Chandimal, on 86, and Prabath Jayasuriya, on four, were batting at the close of play with Sri Lanka leading by 333 in their second innings.

He reached his fifty and put on 41 runs with Maheesh Theekshana for the ninth wicket in a repeat performance from the hosts, who had hit back from 133-8 to post 222 in their first innings.
