Simon Miller believes Leoluck is poised to extend his winning sequence to three in the Westspeed 3YO Handicap (1650m) at Belmont today.
The Akhenaton gelding graduates to metropolitan level after setting Pinjarra alight with consecutive wins from his first two starts this campaign.
Leoluck comfortably accounted for Foxy Commander over 1500m on April 9 before determinedly holding at bay the fast-finishing Scotland The Brave in a 1600m contest last fortnight.
"The margin wasn't there but it was a super run," Miller said.
"He was set up to get run down and they couldn't get him.
"His work on Saturday morning was terrific and he should acquit himself well."
Leoluck will carry top weight of 59kg and jump from the widest gate in 11 for jockey Pat Carbery.
"There doesn't appear to be top end speed in the race," said Miller.
"He should get across comfortably and lead or sit outside the pacemaker."
The twitter.com/perthracing Handicap will see Cat Five step up to the mile for the first time in his nine start career.
Cat Five broke his maiden status at Pinjarra three starts back and then backed it up with a third to Can't Hartley Wait at Ascot.
Last fortnight he faded to finish sixth of eight to Divine Hero but there were excuses after a slow beginning from the barriers.
"He missed the start and it was game over from there," Miller said.
"The draw isn't ideal and unlike Leoluck it will be a difficult task to get across.
"It's an open race and I can't split about eight of them.
"Pat (Carbery) will have to weave his magic but he has done that before."
Miller advised Power Princess had pulled up well from her Adelaide campaign and would likely be entered for the Group 3 Roma Cup (1200m) on May 26.
