Chris Hayes made every yard of the running aboard Market Rally to secure an impressive success in the UAE 2000 Guineas at Meydan.
Trained by Dhruba Selvaratnam, Market Rally had finished fourth in the trial event last month but stepped up on that effort to easily account for the Marco Botti-trained Lazzam.
Hayes' positive attitude from the off paid dividends as he had them all in trouble turning into the straight, with the Charlie Appleby-trained Rouleau dropping away quickly to leave Lazzam as the nearest challenger.
He was well beaten by the winner, though, with fellow British raider, the Simon Dow-trained Hombre Rojo, keeping on for third.
Hayes said: "I felt like he was in third gear. The plan wasn't to make the running but he got a little bit fractious in the gates and I gave him a squeeze to just hold my position.
"That's the beautiful thing about riding for Dhruba, he didn't put me under any pressure and let me do my own thing. I let him coast in front and ideally he wants further.
"I can't stress enough how good a training peformance this is. I recommended the hood to be put on him last time and Dhruba decided to take it off him in his work and he just turned inside out since. All credit has to go Dhruba."
Doug Watson's Polar River extended her unbeaten run to three with a 13-length stroll in the UAE 1000 Guineas.
An easy winner of the Trial last month, she beat Saeed bin Suroor's Promising Run by just under five lengths that day, but significantly increased that margin this time. Pat Dobbs was the only rider still on the bridle turning into the straight and without visibly asking for an effort, his mount quickly put the race to bed.
The UAE Oaks on March 3 is next, while Watson also raised the possibility of a crack at the colts in the Derby before continuing her career in America.
Watson said: "That was pretty impressive. Pat said she was a bit green until he gave her a squeeze but she's got some turn of foot. She'll go for the Oaks now and then if she wins, I'm sure we'd take an invitation to the Derby.
"The owners have been very good to me and to be fair to the filly, I think she deserves the chance to further her career in the States."
Dobbs said: "She's exceptional, that turn of foot she has. Halfway down the back she doesn't give you much of a feel, she's lazy and green, but when I gave her a squeeze, she grabbed the bridle and took me there very easily.
"I don't know how much more there is to come as she wins her races very quickly and then just glides home. I wouldn't know what would happen if you gave her a wake-up call. She's very good."
There was drama on leaving the stalls in the Al Shindagha sprint as the hot favourite Marking dumped James Doyle on the dirt. That left the former Dermot Weld-trained Rich Tapestry to dominate under Gerald Mosse for Michael Chang.
A winner at the Carnival in 2014, he was also the first Hong Kong-trained winner in North America when he won a Grade One at Santa Anita in October 2014.
Mosse, riding his first winner at Meydan, said: "He made me very happy today - better late than never. He loved the dirt, he has natural speed and just played with them all the way round. He's a beautiful horse to ride but he's a totally different horse on dirt to turf."
Chang said: "He loves Dubai and he loves the dirt. He's better when he's in Dubai longer than just coming for one race, so I think he'll run on Super Saturday as well."
