ARCADIA, Calif. - Walk In Marrakesh, second in the Grade 1 Natalma Stakes at Woodbine in September, will not start in the Friday’s Grade 1 Breeders’ Cup Juvenile Fillies Turf at Santa Anita, trainer Ignacio Correas said on Monday.

“She’s not as good as we want her to be,” he said. “She won’t be entered.”

Correas said Walk In Marrakesh “was tired after her plane trip” last week.

Blue Chipper will make some history on Saturday when he starts in the Grade 1, $1 million Breeders’ Cup Dirt Mile at Santa Anita. The 4-year-old son of Tiznow, who has won his last six starts by a combined margin of 45 1/4 lengths, is based at Busan Racecourse in South Korea.

“He’s the first horse to represent Korea in the Breeders’ Cup,” said Seungho Ryu, general manager of the international department of the Korea Racing Authority.

ARCADIA, Calif. – Hog Creek Hustle fits the underdog role well. After winning the Grade 1 Woody Stephens at Belmont Park at 18-1, the Overanalyze colt missed winning the Grade 1 H. Allen Jerkens at Saratoga by a few inches, this time at 10-1.

Triple Crown winner American Pharoah rolled home in the 2015 Breeders’ Cup Classic to end his racing career in style. But in some ways, his story was just beginning. Soon thereafter he arrived at Coolmore’s Ashford Stud in Kentucky where he would attempt to replicate himself.

And while American Pharoah was dominant on the racetrack, he faces a strong group of rival freshman sires as he begins to construct his legacy.

Street Sense won the Breeders’ Cup Juvenile in 2006 and then went on to become the first winner of that race to take the following year’s Kentucky Derby. This week in the Breeders’ Cup, his son Maxfield will try to put himself on the road to the Juvenile-Derby double, and his McKinzie will try to do something Street Sense couldn’t.

There are plenty of million-dollar questions on the Breeders’ Cup program – and some of them involve just who the attendees for Spendthrift Farm might be cheering for the loudest.

ARCADIA, Calif. – Mongolian Groom, a 25-1 winner of the Awesome Again, isn’t the only horse who earned his way into the Breeders’ Cup Classic with a big upset in a Grade 1 last month.

Math Wizard won the Pennsylvania Derby at 31-1, after which trainer Saffie Joseph Jr. and the owners of the 3-year-old Algorithms colt decided to try to stun the racing world again.

ARCADIA, Calif. – An intriguing showdown between Sistercharlie and Magical will not take place in Saturday’s $2 million Breeders’ Cup Filly and Mare Turf as Magical was diagnosed with a temperature Monday morning and did not ship to California.

Trainer Aidan O’Brien told The Racing Post that Magical would be retired.

“She has been an unbelievable mare,” O’Brien told the publication. “She was so game, so consistent and so classy.”

ARCADIA, Calif. – Three years have passed since Santa Anita last hosted a Breeders’ Cup. This year, the racing environment changed.

From a handicapping perspective, the biggest change this autumn is the main track. The surface is deep, heavy, and slow. Horseplayers wagering on 2019 Breeders’ Cup dirt races must consider the possibility the slower surface will influence results.

ARCADIA, Calif. – You could call him “Pinto Bean” and it would fit, but then nobody would call their top-class racehorse anything like that, so trainer Luis Carvajal Jr. settled on “Little Rocket.”

If he could limbo a little, Imperial Hint, 6, might walk clean underneath the largest Thoroughbreds. Out on the racetrack he just runs them over.

He’s not just small, he’s unusual looking, a bowling ball of a being, short legs poking out of a fullback’s torso so layered with muscle Imperial Hint looks almost as wide as tall.
