Kevin O'Brien is hoping that Ireland's aggressive approach to their opening T20 victory over world champions the West Indies can create the path towards a historic series win in the Caribbean.

Having pushed their hosts, but ultimately coming up short in the preceding one-day series, Ireland began the shorter-form sequence with a superb victory in Grenada on Wednesday.

Key to the victory was the opening stance between O'Brien and fellow attacking batsman Paul Stirling, who blasted the home attack with a record-breaking 93-run powerplay.

Ireland averaged over ten runs an over en route to their winning total of 208 as the West Indies came up four runs short from their allocation.

The team have now arrived in Basseterre, St Kitts ahead of the second game of the three-match T20 International series on Saturday and O’Brien is hoping that Ireland can build on their opening win.

"We are feeling very good. It was a fantastic team performance, and all the squad put in a big effort to get over the line," said O'Brien.

"To go ahead 1-0 in an away series against one of the best teams in the world is special. We can create history in the next two games by winning an away series.

"To win an overseas series is very difficult and it’s for that reason, at training today, the win in game one will be forgotten and we will be focused for Saturday’s game."

O’Brien was elevated to open the innings with Paul Stirling in T20s last year and the partnership seemed to click immediately, with the two batters finishing the calendar year number one [Stirling] and number two [O’Brien] in run-scoring in T20Is worldwide.

"I have no idea," said O'Brien, when asked what was making that combination work so well.

"We are both aggressive batsmen, so it comes quite naturally to us to play that way.

"I think when you play the best in the world, our approach is that you won’t beat them if you don’t stand face-to-face with them and throw some punches.

"So the best way for us to beat teams is to play that way and take the game to the opposition.

"It also helps to get you up for the challenge when there is such a passionate crowd, like in the Caribbean.

"The atmosphere the local fans create – they have a love of cricket and they like to watch cricket played the right way. 

"They want to see players entertain them on the field, they want fours, sixes, wickets, catches. The party atmosphere in the stadiums is something that is not experienced anywhere else in the world."

O’Brien’s score of 48 from 32 balls was his highest score on tour so far, and the big-hitting batsman admits that he embraces the Caribbean conditions and attempts to play his natural game.

"It’s good to be back on tour and it’s been a competitive and hard-fought series against a good Windies side so far.

"The conditions are obviously different from where we played most recently, but you just have to adapt.

"On the whole, I try to play with the same basic way I have always played - to be positive and take the game to the opposition bowlers - but at the same time I’ve tried and be proactive towards what the conditions and the game situation presents me with every time I go out to bat."
