Uxmal provided trainer Joseph O'Brien with back-to-back victories in the Queen Alexandra Stakes that brought Royal Ascot 2024 to a close.
The Owning Hill handler saddled Dawn Rising to win the extended two-mile-five-furlong marathon 12 months ago and the JP McManus-owned gelding was in the field again as he looked to defend his crown.
Ridden by William Buick, Dawn Rising led his rivals into the home straight, but his stablemate and 2-1 favourite Uxmal was going ominously well in his wing mirrors under Dylan Browne McMonagle and after hitting the front he never looked in any real danger of being caught.
The admirable veteran Run For Oscar, a luckless third last year, again made late gains to pick up minor honours, but Uxmal was well on top as he passed the post with five lengths in hand.
O'Brien was saddling his fourth Royal Ascot winner, but it was a first for the rider.
