Rory McIlroy and Shane Lowry will represent Ireland at the 2020 Olympics in Tokyo, it's been confirmed this afternoon as the field for the men's golf competition was officially finalised.

The announcement of the 60-strong field came alongside news of more withdrawals, with former major champions Sergio Garcia, Louis Oosthuizen and Martin Kaymer were declining their invite.

The field was selected on the basis of the world rankings but with the proviso that no nation can select more than four golfers and no more than two if they are ranked outside the top 15.

Lowry, the reigning Open champion, who finished in a tie for 4th at last month's PGA Championship in Kiawah Island is currently ranked 18th, while four-time major winner McIlroy, who recently won the Wells Fargo Championship in Quail Hollow, is ranked 6th.

Neither player represented Ireland in Rio in 2016, citing concerns about the Zika virus, though both admitted to regrets afterwards. Seamus Power and Padraig Harrington represented Ireland in Rio, finishing in a tie for 15th and 21st respectively.

2017 Masters champion Garcia withdrew, citing qualification for the Ryder Cup as his priority while 2010 Open Champion Oosthuizen cited both family commitments and his focus on a strong FedEx Cup finish.

They join other high profile opt-outs such as Dustin Johnson, Tyrrell Hatton, Matt Fitzpatrick and Lee Westwood.

In Johnson's absence, the US team will consist of Bryson Dechambeau, Collin Morikawa, Justin Thomas and Xander Schauffele, with Patrick Cantlay as first reserve.

With Hatton and Fitzpatrick opting out, Great Britain will be represented by Paul Casey and Tommy Fleetwood.

US Open champion and new World No. 1 Jon Rahm is competing for Spain.

The men's competition will take place from 29 August-1 July, with the women's running from 4-7 August. Both take place at the Kasumigaseki Country Club.

The women's field will be finalised after the Women's PGA Championship next week but Leona Maguire and Stephanie Meadow look certain to represent Ireland for the second Olympics in a row, having finished tied-21st and tied-31st respectively last time out.
