Ireland batsman Ed Joyce has his sights set on a historic Twenty20 series win over West Indies when the sides reconvene at Sabina Park on Friday.
The Irish upset the reigning World T20 champions with a six-wicket success in Jamaica on Wednesday.
Should Ireland win, it would be a first series win over full member opposition.
"The way we played in the first game proved to the younger players that we can beat the world champions, which will give us huge confidence," he said.
Joyce, 35, hit 40 not out to see his side past the hosts' total of 116.
The victory brought back memories of the famous St Patrick's Day defeat of Pakistan on the same ground at the 2007 World Cup and Joyce is dreaming of another landmark for Irish cricket.
"It's absolutely possible," he said.
"It would be lovely to win 2-0, especially as we're probably a slightly better 50-over side than a 20-over side.
"We came so close to beating Pakistan in a series last year and we've dominated the associate scene for a while so it would be nice to get a big win against a major cricket nation."
