David Wachman believes the step up to seven furlongs will suit Orchestra Leader in the Korean Racing Authority Tyros Stakes at Leopardstown.
The son of Van Nistelrooy got off the mark over six furlongs at Navan in mid-May after showing promise when sixth to Power on his debut over the same distance at the Curragh.
"He's fine and we're hoping he'll give a good account of himself. I think the trip will help him very much. This race will tell us more," said the County Tipperary trainer.
Orchestra Leader is owned by Sue Magnier, whose colours will also be carried by Vault. The Aidan O'Brien-trained colt made a winning debut at the Curragh, only to disappoint in a Group Two there on his only other start.
O'Brien also saddles recent Leopardstown winner Tenth Star in a seven-runner field.
Jim Bolger has declared Parish Hall and Cheerful Giver, while Jessica Harrington's Remember Alexander and Ken Condon's Strait Of Zanzibar complete the line-up.
