Three undefeated Grade 1 winners, including likely favorite My Miss Aurelia, are among 18 fillies pre-entered for one of the most formful Breeders’ Cup races of recent years.

The Juvenile Fillies has been won by the favorite eight of the last nine years, a role likely to be held in 2011 by My Miss Aurelia, facile winner of the Grade 1 Frizette at Belmont Park. Steve Asmussen trains My Miss Aurelia, ridden last out by Corey Nakatani. The 3-for-3 filly will try to stretch her speed two turns against two top fillies proven at a route.

LOUISVILLE, Ky. – Trainer Bisnath Parboo and his extended family have spent the last 15 years watching American’s greatest horse race, the Kentucky Derby, from the infield at Churchill Downs. But when the entire clan return to Churchill for next week’s Breeders’ Cup, they will have some of the best and most expensive seats in the house.

Even though a number of leading candidates recently dropped out of consideration for the Grade 2, $1 million Breeders’ Cup Juvenile Fillies Turf, the race still ended up drawing 22 pre-entries Monday.

“They tend to come out of the woodwork for this race,” said Josh Christian, director of racing for Breeders’ Cup.

Off a gaining fifth in the Grade 1 Jockey Club Gold Cup and a first-place finish (he was subsequently disqualified from the purse money) in the Greenwood Cup two starts back, A. U. Miner figures to be the favorite over 12 other pre-entrants in the Grade 2, $500,000 Breeders’ Cup Marathon going 1 3/4 miles, the first Breeders’ Cup race on the Saturday Breeders’ Cup card.

A. U. Miner was moved up to third in last year’s Marathon, which was won in a 10-1 upset by Eldaafer. Eldaafer is back to defend his title, but currently is not in as good a form as he was in this time last year.

Top Irish trainer Aidan O’Brien will be well represented in the $1 million Breeders’ Cup Juvenile Turf, even though he didn’t enter Power, who captured a Win and You’re In race in Ireland. O’Brien pre-entered Daddy Long Legs, Wrote, and Learn in the Grade 1 race, but the first preference for Group 2 winner Daddy Long Legs is the Grade 1 Juvenile on the dirt.

Although 15 horses were pre-entered on Wednesday in the Breeders’ Cup Ladies’ Classic, the final field drawn Monday for the Nov. 4 race at Churchill Downs figures to be considerably smaller, since several runners are likely to go in other races.

Of the 15 horses, six were also pre-entered in other races, including Havre de Grace, who is expected to face males in the Breeders’ Cup Classic on Nov. 5. Havre de Grace, though, will be allowed to enter both races, since they are run on different days.

When the six-furlong Juvenile Sprint was added to the Breeders’ Cup schedule this year – swelling the number of races to 15 – it was expected to serve as an alternative race to its other 2-year-old races, all of which are contested around two turns.

Lightly raced and speed-oriented juveniles were essentially the target market, and when pre-entries were announced Wednesday for the $500,000 Breeders’ Cup Juvenile Sprint, that was just what the race attracted.

Wednesday’s 16 pre-entries for the Breeders’ Cup Juvenile drew few surprises, save one: Dullahan, the Grade 1 Breeders’ Futurity winner who was pre-entered in both the Juvenile and Juvenile Turf, had his first preference announced as the Juvenile Turf.

Although his connections had stated he was under consideration for both races, Dale Romans, trainer of Dullahan, seemed to be favoring the Juvenile in comments made over past couple weeks.

LOUISVILLE, Ky. - And then there were twelve.

There were only 11 names on the list when pre-entries for the $1.5 million Breeders’ Cup Sprint were released late Wednesday morning, but that list grew to an even dozen less than two hours later after it was discovered that Trappe Shot’s name was omitted from the potential field due to a clerical error made by the Breeders’ Cup.

Switch was among the earlier arrivals at Churchill Downs, having shipped here shortly after running third as an odds-on favorite in the six-furlong Thoroughbred Club of America Stakes on Oct. 8 at Keeneland. Trainer John Sadler has been here to personally oversee the filly’s progress as she tries to improve on her runner-up finish in the 2010 Breeders’ Cup Filly and Mare Sprint.
