Ireland go into their three one-day internationals against Zimbabwe in the hope of defending their lead over their opponents in the world rankings.
Ireland are currently ranked 10th and Zimbabwe 11th, with the Irish holding a two-point advantage over their rivals.
Kevin O’Brien is set to make his 250th appearance on Friday after recovering from a hamstring injury which kept him out of August’s defeat by Australia.
Zimbabwe fell to a 2-1 series defeat by Pakistan in Harare last week.
They are keen to re-establish their place in the world’s top 10 but the Irish could extend their advantage as much as 14 points with a 3-0 victory, or six points if they take the series 2-1.
Conversely, a Zimbabwe series win would move them above Ireland, while the tourists would drop below Afghanistan into 12th place if they lose 3-0.
