Harrington will remarkably become the third Irish-born European Captain in the past four Ryder Cup's after Paul McGinley captained the victorious 2014 European Team at Gleneagles and with Darren Clarke captaining hapless 2016 side that lost at Hazeltine.
Lawrence Lyons, spokesperson for BoyleSports said: "Padraig Harrington says he has been encouraged by the support for him as the new Ryder Cup captain but it hasn't done enough to increase the confidence of punters".
That's according to the Rathfarnham club captain, Brendan King, who says the three-time Major victor has a place of honour in their clubhouse.
We take a look at five candidates who could captain Team USA's next bid for Ryder Cup glory.
"It is a tremendous honour to be named Ryder Cup Captain and I am relishing the next 20 months as we work towards Whistling Straits and Europe's defence of the trophy", said Harrington.
"It's not something I take on without a certain amount of trepidation", he told a news conference at the European Tour's headquarters.
"I didn't really know much of what was going on".
Europe were beaten 17-11 on their last attempt to retain the trophy in the United States and, while McGinley believes it will be a tall order to do so this time around at Whistling Straits, he believes Harrington should have plenty of reason for encouragement.
It remains to be seen who will captain the U.S. in 2020, although Fred Couples and Steve Stricker are thought to be among the leading candidates to follow in the footsteps of Jim Furyk.
"It's something I did think long and hard about", he added.
Word in the media tent was that Thomas Bjorn had made obvious a desire for his vice-captains to steer clear of casual interaction with anyone outside Europe's team room. Making his 13th Ryder Cup appearance as a player is more likely to be his focus.
It's vital to serve an apprenticeship as a vice-captain so that, when you get your turn in the top job, you know every detail and you also know how important your backroom team is.
Europe have dominated the Ryder Cup in the modern era, winning nine of the last 12 matches.
"I think the standard of golf on the European Tour and the players we have on tour is going to ensure that". "It seems to be the right time and place for me in my career". "I'm very much looking forward to taking on this role".
"Steve's a solid bloke", Harrington had said in October.
"You know you've got a game when you're playing against him".
"You know when you're going up against a guy like that that he is mentally tough and strong".
"It is daunting because you want to do a good job". He's as straight as they come.
