Aidan O'Brien saddled the first three home in the Juddmonte Beresford Stakes at the Curragh as Capri completed a hat-trick.
The Galileo colt was made to work hard but ground it out well to give his handler a sixth straight victory in the Group Two contest, and a 16th in total.
Escape Clause and Exemplar took the six-strong field along until the latter went on, but his stablemate Capri soon ranged alongside under Ryan Moore and the 8-11 shot asserted to score by three-quarters of a length.

The four-year-old bounced back from a short-head defeat in the Park Stakes at Doncaster to take the Group Three event, making most of the running and keeping on well to hold Flight Risk by three-quarters of a length.

Patrick Mullins partnered the Mick Winters-trained Theos Well (8-1) to a comfortable three-and-a-quarter-length success from Pivot Bridge in the Manguard Plus Amateur Riders Derby (Q.R.)
