Bach retained his unbeaten record when defying top weight in the Leopardstown 2,000 Guineas Trial Stakes this afternoon.
Michael Kinane elected to make all the running on the 11-10 winner, just shaded for favouritism by Dermot Weld's recent Curragh winner Legal Jousting, and that tactic proved decisive as the Aidan O'Brien-trained son of Caerleon ran on strongly to land the Listed contest by a head from his market rival.
'It was a good display by Bach because he would not have liked the ground and was giving weight to the other three runners. He comes back here next month for the Derrinstown Stud Derby Trial,' said O'Brien.
Bach's stablemate Tribal Drum opened his account by a head in the preceding European Breeders' Fund Maiden.
The 2-7 favourite had to be rousted by Kinane to initiate the O'Brien double as 7-1 chance Baladeur challenged persistently in the final furlong.
O'Brien also confirmed that Rossini would represent him at Newmarket on Thursday in the thehorsesmouth.co.uk Craven Stakes.
