Dream Castle got on top in the last half-furlong to complete a hat-trick of victories in the Group One Jebel Hatta.
Christophe Soumillon delivered the Saeed bin Suroor-trained five-year-old with a well-timed run in the centre of the course to score by a length and a quarter.
The gelded son of Frankel showed a devastating turn of foot to make it a clean sweep at Meydan after victories on January 3 and 24.
Dream Castle had the Appleby-trained duo of Wootton and First Contact back in second and third place respectively.
Bin Suroor said: “Nine furlongs is a good trip for him. The plan now is to take him for the Dubai Turf.
“I think in the past we thought he was a sprinter, but I believe his trip is nine furlongs plus. He is a different horse, more relaxed and that gives him a chance to run well.”
Soumillon said: “The race went well for us. We had a nice pace. When I saw I was behind Wootton, I was very confident, because I knew he was going to take me quite far.
“When I asked him to go, he really quickened sharply. When I hit the front, he was looking around for a while. He’s a really different horse compared to last year, when he was a colt.”
