West Indies drew inspiration from their defence of 137 in the 2012 World T20 final at the same venue, to earn a farewell win on this tour, captain Darren Sammy and Man of the Match Dwayne Bravo said.

West Indies hit 162 batting first on this occasion, which Sammy described as better than a par-score, given the conditions. Sri Lanka had reached 93 for 1 in the 13th over, before West Indies' bowlers sparked a collapse that cost the hosts nine wickets for 46 runs. The visitors won by 23.

"When we played the final here we scored 130-something and defended it - that was a reminder for the guys when we went into field," Sammy said. "We had a good start. We controlled our play. They didn't get off to a flyer. They didn't get used to any particular bowler. The plan was to give one-over spells to the bowlers and it worked. We kept on picking wickets every time they looked like building a partnership."

Bravo was instrumental to the victory, claiming 4 wickets for 28, including the scalp of Shehan Jayasuriya, which set the collapse in motion. That dismissal had been made possible by a spectacular outfield catch from Andre Russell, who sprinted to his left from long on, and intercepted the ball low to the ground. Sri Lanka's top-scorer Tillakaratne Dilshan had also been out to a very good catch from Jason Holder.

"Our fielding is what won us the game," Bravo said. "We said to the guys at the half-way stage that a few years ago we scored 137 and defended it. Sri Lanka had Sanga, Mahela and a very good batting line up. Once we had that belief that we could defend the runs. It always makes your job easier when you have Andre Russell, Darren Sammy, Kieron Pollard - some of the best fielders in the world - in one team. I'm a bit on the older side so I wouldn't add my name to that. It's good to be on a team that has such good athletes. It makes all our jobs easy."

West Indies' total had been set up by a rapid 62-run opening stand between Johnson Charles and Andre Fletcher. West Indies' innings slowed down considerably after their demise, but their hitting had already done plenty of damage, Sammy said.

"Today Malinga hit a lot of his yorkers and so did Kulasekara," Sammy said. "They bowled really well at the end of the innings. The work done by Charles and Fletcher at the top gave us that cushion - even if they bowled some good overs."

Bravo also contributed with the bat, hitting 31 off as many deliveries, before Denesh Ramdin provided a decent finish, making 34 not out off 22 balls. West Indies made only 34 runs in the last five overs of their innings, but death-over fireworks were not necessarily required in this match, Bravo said.

"In this format not all the time do you need to go for the big shots and score in excess of 130-140 strike rate. The conditions dictated how I played. We had a very good start. My role then became the anchor role and allow others to play around me. It would have been silly to let the ego get the better of me and try and score at 130-135 strike rate. That was not required at that point in time. Denesh' innings was very important. It gave us momentum. It wasn't a 190-200 wicket."
