For the second time this series, Sri Lanka's fast bowlers had West Indies on the mat, only to concede the advantage as the day progressed, reports ESPNCricinfo.
The thorn on both occasions was Shane Dowrich, the spunky wicketkeeper-batsman who stayed unbeaten on 60, at the end of the first day at the Kensington Oval that saw only 46.3 overs being bowled because of rain interruptions.
In Port-of-Spain, he put on 90 for the sixth wicket with Jason Holder to set up a tall first-innings score in a match-winning effort.
In Bridgetown, in the Caribbean's first ever pink-ball Test, the pair's unbroken 79-run stand revived West Indies from a hopeless 53 for 5 to 132 for 5 at stumps.
This after Holder elected to bat on what wicketkeeper-turned-broadcaster Jeff Dujon described as "the greenest Barbados surface" he had seen.
Green as it was, there were patches of brown on either ends that made life difficult for batsmen, with certain deliveries rearing up and adding to the unpredictability of the pink ball.
This made the sixth-wicket association all the more compelling, as they provided a batting lesson for their floundering top order, who kept an agile slip cordon busy all afternoon.
Dowrich's seventh Test fifty was his second 50-plus score of the series, after his maiden Test century in the first Test.
He was particularly severe on the short ball, unafraid to pull in front of square, particularly off Lahiru Kumara - whose fastest delivery was clocked at 148.1kph.
Holder, meanwhile, was solid and composed to make a steady 33. The pair's calculated approach, particularly under lights, stood out, even though Sri Lanka could claim the day as their own.
