Sri Lanka's middle-order batter Sonal Dinusha struck his second hundred of the match to help the hosts salvage a draw after they were asked to follow on in the second test against India on Thursday.

Dinusha, who made a stellar 133 not out, forged a century stand with Keshara Nuwantha (46) in a remarkable fightback for Sri Lanka, who began the final day 16 ahead with only four wickets in hand.
