted a formidable 325 for 6, after being asked to bat, with the last ten overs yielding 103 thanks to a frantic 130-run sixth-wicket partnership between Henry Nicholls (83 not out) and Todd Astle (49).

Windies needed a strong start but it got quite the opposite. Boult had figures of 3 for 6 after his first three overs to derail the chase.

The visiting side eventually slumped to 121 all out to give New Zealand victory by 204 runs to go with its five-wicket win in the first ODI on Wednesday. Shai Hope's 23 was the top score for Windies.

While Boult will rightfully get most of plaudits, Lochie Ferguson dented the Windies middle order with three wickets in ten deliveries, including Jason Mohammed and Rovman Powell off successive balls.

Earlier, George Worker and Colin Munro got New Zealand off to a flier, before Sheldon Cottrell (3 for 62) snapped up Munro (30) and Neil Broom (six).

There was no let-up from the home side, though, as Worker and Ross Taylor ensured the run rate was better than a run-a-ball in a 58-run partnership before Worked fell to Ronsford Beaton for 58.

Jason Holder, the Windies captain, then reduced New Zealand to 186 for 5, snaring Tom Latham and Taylor in the space of 11 balls, but the visiting side couldn't drive home the advantage.

Nicholls's career-best 83 off 62, which featured two sixes and seven fours, and Astle's 49 off 45, from No. 7, ensured New Zealand finished with a flourish and gave the bowlers ample amount of runs to express themselves.

Hagley Oval hosts the third and final match in the series on Tuesday.
