Flores sidelined for six weeks

Wilko, galloping at Hollywood Park on Saturday, worked five furlongs in 59.60 seconds Sunday.

INGLEWOOD, Calif. - David Flores, who suffered a dislocated elbow in a three-horse spill on Saturday, will miss approximately six weeks and will not travel to Japan for a two-month riding engagement next month.

The injury will prevent Flores from riding two top mounts on Saturday - Lundy's Liability in the $1 million Santa Anita Handicap and Singletary in the $300,000 Frank Kilroe Mile.

Alex Solis has been named to ride Singletary in the Grade 1 Kilroe Mile, run on turf.

Flores underwent surgery over the weekend to have bone spurs removed from his left elbow, according to his agent, Scotty McClellan. He was one of three riders who were hospitalized.

Jockey Alex Bisono, who was treated for muscle soreness and bruises, may return to riding on Thursday, according to his agent, Vic Lipton. Jockey Julio Garcia escaped injury. Garcia's only mount on Sunday was scratched; he is not booked to ride on Wednesday.

The incident occurred in Saturday's eighth race, a six-furlong race for $20,000 claimers.

Approaching the turn, Glen Canyon, ridden by Garcia, broke down while running in sixth place, resulting in a chain reaction that caused Bornwithit (Flores) and Indiaman (Bisono) to fall.

Garcia and Flores rose on their own power, but were helped into ambulances. Bisono remained on the track and was put on a stretcher before being placed in an ambulance.

Two horses were euthanized - Glen Canyon suffered a compound fracture of his left cannon bone, and Indiaman suffered a neck injury. Bornwithit did not appear to be injured.

Singletary heads for first start since BC Mile

In the Kilroe, Singletary will be making his first start since winning the Breeders' Cup Mile at Lone Star Park in October. He worked seven furlongs in 1:25.40 at Hollywood Park on Saturday.

Solis has never ridden Singletary, who has won 6 of 16 starts and $1,439,732 for the Little Red Feather partnership.

"I've always been a Solis fan," trainer Don Chatlos said. "I've just never had the horses to use him on a consistent basis. He stays consistent all the time.

"I've always been of the impression that the stronger the rider, the better for this horse. You don't have to hit him. You've got to muscle him home."

The Kilroe has an outstanding list of probable starters. Singletary was assigned top weight of 121 pounds and will face Buckland Manor, Fitz Flag, Just Wonder, Laura's Lucky Boy, Leroidesanimaux, Meteor Storm, and Sweet Return. All are stakes winners.

A to the Z, the winner of the California Cup Mile, is passing the race in favor of the $500,000 Mervin Muniz Jr. Handicap at Fair Grounds on March 19, trainer Paula Capestro said.

Saturday's card marks the 3-year-old debut of Declan's Moon, the champion 2-year-old male of 2004, in the $200,000 Santa Catalina Stakes at 1 1/16 miles.

Declan's Moon will be heavily favored in a short field that is expected to include Going Wild, Snack, and Spanish Chestnut. All of those probable starters are stakes winners.

Two-day gap in milkshake testing

Testing for excessive carbon dioxide levels, or milkshakes, was not conducted at Santa Anita on Feb. 21 and 23 and was done on a limited basis on Feb. 24 because of a lack of available staff, an official said over the weekend.

Full testing of all entrants resumed Friday and continued over the weekend.

According to Dr. Rick Arthur, the spokesman for a consortium of organizations conducting the tests, one of the veterinarians involved with the testing was traveling during those days and was not replaced.

"It was an oversight," Arthur said. "It was nothing intentional. A replacement was not put in there."

The consortium that is conducting and financing the tests consists of Santa Anita, the Thoroughbred Owners of California, and the California Thoroughbred Trainers.

The testing has been conducted since the meeting began on Dec. 26, and has revealed five positive tests for excessive levels of carbon dioxide. The four trainers cited for positives - Vladimir Cerin, Julio Canani, Adam Kitchingman, and Jeff Mullins - have been penalized by having their horses placed in a detention barn 24 hours before starting, for a span of 30 days.

Horses trained by Mullins and Canani will be detained until March 10, Cerin through March 14, and Kitchingman through March 25. Following the expiration of those penalties, all starters from those trainers will undergo additional surveillance for 15 days.

Canani trains Sweet Catomine, the champion 2-year-old filly of 2004. She is scheduled to start in the Santa Anita Oaks on March 13, and will undergo additional surveillance at Canani's barn in the buildup to that race.

Arthur described the additional surveillance as "backside security people spending extra time in those barns at various times of the day."

Arthur said that 2,707 horses have been tested at the meeting.

"When you consider the change that is taking place in a relatively short period of time, when previously there was really lax supervision by the CHRB, and the racetrack has stepped up and taken an active role, I think it's a positive move," he said.

Pico Central to go to Dubai off works alone

The major stakes winners Pico Central, Roman Ruler, and Wilko worked over the weekend, preparing for comebacks.

Pico Central, a four-time stakes winner last year, breezed five furlongs in 1:03.60 at Hollywood Park on Saturday and remains on schedule for the $2 million Golden Shaheen Sprint in Dubai on March 26.

Trained by Paulo Lobo for Gary Tanaka, Pico Central was expected to start in Saturday's San Carlos Handicap, but he bruised a foot in mid-February. Unraced since finishing third in the Grade 1 Cigar Mile at Aqueduct last November, Pico Central will not have a prep race before Dubai, Lobo said.

"He worked very well," Lobo said Sunday. "The most important thing is he came back okay today."

Lobo said Pico Central is scheduled to be shipped on March 12.

Wilko, the winner of the Breeders' Cup Juvenile at Lone Star Park in October, is moving closer to his 3-year-old debut.

Sunday, Wilko breezed five furlongs in 59.60 seconds at Hollywood Park. He is scheduled to start in the $250,000 San Felipe Stakes at 1 1/16 miles on March 19. Wilko was supposed to return in the Santa Catalina but lost too much time because of wet weather, trainer Craig Dollase said.

"We are on target for the 19th," Dollase said. "We don't need any more interruptions. We got a good breeze into the horse. I feel he got something good out of this work."

Roman Ruler, a two-time stakes winner last year, worked six furlongs from the gate in 1:12.40 at Santa Anita on Sunday. He missed the San Vicente Stakes because of a quarter crack, and is a candidate for the $150,000 Gotham Stakes over a mile at Aqueduct on March 19.
