Before Brendon McCullum swung to Wagner, Sri Lanka made 45 keeps running in 15.5 overs, and Mitchell Santner and Doug Bracewell had recently started to control a formerly energetic run rate.
Wagner instantly turned to a short-pitched assault from over the wicket - like he had done on the third day - focusing on the right-hand batsman's ribs with men getting close on the leg side.
Chandimal had been spread driving and cutting Trent Boult and Tim Southee, his furious discipline of anything free taking him quickly to a half-century. Mathews had played with gentler hands and a straighter bat, batting with quiet. Wagner gave them no width, no chance to get on the front foot, hustling them with pace, compelling rushed sly activities and unbalanced fights off the body.
Wagner's system for assault had turned out to be so imbued in the batsman's mind that they expected little else from him. Thus Mathews, in the wake of moving quickly towards the off side to let two continuous short balls whizz past his ribs, started to play the third conveyance in a comparative way. But this time Wagner rocked the bowling alley a full length. The ball collided with within his front cushion, shot between his legs and leveled center stump. Mathews had not by any means played a shot, and was the first Sri Lankan batsman to not be gotten in this Test.
Chandimal needed to hold his arrogant methodology against Wagner. He had got to 50 off 90 balls - scoring 19 off 26 at the beginning of today - however made just eight off his next 41 conveyances. Repressed into a protective personality set, he cushioned up to a ball from the left-arm spinner Santner that went ahead with the arm, and was decreed lbw not offering a shot. After an organization of 56, Mathews and Chandimal had fallen with the score on 165.
Wagner now circumvented the wicket to point the ribs of the two left-handers - Kithuruwan Vithanage and Milinda Siriwardana. He stuck them to the wrinkle with his length, and after that knocked down some pins a quick full-hurl at Siriwardana, who was hit on the back cushion as he squared up in his wrinkle. The umpire Nigel Llong gave him lbw however Siriwardana effectively explored the choice, replays shockingly proposing the ball would have missed off stump, maybe on the grounds that Wagner had conveyed from amazingly wide of the wrinkle.
Wagner was given the second new ball for the last conveyance of his first spell, which contained eight overs at paces that did not ebb.
Southee took two conveyances to hit with the new ball, swinging it once more into Vithanage from over the wicket, hitting the left-hander's cushions. Vithanage had played a venturesome innings, a run-a-ball 38 loaded with shots.
The slide was quick after lunch. Boult struck in the third and fifth over of the second session - drawing an edge from Rangana Herath and having Siriwardana gotten at short cover, both batsmen not annoying with resistance.
Sri Lanka went down swinging, and were rocked the bowling alley out for 282. In any case, the way that an unpracticed batting line-up had kept going 95.2 overs in the wake of playing 117.1 in the first innings will be some comfort for a group modifying from the retirements of Kumar Sangakkara and Mahela Jayawardene.
