For the first time since the 1972 Olympics in Munich, Ireland will have not one but two swimming relay teams at the Olympic games in Toyko.
Swim Ireland performance director Jon Rudd and National Coach Ben Higson took a chance in sending the Men's 4x100 medley relay and the Men's 4x200 freestyle relay squads to the recent Europeans where they set new Irish records.
Currently, both squads are ranked inside the top-eight in the world rankings
The criteria for selection to the games for relays, however, was that the top-12 from the World Championships automatically qualified - leaving four spaces to make up 16 nations.
Ireland's two squads earned a spot on the plane to Toyko as the 4th best of the wildcard nations.
Shane Ryan, Darragh Greene, Mona McSharry and Daniel Wiffen had already pre-qualified for individual events.
Now, the Men's 4x100 medley squad consisting of Ryan, Greene, Brendan Hyland and Jack McMillan will line up on the blocks in Japan.
And they will be joined by McMillan, Jordan Sloan, Finn Mc Geever and Gerry Quinn, the Irish quartet who will contest the Men's 4x200 freestyle relay next month.
There is still one more opportunity for those Irish swimmers who are close to the Olympic qualifying time to add their name to the growing list bound for Tokyo when Swim Ireland host their final qualifying meet at the NAC in Dublin from the 24-26th of this month
