Owner Gerry Harvey says his smart mare Royal Descent might be the best he's ever raced Royal Descent smashes her rivals in the ATC Australian Oaks in the autumn. GERRY Harvey has owned hundreds of horses  so its a pretty good rap when he says Royal Descent could be the best hes ever raced. "Potentially she is the best horse I've ever had,"" said the Harvey Norman boss, whose top mare resumes at Warwick Farm tomorrow. We're only taking it one race at a time, but ideally I'd love to see her reach the Caulfield Cup and Cox Plate. At this stage the Melbourne Cup isn't in my head. I don't know how good Royal Descent is at this stage. This will only be her second preparation, and you can only hope she makes enough improvement to be a superstar horse. We'll find that out in the next two or three runs. Royal Descent wowed punters in the autumn when she smashed her rivals by a widening 10 lengths in the ATC Australian Oaks (2400m). What made the effort all the more remarkable was the fact it was only her first campaign. Harvey has raced some top-shelf horses over the years, including Gypsy Kingdom, Best Western, Fashions Afield, Lotteria, and more recently Group 1 winners Aloha and Mrs Onassis. But Royal Descent will trump all of them if she can make the tough transition to open company this spring. The TAB has listed her a $13 second favourite behind Fiorente and Jet Away in the Caulfield Cup, while she's a $31 hope in the Cox Plate. Harvey said Royal Descent would have her work cut out tomorrow in the Toy Show Quality (1300m), especially being forced to lump 59kg - and concede 5kg to the likes of No Looking Back and last-start winner Hidden Kisses - as well as a wide barrier. It should be noted that history also hasn't been kind with not one Oaks winner in the past 25 years getting the cash when resuming in the new season. Gerry Harvey says Royal Descent will have her work cut out in the Toy Show Quality, especially being forced to lump 59kg. Trainer Chris Waller said he was keen to see if Royal Descent's brilliant Oaks triumph was a "fluke." "I'm still getting over how she won the Oaks so easily," Waller said. Whether it was a combination of her being good and all the others having an off day, I don't know. It was also an extreme track that day. We will soon find out this preparation. I know she could potentially be a very, very good horse, but she's still got a long way to go. She's laidback and very versatile, and for that reason she can be competitive over these shorter trips. I think she can win Saturday, but she's not wound up (to win). Meanwhile, Waller said of the six Warwick Stakes runners, Beaten Up and Hawkspur were the two who would finish closest to the winner. "I don't think any of them will win on Saturday - I think they can all win a Group race this preparation - but the two with the most upside would be Beaten Up and Hawkspur," Waller said. Waller opted against sending Beaten Up to Melbourne next week for a first-up run in the Group 1 Memsie Stakes, and wanted to keep his lightly-raced stayer in his Sydney backyard another few weeks.
