Arglass player Cormac Sharvin and Open Championship star Paul Dunne are among a record five Irishmen picked for this year's Walker Cup match.
Sharvin, 22, earns his spot in the Great Britain & Ireland side after winning this year's Brabazon Trophy.
Dunne, who is also 22, was joint-leader at the Open last month after 54 holes before finishing in a share of 30th.
Naas's Jack Hume, West Waterford's Gary Hurley and the Island's Gavin Moynihan are also in the 10-man team.
Great Britain & Ireland will be aiming to win back the trophy at Royal Lytham & St Annes after the USA earned a comprehensive 17-9 victory in 2013 at the National Golf Links of America in Southampton, New York.
Ireland's five-strong representation for the biennial match on 12-13 September beats the previous record of four team members in 1949 and 1951.
Sharvin said his selection for the Royal Lytham match was the "icing on the cake" after his impressive amateur season.
"I've played really well all season and it was nice to break through and win the Brabazon," added the 22-year-old.
"And playing in the Walker Cup is the best thing you can do in amateur golf if you are from Britain and Ireland."
Great Britain & Ireland's captain Nigel Edwards said that the selectors had faced "difficult decisions" in picking the team.
"But we believe we have selected the best players for the team and are very much looking forward to the match," added Edwards.
"We have selected a talented group of players who compete at the highest levels of amateur golf and, in some cases, have played in major championships and tour events.
"The Walker Cup offers these players a tremendous opportunity to display their abilities and gain invaluable experience of playing in international team competition."
