The Tuesday racecard at Delaware Park has been cancelled on the orders of the state racing commission's supervisory veterinarian, who cited expected high temperatures as posing a danger to horses and riders.

Dr. John Peters, the state's highest veterinary authority, made the recommendation on Monday to the Delaware Department of Agriculture, which includes the Delaware Thoroughbred Racing Commission. John Wayne, the administrator of racing for the commission, said that Delaware Park management supported the decision.

The slots-rich Zia Park in Hobbs, N.M., will put on one of racing's most lucrative programs for statebreds on Nov. 11, when it offers more than $1.6 million for the New Mexico Cup. The program comprises 11 stakes for Thoroughbreds and Quarter Horses bred in New Mexico. It is the highlight of the fall mixed meet that will open on Sept. 22.

DEL MAR, Calif.-Apparently, it will take more than a case of crafty race-riding from a rival jockey to end Nashoba’s Key’s undefeated streak.

In Sunday’s $300,000 Clement Hirsch Handicap at Del Mar, Nashoba’s Key overcame traffic in a field of four to win her sixth consecutive race, four of them stakes.

The victory emphasized her status as the leading older female in the West. To win the Grade 2 Hirsch over 1 1/16 miles, Nashoba’s Key needed a patient ride from jockey Joe Talamo, 17.

OCEANPORT, N.J. - Any Given Saturday rallied for an emphatic 4 1/2-length victory Sunday over Hard Spun and Preakness winner Curlin in the $1 million Haskell Invitational at Monmouth Park.

Garrett Gomez saluted the crowd of 43,106 with a jubilant whip pump as Any Given Saturday ($5.60) earned his first Grade 1 victory and raised his profile within the 3-year-old division.

The decisive margin and the quality of the field was a powerful statement by an emerging star.

ETOBICOKE, Ontario - Marchfield ($9.30) rallied from far back under Patrick Husbands to capture the 117th running of the $501,600 Breeders' Stakes, the third leg of the Canadian Triple Crown at Woodbine on Sunday.

It was the first stakes victory and turf debut for Marchfield, a nicely bred A.P. Indy colt with a quality turf pedigree. Trained by Mark Casse for Melnyk Racing Stable, he earned $300,000, which brought his career earnings to $463,753.

SARATOGA SPRINGS, N.Y. - When Silver Tree has lost at Saratoga, it has taken a championship caliber horse to beat him. There were no such animals in Sunday’s Grade 2, $150,000 Fourstardave Handicap.

Silver Tree, under Kent Desormeaux, exploded in the final sixteenth of a mile to win the Fourstardave by three-quarters of a length over Drum Major. It was one length back to Host in third.

Woodlander finished fourth and was followed by Giant Basil, Brilliant, the 9-5 favorite who stopped badly after taking the lead in mid-stretch, and Fishy Advice.

DEL MAR, Calif. - Jockey Rafael Bejarano had Saturday's $400,000 John Mabee Handicap at Del Mar figured out from the start.

Bejarano guided his mount, Precious Kitten, into a stalking position behind Dancing Edie in the first few strides of the Grade 1 turf race, a strategy that led to an ideal trip. Precious Kitten, who was expected to be near the front, rallied three wide on the final turn to take the lead in the stretch before pulling away to score the most prestigious victory of her 15-race career.

SANTA ROSA, Calif. - Relaxing nicely on the lead, defending champion Now Victory ($3.40) had no trouble repelling a brief challenge by Saratoga's Magic at the quarter pole to score an easy victory in the $50,930 Joseph T. Grace Handicap on Saturday at the Sonoma County Fairgrounds.

Now Victory had an open lead on Saratoga's Magic, taking command as the field of six raced to the first turn. He relaxed nicely under Frank Alvarado and still hadn’t been asked when Saratoga’s Magic crept within a half-length at the quarter pole.

HENDERSON, Ky. - John Witte ran into the winner's circle trembling. "This is my greatest day in racing," said Witte. "Here we are, in my old Kentucky home. This is the best."

Witte had just watched a horse he owns in partnership, Unplugged, get up in the final stride to win one of the seven Claiming Crown races run amid sweltering conditions at Ellis Park. For the first time in its nine-year history, the Claiming Crown was run in Kentucky, and Witte, a Delaware resident who is a partner in J.D. Racing Stable, was ecstatic to have made the trip.

Stormello was scratched from Sunday's $1 million Haskell Invitational after developing colic.

The winner of the Grade 1 Hollywood Futurity last December, Stormello arrived at Monmouth Park from California late Friday afternoon and showed signs of distress later that evening.

He was vanned to the Midlantic Equine Clinic in Ringoes, N.J., for treatment.
