HARARE, Zimbabwe (AP) Sri Lanka stretched its lead over Zimbabwe to 411 before rain intervened on Day 4 of the first test at Harare Sports Club on Tuesday.

Opener Dimuth Karunaratne made 110 in Sri Lanka's second innings and the tourists were 247-6 when rain washed out the last hour-and-a-half of the day's play.

The rain delay makes it a little easier for Zimbabwe's hopes of saving the test.

With Sri Lanka 5-0 overnight, Karunaratne's fourth test century helped the tourists score at nearly four runs an over as they put themselves in position to push for victory in the first of two matches against test cricket's strugglers.

Karunaratne was part of a 94-run partnership with Dhananjaya de Silva (64) for the fifth wicket to keep Sri Lanka surging ahead.
