ARCADIA, Calif. – Arrogate had an easy morning Tuesday at Santa Anita, with a half-mile work in 50 seconds under jockey Rafael Bejarano as he continues his preparation for the Breeders’ Cup Classic on Nov. 4 at Del Mar. He galloped out five furlongs in 1:03, and six furlongs in 1:16, according to Santa Anita’s clockers.

Canterbury-based Amy's Challenge, who has run the fastest Beyer Speed Figures of the year for a 2-year-old filly, has been ruled out of Keeneland's Grade 1 juvenile stakes this weekend after an episode of tying up, a condition causing severe muscle cramping, trainer Mac Robertson said Tuesday morning.

The seventh race at Parx on Monday was declared a no contest after a one-horse spill left jockey Mychel Sanchez lying unconscious in the center of the turf course on the first turn of the 1 1/16-mile race. The outriders waved the remaining eight runners in the field to a halt in the stretch.

Sanchez was aboard Shake Things Up for trainer Jorge Navarro in the $16,000 claiming race. Shake Things Up was racing in third position entering the first turn when he appeared to break down, although it is possible he may have clipped the heels of Vinceremos.

Voodoo Song, who won two races in five days as part of his four-win Saratoga meet, could wheel back in a week in Saturday’s Grade 3, $500,000 Hill Prince Stakes at Belmont Park, trainer Linda Rice said Monday.

Voodoo Song finished second, beaten three-quarters of a length by Just Howard, in the Grade 3, $200,000 Commonwealth Derby last Saturday at Laurel.

“It is a possibility only because how often do you get to run for $500,000 in your backyard?” Rice said. “And, he’s a 3-year-old and there are only a few straight 3-year-old grass races left this year.”

At least 10 horses are expected for Saturday’s Grade 1, $500,000 Champagne Stakes for 2-year-olds at Belmont Park.

The latest to join the fray is Kowboy Karma, runner-up in the Sapling Stakes, who worked five furlongs in 59 seconds Monday morning at Delaware Park. Trainer Larry Jones said he put a filly a few lengths in front of Kowboy Karma and the colt finished a little bit in front at the wire.

ELMONT, N.Y. – Good Samaritan will be equipped with blinkers for the first time when he runs in Saturday’s Grade 1, $750,000 Jockey Club Gold Cup at Belmont Park, trainer Bill Mott said.

Good Samaritan has worked a few times in blinkers, and Mott likes the impact they’ve had on the 3-year-old son of Harlan’s Holiday. Good Samaritan had his final work for the Gold Cup on Monday, going five furlongs in 1:03.59 over the Oklahoma training track in Saratoga, with a final quarter in 24.60 seconds, according to Saratoga clocker Dave Norton.

Evangeline Downs in Opelousas, La., will open a 46-date meet for Quarter Horses on Wednesday night. The season runs through Dec. 19.

Girvin, who earned a berth into the $6 million Breeders’ Cup Classic with his win in the Haskell Invitational in July, has wrapped up his season, trainer Joe Sharp said Monday. Girvin last raced on Sept. 24, finishing fifth in the Grade 3, $400,000 Oklahoma Derby at Remington Park.

Bird Song, a two-time graded winner of $512,707, has been retired after exiting his last race, the Sept. 23 Kelso at Belmont Park, with what trainer Ian Wilkes described as a minor injury.

Bred and owned by the Marylou Whitney Stables, Bird Song, a 4-year-old colt by Unbridled’s Song, won the Grade 3 Fred Hooper and Grade 2 Alysheba earlier this year.
