Aidan O'Brien relies on Bach in the Leopardstown 2000 Guineas Trial Stakes at the Dublin track on Sunday.
Bach, winner of both his starts at two, has not been seen out since landing the Chesham Stakes at Royal Ascot.
The Ballydoyle colt faces just three rivals Golovin, River Sounds and Legal Jousting.
And the last-named's trainer Dermot Weld said: "He's a good horse and I'm very pleased with him."
King Of Kings' sister Amethyst and Bells Are Ringing represent O'Brien in the Leopardstown 1000 Guineas Trial 30 minutes later.
Amethyst, third to Halland Park Girl in a Doncaster Listed race last October, is the likely favourite for Sunday's race with Jim Bolger's Aretha also sure to be well supported in the eight-runner contest.
