NZ rout Pakistan in Test to lead rankings

Kyle Jamieson took his second five-wicket haul of the match as New Zealand beat Pakistan by an innings and 176 runs in the second Test to sweep the series 2-0 and top the world rankings for the first time.

The young paceman took 6-48 to add to his 5-69 from the first innings as the Blackcaps dismissed Pakistan for 186 to seal an eighth straight home Test series triumph with victory inside four days at Christchurch's Hagley Oval.

The win also pushed New Zealand firmly into contention for one of two berths in June's inaugural World Test Championship final at Lord's.

As much as player-of-the-match Jamieson's fine bowling, the win was built on the magnificent 238 skipper Kane Williamson scored in New Zealand's only innings, which enabled the hosts to declare on 6-659.

"Even though the result on paper was very much in our favour, we know that when you are playing quality opposition, it's the small margins," said Williamson, who was adjudged player of the series.

"We won those small margins and had a bit of luck go our way as well."

Pakistan managed 297 in the first innings and only an extraordinary rearguard action was going to prevent a heavy defeat when they resumed on 1-8 after Jamieson had removed opener Shan Masood on Tuesday night.

Mohammad Abbas was caught behind off a Trent Boult delivery before Jamieson got into the swing again to send back Abid Ali and leave the tourists labouring to lunch at 3-69.

Jamieson secured his fourth five-wicket haul in six Tests in the second session by dismissing Haris Sohail, Azhar Ali and stand-in skipper Mohammad Rizwan.

Boult dismissed Zafar Gohar, who made 37, to seal the victory for New Zealand who remain unbeaten at home since being beaten by South Africa in 2016-17.

"I'm very disappointed that I didn't get a result for Pakistan as they put their faith in me," rued Rizwan, who led in the absence of their injured regular skipper Babar Azam.

"We tried our very best but we didn't do very well. As the captain, as a player, I take responsibility."

With the Border-Gavaskar Test series between Australia and New Zealand still running, New Zealand's reign as World No.1 may yet be short-lived. The Vodafone Test series is locked at 1-1 ahead of Thursday's third match in Sydney, where a positive result for Australia would take them back above New Zealand.

That would only be provisional though, as the ICC only officially confirms rankings at series end. Australia need to win the Test series by any margin to overtake New Zealand, while India would need to win in both Sydney and Brisbane and get a 3-1 series result to take the world No.1 ranking. A drawn Australia-India series would see New Zealand retain top spot.
