Colombo - Trent Boult and Tim Southee led New Zealand's charge against Sri Lanka on Day 2 of the rain-hit second Test in Colombo on Friday.
The pacemen claimed two wickets each as Sri Lanka reached 144 for six at lunch when rain came down and no further play was possible.
Skipper Dimuth Karunaratne moved from his overnight 49 to score 65 and provided the only bit of resistance in the morning session, which saw 29.3 overs bowled.
Boult took two early wickets in one over after Sri Lanka resumed the day at 85 for two.
Dhananjaya de Silva on 32 and Dilruwan Perera on five were at the crease.
Southee, like Boult, also delivered a double-wicket maiden as the duo put on a superb display of seam bowling under overcast conditions.
Boult got overnight batsman Angelo Mathews caught behind for two to reach a landmark of 250 Test wickets - only the third Kiwi bowler to achieve the feat.
Boult trapped Kusal Perera lbw for nought after just three balls as Sri Lanka slipped to 93-4 and would have been in further trouble had Boult held on to a simple catch from de Silva off his own bowling a few overs later.
"Today's a special day for Trent. He's become the third highest wicket-taker for New Zealand," New Zealand bowling coach Shane Jurgensen told reporters.
"He's got great passion and energy which he brings to our team. I think the skill and execution and the way he's contributed to the team has been amazing."
Karunaratne also got a lifeline on 61 when Kane Williamson could not grab a tough chance at short mid-wicket off Ajaz Patel.
But the left-hander, who completed his 23rd Test fifty after resuming the day on 49, soon fell, caught behind off Southee for 65.
Southee struck again in the same over to send Niroshan Dickwella trudging back to the pavilion for nought.
"Tim and Trent have been doing it for a while. They've been creating wickets and they're very accurate, and they've got the ability to swing the ball," said Jurgensen.
"Today there might have been a little bit of swing with the overhead conditions, and it just seemed to be doing a little bit. They both work really hard on their fitness, and that's a big factor in their resilience.
"And they don't just play Test cricket. They play basically all formats. To play all formats and do as well as they've done is awesome."
Perera then played out the rest of the session with de Silva.
Medium-pace bowler Colin de Grandhomme and spinner William Somerville took a wicket each on the opening day after Sri Lanka elected to bat first.
Weather permitting, extended playing time is planned for the third day after two days of continuous rain interruptions in the Sri Lankan capital.
