LOUISVILLE, Ky. &ndash; Owner Andrew Rosen hopes that Breeders&rsquo; Cup success runs in the family.\r\nTwenty-six years ago, Rosen&rsquo;s family won the first-ever Breeders&rsquo; Cup race when Chief&rsquo;s Crown took the 1984 Juvenile at Hollywood Park. Five years ago, Merv Griffin&rsquo;s Stevie Wonderboy won the 22nd Juvenile at Belmont Park.\r\nOn Friday, Rosen will send out Theyskens&rsquo; Theory &ndash; a half-sister to Stevie Wonderboy &ndash; in the $2 million Juvenile Fillies at Churchill Downs. The Juvenile Fillies, run at 1 1/16 miles over the main track, drew a field of 13 with no clear-cut favorite. A Z Warrior, winner of the Grade 1 Frizette at Belmont last month, was listed as the 7-2 morning-line favorite. Last year, in a 12-horse field, Blind Luck was sent off at 7-2, the longest-priced favorite in the history of the race. She finished third behind She Be Wild, a 7-1 shot.\r\nTheyskens&rsquo; Theory, named for clothing designer Olivier Theyskens's latest fashion line&nbsp;as well as Rosen&rsquo;s own clothing company Theory, is listed at 10-1 on the morning line. She is a daughter of 2006 Preakness and Travers winner Bernardini, who in his first crop has sired nine winners, including A Z Warrior.\r\nTheyskens&rsquo; Theory, trained by Brian Meehan, won 2 of 4 starts &ndash; all on turf &ndash; in Europe, including the Group 3 Prestige Stakes at Goodwood. In her most recent start, Theyskens&rsquo; Theory finished third in the Group 1 Fillies&rsquo; Mile at Ascot. Since her pedigree suggests she should handle the dirt, Rosen and Meehan opted for the Juvenile Fillies over the Juvenile Fillies Turf.\r\n&ldquo;After the Fillies&rsquo; Mile, Brian and I got together and thought she came out of the race so good and she really has been training good, maybe we&rsquo;d try the Breeders&rsquo; Cup,&rdquo; Rosen said. &ldquo;If you look at her pedigree, it suggests she&rsquo;s bred for the dirt more so than turf.&rdquo;\r\nFrankie Dettori will ride Theyskens&rsquo; Theory from post 2.\r\nRosen is hoping Theyskens&rsquo; Theory makes the same move forward from turf to dirt that A Z Warrior did from synthetic to dirt when she won the Grade 1 Frizette by 1 3/4 lengths at Belmont last month. A Z Warrior raced close to a strong early pace before opening up a four-length lead in midstretch and holding off a late run from R Heat Lightning.\r\nA Z Warrior, trained by two-time Juvenile Fillies winner Bob Baffert, will try to stretch her speed around two turns, something Baffert doesn&rsquo;t seem too concerned about.\r\n&ldquo;She looked pretty good going a mile, didn&rsquo;t she?&rdquo; Baffert said. &ldquo;It&rsquo;s another sixteenth of a mile, what the hell, right? She&rsquo;s maturing, she&rsquo;s got a great mind, professional.&rdquo;\r\nR Heat Lightning, who won the Grade 1 Spinaway at Saratoga, had a tough trip in the Frizette. She broke inward from the rail and was bottled up along the inside for a good part of the trip before finding running room late.\r\n&ldquo;I think we ran the best horse in the Frizette,&rdquo; said Todd Pletcher, who trains R Heat Lightning for Joyce Robsham. &ldquo;When she didn&rsquo;t break well, she put herself in a tough spot. What I did like, in spite of that and being covered up and having to wait for a long time, she showed a lot of determination the last eighth of a mile.&rdquo;\r\nTell a Kelly won the Grade 1 Del Mar Debutante by 4 1/2 lengths. The Debutante produced five next-out winners, including three who won Grade 1 stakes. Tell a Kelly finished second in the Oak Leaf as the 1-2 favorite in a race where her trainer, John Sadler, thought his filly moved a little early. Calvin Borel replaces Alonso Quinonez for the Juvenile Fillies.\r\nAwesome Feather is 5 for 5, with four stakes wins, including a dominant 8 1/4-length victory in the My Dear Girl Stakes at Calder on Oct. 16, her first time going long.\r\n&ldquo;We thought she&rsquo;d run good going long,&rdquo; trainer Stanley Gold said. &ldquo;Obviously, we&rsquo;re going against the best in her class. I feel confident she&rsquo;s going to give her best effort, and we&rsquo;ll see if her best effort is in tune with the competition.&rdquo;\r\nJoyful Victory was a debut winner going two turns at Delaware Park before running third in the Grade 1 Frizette, a one-turn mile, at Belmont. Trainer Tony Dutrow believes the two turns is a major plus for his filly, who is a daughter of Tapit.\r\n&ldquo;The biggest thing that led us to the Breeders&rsquo; Cup was the fact it&rsquo;s a two-turn race,&rdquo; said Dutrow, who trains Joyful Victory for Rick Porter&rsquo;s Fox Hill Farm. &ldquo;If it had been a one-turn race, I would not have brought it to my client.&rdquo;\r\nBelieve in A.P. won a two-turn maiden race by 12 3/4 lengths at Parx Racing near Philadelphia after floundering on turf in Saratoga.\r\nThere appears to be some speed in the field with Soundwave and A Z Warrior likely to be forwardly placed. Indian Gracey also would have figured up front but trainer Jerry Hollendorfer said Thursday that she would be scratched with a sore right front foot.\r\nDelightful Mary, Harlan&rsquo;s Ruby, Izshelegal, and Jordy Y round out the field.
