Drumbeat added further depth to Aidan O'Brien's Classic battalion for next year in earning quotes of 14-1 for the Derby after landing the Criterium de Saint-Cloud at the Paris track.
The Wootton Bassett colt - wide-margin winner of the Zetland Stakes at Newmarket last time out - looked short of room at a crucial stage of the race under Ryan Moore, but burst through a gap to lead approaching a furlong and a half out.
From there he stayed on too strongly for stablemate Shakespeare and Christophe Soumillon, the pair two lengths back in second with Joseph O'Brien's Jesus Green a further length away in third.
The 9-10 favourite was delivering a seventh win in the race for O'Brien, but a first for Moore after wins for Soumillon aboard Pierre Bonnard 12 months ago and Los Angeles in 2023.
