Having led Europe to a comfortable win at Rome’s Marco Simone Golf Club in 2023, captain Donald stayed in post to guide them to a stunning victory on US soil at Bethpage Black, in New York, in 2025.
At Adare Manor, he could become the first captain to win three in a row and will be only the fourth captain to lead at three straight Ryder Cups after Ben Hogan, Sam Snead and Bernard Gallacher.
He says Harrington will form a key part of his backroom staff in his quest to make history.
“I’ve been around Padraig in many Ryder Cup team rooms, as a player, as a vice captain to his captaincy, and he’s been a vice captain before as well,” Donald said. “So he brings a wealth of experience.
“I do love the fact that there’s a connection. He understands the Irish crowds and all that goes with having a Ryder Cup in Ireland. I think it’s going to be very special for him.
“He’s loved in Ireland with what he’s achieved in the game, and that will only bring more energy to our team.”
It will be the first time the competition has been held in Ireland since 2006, when Harrington was in the European team that won 18½-9½ at the K Club, County Kildare.
“You wouldn’t want to miss out with it being in Ireland, so I’m very pleased,” Harrington added. “I think it will be a spectacular occasion and one of the great sporting events to be played in the country. The whole of Ireland will be behind it, watching it, enjoying it and living it.
“The fans are going to be fantastic, and I think the atmosphere will be second to none.”
In total, Harrington played in 25 matches across six Ryder Cups, winning 10½ points for Team Europe, while he also boasts 44 tournament victories across a glittering career.
He still plays on the DP World Tour and in major championships, most recently at The Open.
Since turning 50 in 2021, he has starred on the Champions Tour, including winning a record-equalling three US Senior Open titles.
