INGLEWOOD, Calif. - The cast of fillies and mares who will challenge Zenyatta in Saturday's $250,000 Lady's Secret Stakes at Hollywood Park includes a mare who gave her a test in the Grade 1 Clement Hirsch Stakes at Del Mar in August and four others who face the toughest challenges of their careers.

Zenyatta will be heavily favored to extend her unbeaten streak to 19 races in the Grade 1 Lady's Secret, a race she won in 2008 and 2009. Zenyatta will be ridden by regular rider Mike Smith and has drawn post 5 in a field of six.

A memorial service for jockey Alan Cuthbertson will be held at 11:30 a.m. Friday in the backstretch restaurant at Hastings.

Cuthbertson was 63 when he died after a lengthy battle with lung cancer Sept. 6. Cuthbertson was the leading rider at Assiniboia Downs in 2006, 2007, and 2008.

Not two hours after Rachel Alexandra was retired Tuesday, Fair Grounds renamed one of its major races in her honor.

The Silverbulletday Stakes, the New Orleans’ track’s prep race for the Fair Grounds Oaks, and scheduled for Feb. 19 in 2011, now will be called the Rachel Alexandra Stakes. The former Tiffany Lass Stakes, scheduled for Jan. 22 next year, has been renamed the Silverbulletday Stakes. Tiffany Lass, winner of the 1986 Kentucky Oaks, is out of the Fair Grounds stakes cycle.

STICKNEY, Ill. – Hawthorne Race Course begins its fall-winter meeting Friday hoping for the best, but planning for the worst.

INGLEWOOD, Calif. – Every day, year after year, through a Presidential election, two Olympics games, and a few Super Bowls, life at the barn of trainer John Shirreffs has been warmed by one constant, Zenyatta. Her racing career began in November of 2007, and, now 18 starts later, she remains the embodiment of perfection.

It has been five months since Eskendereya was retired from racing a week before he would have been favored in the Kentucky Derby, and his owner, Ahmed Zayat, still hasn’t gotten over it.

“I’d be lying if I said otherwise,” Zayat said Wednesday by phone from Egypt.

But with each new crop of 2-year-olds that arrives, the potential is there for another superstar to emerge. And while Zayat has not raced all of his 2-year-olds, two have displayed serious potential and could be contenders for this year’s Breeders’ Cup Juvenile Nov. 6 at Churchill Downs.

INGLEWOOD, Calif. – Leaving New York had a three-race campaign at Del Mar this summer that covered just about every kind of a race a maiden winner could try – a claimer, an optional claimer, and a Grade 1.

Leaving New York was sixth in a $25,000 claimer, won the optional claimer, and was fourth in the Grade 1 Pat O’Brien Stakes. For Friday’s seventh race at Hollywood Park, Leaving New York starts in an allowance race over 6 1/2 furlongs, which trainer Carl O’Callaghan hopes will lead to a start in the $100,000 California Cup Sprint here Oct. 30.

ARLINGTON HEIGHTS, Ill. – Betting on horse racing all over the country has declined this year, but for some reason, Arlington Park took the worst of things during its 2010 meet that ended Sunday. While ontrack business held relatively steady, out-of-state handle on the Arlington product cratered, and average daily all-sources handle went into free fall, dropping by almost 30 percent.

ANDERSON, Ind. – Easily the biggest draw in the history of Thoroughbred racing in Indiana will be at Hoosier Park on Saturday when Lookin At Lucky prepares for the Breeders’ Cup Classic by taking on eight other 3-year-olds as a heavy favorite in the Grade 2, $500,000 Indiana Derby.

Lookin At Lucky, winner of the Preakness and Haskell and the clear-cut leader in the North American 3-year-old division, was assigned post 6 when entries were drawn Wednesday for the 1 1/16-mile Indiana Derby. Martin Garcia has the mount for trainer Bob Baffert.

Headed by Blind Luck, the nation’s leading 3-year-old filly, nearly all of the top contenders for this year’s $2 million Breeders’ Cup Ladies’ Classic will be in action Saturday.

Blind Luck departed Southern California on Wednesday for Philadelphia, where she will compete in the Grade 2, $750,000 Cotillion Stakes at Parx Racing. Four other 3-year-old fillies are entered in that race, though Bonnie Blue Flag also is entered in the Grade 1, $350,000 Beldame Stakes for older fillies and mares at Belmont Park.
