Sri Lanka trail the West Indies by 104 runs with two wickets in hand after the rain-affected third day of the second Test in Antigua.
Only 40.3 overs were on a day which saw four rain interruptions.
Sri Lanka took ther score from 3-136 overnight to 8-250 in reply to the West Indies' 354 before a final, heavy shower ended play.
First Test century-maker Pathum Nissanka was 49 not out while Lasith Embuldeniya had yet to score.
Nissanka had faced 119 balls and provided a solid anchor in the late stages of Sri Lanka's innings.
The tourists lost two wickets in the morning session with Dinesh Chandimal scoring 44 and Dhananjaya de Silva 39, both batsmen failing to convert good starts.
Chandimal fell to a trap set by Shannon Gabriel, who tempted him into hooking a short delivery and had him caught on the deep square leg boundary.
De Silva will rue not reviewing his dismissal, as part-timer Jermaine Blackwood was brought on just before the second new ball became available.
His first delivery trapped De Silva lbw but it was turning sharply, which should have prompted a player review.
De Silva walked off without hesitating after being given out, only to find that had he reviewed he would have been given not out as the ball would have missed his wicket.
After lunch, and in between rain beaks, Niroshan Dickwella was caught behind for 21 but only given out after a review and Suranga Lakmal (6) was caught at mid-on off Alzarri Joseph.
Dushmantha Chameera went cheaply after tea leaving Nissanka and Lasith Embuldeniya at the crease.
Rain had the final say and the day was ended by a heavy shower and by darkening skies just.
The shower was fleeting but left damp patches close to the pitch at the Sir Vivian Richards stadium and the umpires called off play for the day about 45 minutes later.
The first Test of the two-match series at the same venue ended in a draw last week.
