Dinesh Chandimal and Dimuth Karunaratne forged a 147-run partnership to propel hosts Sri Lanka to a lead of 202 on day three of the first Test against New Zealand on Friday. Sri Lanka were 237-4 at stumps in Galle with Angelo Mathews and Dhananjaya de Silva, both on 34, to resume in the morning. Karunaratne (83) was on song, punishing loose deliveries and forcing New Zealand to spread the field to protect the boundaries. Chandimal (61) was more conservative. "When you play in Galle there is a way I play, and I back that style," Karunaratne said. "Rather than trying to defend, the best way forward is sweeps and reverse sweeps on that wicket," he added.
