Match was stopped to due to heavy rain before lunch time today. NZ has declared their second inning at 267 runs at loss of three wickets and Sri Lanka require another 401 runs with all wickets are in hand. It looks like now rain has stopped and play may start soon. But if SL want to draw this match than they need to play another around 135 overs but I don't think they can do that.
In NZ so for 400+ has been scored only twice in during a 4th innings ever. And one of those was Astles 222 and no visiting team has ever scored more than 366 runs. But in this match rain may help SL as of now match is still stopped due to rain and if rain spoil whole day than SL will only need to play about 90 overs in this last innings. Still there are possibility of getting draw this match.
