Dr. Kathy no longshot here


OZONE PARK, N.Y. - Dr. Kathy's odds were 45-1 when she finished third against two good fillies, Ashado and La Reina, in the Grade 2 Demoiselle on Nov. 29. But in Sunday's $60,000-added Open Mind Stakes at Aqueduct, Dr. Kathy's odds will dip significantly.

Dr. Kathy is the likely favorite among eight 2-year-old fillies entered in the mile and 70-yard Open Mind. Fond was cross-entered in a Saturday allowance race.

In the Demoiselle, where Ashado beat La Reina by a nose, Dr. Kathy was third, beaten a half-length. Before winning the Demoiselle, Ashado was second in the Breeders' Cup Juvenile Fillies behind the likely 2-year-old filly champion, Halfbridled.

The 1 1/8-mile Demoiselle was Dr. Kathy's first start on the dirt around two turns. In October, Dr. Kathy, who is trained by Richard Dutrow Jr., won the two-turn Salem County Stakes on the grass at The Meadowlands.

Aaron Gryder rides Dr. Kathy, who drew post 3 and should get an ideal stalking trip behind the pacesetters.

Leedle Dee controlled the pace in the slowly run East View Stakes to win by 5 1/4 lengths Dec. 10. A New York-bred, Leedle Dee should expect pace pressure from Dreamadreamforme, who won at Philadelphia Park, and Fond, if she starts.

Taittinger Rose, Shamoiselle, Royal Magician, and Pro Occident also were entered.

Pony rider hurt in accident

Hannah Blumenthal, a pony rider at Belmont Park, suffered a severe head injury in a riding accident Friday.

Blumenthal, 52, was unconscious and bleeding from her nose after she fell from her pony on Belmont's pony track at 8:05 a.m. She was transported by ambulance to Winthrop Hospital in Mineola.

Friday afternoon, Winthrop officials said Blumenthal was in critical condition in the neurosurgery intensive care unit after undergoing surgery earlier in the day.

Blumenthal, who worked as a freelancer for many years at New York tracks, was ponying a horse for trainer Colum O'Brien. Eyewitnesses said the horse got away from Blumenthal and wheeled, causing Blumenthal to lose her stirrups. The pony was galloping at full speed when he made a sharp turn at the gap, and Blumenthal was thrown. Her head struck the rail as she fell to the ground. Blumenthal was wearing a helmet.

Detectives at the 5th precinct of the Elmont Police Department were investigating the accident.

Samyn's comeback set

Jockey Jean-Luc Samyn, who broke his right leg in a spill at Saratoga on Aug. 20, hopes to begin riding races in about three weeks at the Gulfstream Park meet, which opens Jan. 3. Samyn has been jogging horses at Belmont since Dec. 10 and galloped his first horse recently.

Samyn, 47, believes Florida's balmy weather will be easier on his body than the cold weather during winters in New York.

"I thought the cold weather would make it much more difficult and I would be more comfortable in Florida," said Samyn, who will leave for Florida later this week. "I think Florida is the right move for me."

Samyn will get fit by getting on horses in the morning at Gulfstream for, among others, trainer Allen Jerkens, for whom he rides regularly in the afternoon.

A plate and 14 screws were needed to repair the fracture in Samyn's femur bone.

* Friday's card began and ended with the name Julia. Quiet Julia ($6.80) won the opener and Sensational Julia ($12.40) won the finale.
