Agent: P. Val still in hospital

Point Determined will make his turf debut in Sunday's Del Mar Derby.

DEL MAR, Calif. - Jockey Patrick Valenzuela, who has not ridden since July 16, remains hospitalized in the Los Angeles area for undisclosed reasons, according to his agent, Tom Knust.

His prolonged absence has led California Horse Racing Board officials to seek opinions from the state attorney general's office as to whether Valenzuela has violated terms of his provisional jockey's license, according to CHRB executive director Ingrid Fermin.

"I asked for a review of the contract and I haven't gotten an opinion yet," Fermin said Thursday.

Part of the provisional agreement is that Valenzuela be available for drug testing. He has not been tested since he entered the hospital in late July. Valenzuela was tested at his home on July 19 and 20, and was admitted to the hospital on July 22, Knust said.

Valenzuela has ridden under a provisional license since the late 1990's.

Neil Papiano, Valenzuela's attorney, was not available for comment on Thursday.

Knust said it was unclear how long Valenzuela would remain hospitalized.

"I don't know, that's the question now," Knust said. "It will be until the doctor releases him. He's concentrating on what he needs to concentrate on."

He declined to elaborate on the reasons for Valenzuela's hospitalization. Asked if Valenzuela would ride this year, Knust said, "Hopefully, yes."

Valenzuela has not ridden since the final day of the Hollywood Park spring-summer meeting. When he failed to appear for the opening day of the Del Mar meeting on July 19, Knust said that Valenzuela was suffering from a back injury. At the time, he said Valenzuela would be out for six to eight weeks.

Valenzuela, 43, has a history of substance abuse problems. He missed the second half of 2004 because of a suspension related to an absence early that year. He returned to riding in early 2005.

Prime Ruler drills for futurity

Prime Ruler, a maiden winner here on Aug. 5, worked a half-mile in 47.40 seconds on Thursday, preparing for his stakes debut in Wednesday's $250,000 Del Mar Futurity.

The Grade 2 Futurity is the closing-day feature of the meeting.

Trainer Christopher Paasch timed Prime Ruler in 47.60 seconds, including a first furlong in 12.40 and the last three furlongs in 35.20. "I didn't want him to go in 46," Paasch said.

Paasch had intended to work Prime Ruler five furlongs, but shortened the distance of the workout when he expressed concern that the racetrack was deep.

Prime Ruler is one of five probable starters in the seven-furlong Futurity, a field that lacks a stakes winner. The other expected starters are Great Hunter, Horse Greeley, Hot Flame, and Stormello.

E Z Warrior, the winner of the Hollywood Juvenile Stakes, and the Paasch-trained Principle Secret, who won the Best Pal Stakes, are being prepared for stakes in October.

Prenuptial upsets Generous Portion

Prenuptial ($57.20) was the longest shot in the field when she pulled an upset in Wednesday's $108,400 Generous Portion Stakes. The person most surprised by the victory may have been trainer Ben Cecil.

He admitted after the race that Prenuptial had not trained impressively since a sixth-place finish in the CTBA Stakes on July 21.

"She had a couple of pretty terrible works," Cecil said. "There was nowhere else to run, so we tried a new strategy. We had nothing to lose. I couldn't say I was overly confident going in."

His opinion changed as the race developed. Ridden by Martin Pedroza, Prenuptial rallied from last to win by a head over Swiss Rose. Another head back was Sharoana, who set an early pace of 21.54 and 45.15 seconds.

"The pace helped us," Cecil said. "I said to Martin, 'Sit on her until the three-eighths pole and make one move.' It set up well."

Ces't Mark, the 9-5 favorite, finished fourth, failing to replicate the form of her win in the CTBA Stakes.

Prenuptial ran six furlongs in a pokey 1:12.56, winning for the second time in four starts for owners David and Paula Mueller.

Point Determined points for grass

Point Determined, the winner of the Grade 3 Affirmed Handicap at Hollywood Park in June, will make his turf debut in Sunday's $400,000 .

Trained by Bob Baffert for Beverly Lewis, Point Determined is making his first start since finishing second in the Grade 2 Swaps Breeders' Cup Stakes at Hollywood Park on July 8.

Point Determined is one of five stakes winners entered in the Grade 2 Del Mar Derby, which is run at 1 1/8 miles on turf. He is joined by Lightning Hit, Obrigado, Porto Santo, and Union Avenue.

Valdivia to ride Arravale in Canada

Jockey Jose Valdivia Jr. will ride Del Mar Oaks winner Arravale in the $300,000 Canadian Stakes at Woodbine on Sept. 17, according to his agent, Michelle Barsotti.

The Canadian Stakes is run at 1 1/8 miles on turf. Valdivia rode Arravale for the first time in the Grade 1 Del Mar Oaks on Aug. 19. Arravale is based at Woodbine with trainer Mac Benson.
