ARCADIA, Calif. – Jockey Martin Garcia was expected to be hospitalized overnight on Wednesday after being unseated in a morning workout at Santa Anita, according to his agent, Thom Mitchell.

Garcia was working Orca for trainer Ron McAnally when he was unseated while pulling up the 2-year-old filly.

Garcia struck his head in the fall, which prompted doctors to keep the rider in the hospital for observation, Mitchell said.

“They’re being cautious because it’s a head deal,” Mitchell said. “I talked to him. He’s groggy. I think he hit his head pretty hard.

ARCADIA, Calif. – Since Drayden Van Dyke won his first riding title at Del Mar on Sept. 3, he has celebrated his 24th birthday and won three stakes at Kentucky Downs and Los Alamitos.

On Friday’s first day of the autumn meeting at Santa Anita, Van Dyke has five mounts on the nine-race program and the job of trying to win his first riding title there.

“Hopefully, I can pick up where I left at Del Mar,” he said between workouts on Wednesday morning. “I hope to keep getting on the right horses.”

The Grade 1, $1 million Breeders’ Cup Dirt Mile will be run at a one-turn configuration for the first time since 2011 when it is renewed Nov. 3 at Churchill Downs. It’s an “intriguing” twist that makes the race a potential target for a vast cross-section of horses, trainer Al Stall Jr. said.

“They’re coming from everywhere,” he said.

Stall hopes C Z Rocket will punch his ticket to the Dirt Mile – expected to be led by Catalina Cruiser, an undefeated graded stakes winner at one turn and two – when he runs Saturday in the Grade 3, $100,000 Ack Ack at Churchill Downs.

LOUISVILLE, Ky. – Monnie Goetz will be on the ground, not astride her popular pony Harley, prior to the first race Friday at Churchill. Goetz will saddle Cedar Creek for the $10,000 starter allowance while taking a short break from her self-owned pony service, which accompanies most Churchill runners to the starting gate.

LOUISVILLE, Ky. – Chad Summers is poised to saddle a horse for a Churchill Downs race for the first time, but this is hardly his first visit to the historic track.

Summers, 33, has attended a half-dozen runnings of the Kentucky Derby since 2001, when he and his father and brother ventured as novice fans from their Long Island, N.Y., home to sit in the rafters of Sec. 325, high across from the quarter pole.

His vantage point, you might say, has improved substantially since then.

Glorious Empire, winner of the Grade 1 Sword Dancer Stakes on Aug. 25 at Saratoga, will spend the early weeks of autumn being prepared for the Breeders’ Cup Turf on Nov. 3 at Churchill Downs.

There will be no prep races, such as Saturday’s Grade 1 Joe Hirsch Turf Classic at Belmont Park, only regular exercise at trainer Chuck Lawrence’s base at the Fair Hill Training Center in Maryland. Lawrence and Matt Schera, who owns the 7-year-old gelding, considered the Hirsch, but think Glorious Empire will be better with a longer gap between races.

Three times in the last four years, champion trainer Chad Brown has walked into the winner’s circle after the Breeders’ Cup Juvenile Fillies Turf. With four victories, Brown is the winningest trainer in the 10-year history of the race, having also won the inaugural running at Santa Anita in 2008.

What do we know about the $1 million Breeders’ Cup Juvenile Turf with just five weeks until the 12th edition of the race? Not much.

North American 2-year-old turf form remains murky and it will be a couple of weeks before European horse folks sort out which juveniles will be pointed toward Churchill Downs, where the Juvenile Turf is contested over one mile on Nov. 2.

Accelerate this year already has taken down the Santa Anita Handicap, Gold Cup at Santa Anita, and Pacific Classic. His trainer, John Sadler, hopes to make it a grand slam of 1 1/4-mile races on Nov. 3 in the Breeders’ Cup Classic at Churchill Downs, victory in which would guarantee Accelerate an Eclipse Award as champion older dirt male.

“It’s why I’m here every day, even when I’m sick,” Sadler said this week at Santa Anita as he trudged through the stable area while fighting off a cold. “The horse is so solid. You just hope to continue to have good luck along the way.”

The turn of the season to fall traditionally signals the time for 3-year-olds to graduate to facing their elders. That collision course looks especially meaningful in the $2 million Breeders’ Cup Distaff – this year restored to the Saturday program – which will feature a stellar group of 3-year-old fillies, led by Kentucky Oaks winner Monomoy Girl.
