Wellington: New Zealand opener Tom Latham flayed Sri Lanka's bowlers with an unbeaten 264 Monday before the tourists' top order failed again to leave them on the verge of a heavy defeat in the first Test in Wellington.
Latham walked off to a standing ovation at the Basin Reserve after carrying his bat and helping New Zealand to 578, a commanding first-innings lead of 296.
Seamers Tim Southee and Trent Boult then combined to remove Sri Lanka's top order, reducing them to 20 for three at stumps on Day 3.
Boult dismissed Danushka Gunathilaka on three, while Southee snared Dimuth Karunaratne for 10 and Dhananjaya de Silva for a duck, taking his tally for the match to eight.
The pair, along with short-ball specialist Neil Wagner, will be relishing the prospect of having two full days to attack Sri Lanka's misfiring batting line-up.
But the day belonged to Latham, who added steadily to his overnight total of 121, offering no chances to the frustrated Sri Lankans.
It was the sixth best Test score by a New Zealander and the highest this year by a batsman from any nation.
His innings, which lasted more than 11 hours, also continued a horror run at the Basin Reserve for Sri Lanka, where they have now conceded double centuries to four New Zealanders.
New Zealand skipper Kane Williamson helped the Black Caps reach their imposing total with a sparkling 91, while Ross Taylor and Henry Nicholls both reached 50.
Lahiru Kumara was the pick of a Sri Lanka attack that struggled on a flat wicket, taking four for 127.
Taylor was dismissed for 50 in the first over of the day after failing to add to his overnight score, thanks to a sharp catch from Karunaratne.
The ball was forcefully struck and initially bounced off Karunaratne's hand at silly mid-off before he recovered to grab it as he tumbled to the ground.
Henry Nicholls also went for 50 after lunch trying to take on spinner Dilruwan Perera.
BJ Watling followed without scoring when he tucked his bat awkwardly under his arm as he ducked a Kumara bouncer and the ball clipped it on the way through.
Colin de Grandhomme scored three sixes during an aggressive innings but fell on 49 attempting to bludgeon a fourth.
Sri Lanka, ranked sixth in the world, have lost their last five Tests against New Zealand and suffered a 3-0 home Test series whitewash against England last month.
They have faced upheaval in their coaching and selection ranks in recent weeks and arrived in New Zealand low on confidence.
In contrast, the fourth-ranked Black Caps entered the two-match contest buoyed by their first away Test series win over Pakistan in 49 years.
The New Zealanders are looking for a fourth straight Test series win after also defeating England and the West Indies in the past 12 months.
