Irishman Harrington named his selections a few hours after England's Lee Westwood, Matt Fitzpatrick and Tyrrell Hatton had sealed their spots in the 12-man team at the European Tour's BMW PGA Championship along with Austrian Bernd Wiesberger who will make his debut.

Spanish World No.1 Jon Rahm, Northern Irishman Rory McIlroy, England's Paul Casey and Tommy Fleetwood plus first-time participant Viktor Hovland of Norway had already secured spots on the team for the September 24-26 event at Whistling Straits, Wisconsin.

The Ryder Cup, a biennial team competition between the U.S. and Europe, was postponed last year because of the COVID-19 pandemic.

Europe are defending champions after a seven-point rout at Le Golf National near Paris in 2018.

Garcia, Europe's all-time leading Ryder Cup points scorer, and the inspirational Poulter, nicknamed ‘The Postman’ for his knack of delivering crucial points, were hardly a surprise.

That left Harrington with the tough choice between 2019 Open champion Lowry, who failed to land an automatic spot, and England's Rose, a veteran of five Ryder Cups.

Rose would have had to win the BMW PGA Championship at Wentworth on Sunday to seal one of the nine automatic places but finished in a tie for sixth after a storming final round.

Rose eagled the 18th in a final round of 65 to finish in a tie for sixth, but that was not enough.

"It was incredibly difficult with JR," Harrington said.

While admitting Rose's omission was tough, Harrington believes Team Europe is as strong as it has ever been.

"I am absolutely thrilled with my team. With all of our picks we have the strongest 10, 11 and 12 we've ever had," Harrington said.

On selecting Englishman Poulter, who is undefeated in singles matches in his six previous appearances, Harrington said: "He lifts himself, he lifts his partners, he lifts the team ... That's so important to the team.

"I know I have players who are good enough to deliver and Poulter is at the heart of our team."

On his 10th appearance, Garcia, who has contributed 25.5 points as part of six triumphant European teams, said: "It feels amazing. It's been a good year but I fell just a little short of making it by myself but I'm happy to have the confidence of the captains."

Ireland's Lowry, one of three European rookies, said it was a relief to get a pick after falling short of earning a place on merit.

"It's amazing, it's been a career-long goal to get to the Ryder Cup," he told Sky Sports.
