Christchurch: A sublime six-wicket haul by Trent Boult and half centuries from Tom Latham and Jeet Raval gave New Zealand a vice-like grip on the second Test against Sri Lanka in Christchurch on Thursday.
At the end of the second day, New Zealand were 231 for two, holding an ordering 305-run lead in their second innings with eight wickets close by.
Sri Lanka's expectations of taking the arrangement choosing Test were seriously marked in a 15-ball masterclass of swing rocking the bowling alley from Boult when he took six wickets for four runs.
It gave New Zealand a 74-run first-innings lead, which Latham and Raval reached out to 195 with a century opening stand.
Kane Williamson and Latham included a further 68 for the second wicket until Williamson played a lethargic shot to Lahiru Kumara and was gotten at first slip for 48.
At the end of the second day, Latham was on 74 with Ross Taylor on 25.
Latham, who featured in the principal Test with an unbeaten twofold century, has confronted 213 conveyances.
He got a real existence on 32 when he top-edged Suranga Lakmal to fine leg where the ball snuck past the fingers of a jumping Dushmantha Chameera.
Patel, who worked with Latham to deliver the primary wicketless session in the Test when they batted from lunch to tea, was out in the second over after the resumption for 74 when he edged Dilruwan Perera to Kusal Mendis at short leg.
Sri Lanka continued at 88 for four harboring musings of upgrading New Zealand's first innings 178.
Yet, nine overs and 16 runs later their last six wickets were gone, all taken by Boult, who completed with a lifelong best six for 30.
Just Angelo Mathews had the ability to keep Boult out and he was unbeaten on 33 at the end of the innings.
Boult set off the crumple when he had Roshen Silva gotten by Tim Southee at third slip for 21.
A jumping Southee delivered a tremendous one-gave get in Boult's next over to evacuate Niroshan Dickwella for four.
Dilruwan Perera, Suranga Lakmal, Chameera and Lahiru Kumara all misread Boult and went rapidly leg before wicket without scoring to end the innings.
Perera and Lakmal fell in sequential conveyances with Chameera hindering the following ball to maintain a strategic distance from a cap trap before he was expelled with the second ball he confronted.
There was development off the crease for Suranga Lakmal and Kumara when New Zealand started their second innings, yet the Sri Lankan quicks did not deal with the sort of sudden development noticeable all around that Boult had found.
