West Indies in trouble at 113-6 at close of second day, despite Chase's 5-83, Brathwaite's 41
Ramesh Mendis, who took 3-23 and Praveen Jayawickrama 2-25 were the main destroyers for the hosts as the West Indies collapsed from a solid start from Captain Kraigg Brathwaite, who made 41 and Jermaine Blackwood (20).
Brathwaite and Blackwood were hardly troubled by the Sri Lankan bowling as both took few risks while making effort to rotate the strike as best they could against tight-bowling and a close field. They ran singles and pierced the field for the occasional boundary steadily building a foundation for the chase.
However, the promising start would eventually unravel in the most disappointing fashion.
At 46-0, Blackwood was trapped lbw playing down the wrong line to a Lasith Embuldeniya delivery that was going on to hit leg stump. Nkrumah Bonner was out soon after as after having faced 11 balls, Jayawickrama had him caught at slip for one.
His dismissal triggered a slide that saw the West Indies lose four wickets for 53 runs. Among the wickets to fall was that of Brathwaite, who was caught at leg slip off Mendis for 41 as close of play approached.
The wickets of Shai Hope (10), Roston Chase (2) and night watchman Jomel Warrican followed in quick succession as the West Indies slipped further from 80-3 to 100-6.
Kyle Mayers 22* and Jason Holder 1* are the batsmen at the crease when play ended for the day.
Earlier, Chase took 5-83 to restrict Sri Lanka, resuming from their overnight total of 267-3 were bowled out for 386.
The hosts lost their last seven wickets for 119 runs after overnight batsman Dhananjaya de Silva, who resumed from his overnight score of 56, added five runs to his score before he was first out, hit wicket to the bowling of Shannon Gabriel for 61.
The big wicket of Dimuth Karunaratne, 132 overnight, followed soon after when he was caught at slip for 147.
Chase also removed Dinesh Chandimal for 45 as he and Jomel Warrican (3-87) ran through the remainder of the Sri Lanka batting.
