Charlie Appleby has ruled out a tilt at the Dubai World Cup with Tryster ahead of his return to the turf at Meydan on Thursday.
The Godolphin-owned five-year-old is unbeaten on the all-weather after six starts in Britain, claiming notable victories in the Winter Derby and the Coral Easter Classic at Lingfield last spring.
He made a successful return from a break at Chelmsford in September and is a best-priced 25-1 for the world's richest race.
But having failed to sparkle on the dirt since arriving in Dubai, connections have changed tack and he is back on the grass for the Group Three Dubai Millennium Stakes.
Appleby said: "We brought him out here with the idea of running him in the Al Maktoum challenges on the dirt, but when we've worked him on it, hedoesn't have the same stride pattern or turn of foot he's shown on synthetic surfaces.
"He's also a hold-up horse and that style of racing isn't really suited to running on the dirt out here.
"He's not going to win a Dubai World Cup and we don't want to give him a bad experience on the dirt, getting a lot of kickback, as it could ruin him,which is why we've decided to go back to the grass."
Tryster's record on turf is less inspiring as he has managed just one success - in a Brighton maiden in July 2014 - from four starts.
The son of Shamardal finished a well-beaten last of five in the Brigadier Gerard Stakes at Sandown last May, but Appleby is keen to give him another chance.
He said: "People will question running him on the turf, but he won his maiden on it and was running a good race when he went wrong at Newmarket as a three-year-old.
"He got injured that day, which is why he had to have the time off and came back on the all-weather at the start of last year.
"We're putting a line through his run at Sandown as it was a small field and a steadily-run race. The horses he was running against were also of a high calibre.
"He's in good order and it's a big field on Thursday, so hopefully he'll get the good gallop he wants and we'll see what happens."
Tryster will be partnered by William Buick as he faces nine rivals over a mile and a quarter.
Saeed bin Suroor's three-time course winner Haafaguinea and Al Rashidiya third Earnshaw are among his opponents.
There is plenty of British interest elsewhere on the card, with Brendan Powell's stable star and Dubai specialist Dark Emerald a major contender for the opening Range Rover Handicap.
A host of familiar names go to post for the five-furlong Jaguar F-Type Handicap, including Mick Halford's Irish challenger Toscanini, the Jeremy Gask-trained veteran Medicean Man, Rae Guest's Mirza and the Robert Cowell-trained pair of Speed Hawk and Green Door.
Toscanini heads the weights on his first competitive start since finishing fourth in a Listed event at the Curragh last October.
