Breeders' Cup Juvenile Turf winner George Vancouver is the star name among 18 entries for the 2,000 Guineas Trial at Leopardstown on Sunday.
Aidan O'Brien's Henrythenavigator colt - mentioned favourably by the trainer after galloping at the Curragh last month - was third to Dawn Approach in the Dewhurst before travelling to America, where he ran out a decisive winner.
O'Brien has also entered Festive Cheer, Flying The Flag, Francis Of Assisi, Magician and the once-raced The United States.
Jim Bolger has started the season in red-hot fashion and has Trading Leather, Dewhurst runner-up Leitir Mor, Move To Strike and Alpinist to choose from.
Mick Halford's Dibayani, Tommy Carmody's Fort Knox, High Octane from John Murphy's yard and David Wachman's Fighter Squadron are other interesting contenders.
Richard Hannon's Moyglare winner Sky Lantern is one of 14 possibles for the 1,000 Guineas Trial.
O'Brien is again strongly represented, with Snow Queen, Magical Dream and Greek Goddess all entered.
Bolger's Bunairgead, John Oxx's What Style and Wachman's Hint Of A Tint all look promising types.
