Nayarra, the only transnational shipper in the race, captured the Group 1 Premio Gran Criterium by a half-length on Sunday at San Siro in Italy.

Nayarra, ridden to victory by Martin Dwyer and trained by Mick Channon, came into the Gran Criterium an eight-race maiden who had been mildly competitive with Group 3 types in England, but emerged victorious in a race worth a almost $400,000. He became the eighth consecutive England-based winner of Italy’s most important race for 2-year-olds.

Parish Hall, who had been second in two group stakes in Ireland during the summer, pulled a 20-1 upset in Saturday’s Group 1 Dewhurst Stakes at Newmarket, England, beating favored Power by a half-length.

Black Caviar, Australia’s reigning Horse of the Year, extended her unbeaten streak to 14 races in Saturday’s Group 2 Schillaci Stakes at Caulfield, Australia. Black Caviar’s streak now equals the longest winning streak of the mighty Phar Lap, who won 14 straight in 1930-31.

The Group 1 Premio Gran Criterium, Italy’s most important race for 2-year-olds, often attracts a good horse from an internationally known stable. Last year, for instance, the Godolphin-owned Biondetti won the Gran Criterium and went on to finish a respectable fourth behind Uncle Mo in the Breeders’ Cup Juvenile. But for whatever reason, this year’s edition of the race, scheduled for Sunday at San Siro, failed to attract any serious ship-ins, and drew a field of only seven.

A new $1 million race has been added to the Dubai World Cup program at Meydan Racecourse next March, but it is unlikely to figure prominently among American invaders.

Meydan officials announced on Thursday that the $1 million Dubai Gold Cup over about two miles on turf will be added to the World Cup card on March 31. The race will be part of a nine-race program, which will feature eight races for Thoroughbreds and one for Arabians.

With the new race, prize money on the Dubai World Cup program will be $27.25 million.

Black Caviar, unbeaten in 13 starts and Australia’s reigning Horse of the Year, will be an overwhelming favorite to win her first start since May in the Group 2 Schillaci Stakes at Caulfield, Australia, on Saturday.

Black Caviar is the star attraction on a nine-race program that features three Group 1 races, including the Caulfield Guineas. Trained by Peter Moody, Black Caviar has been in serious training for a month in preparation for the Australian season.

ARC DE TRIOMPHE WEEKEND: More recaps and video replays from Longchamp »

By getting so good, so fast, the 3-year-old German filly Danedream might have run herself out of a start in the 2011 Breeders’ Cup.

The 4-year-old filly Curran Chan won her fourth consecutive race, and first Group 1, beating males in the $2.4 million Sprinters Stakes at Nakayama Racecourse in Japan on Sunday.

Rocket Man, the winner of the $2 million Golden Shaheen for sprinters in Dubai in March, could only finish fourth as the heavy favorite.

Nahrain remained unbeaten after four races, and earned a fees-paid berth to the Breeders’ Cup Filly and Mare Turf next month, with a nose victory in the Group 1 Prix de l’Opera at Longchamp Racecourse in Paris on Sunday.

Nahrain outfinished Announce to give trainer Roger Varian his first career Group 1 win. Ridden by Frankie Dettori, Nahrain, 3, was always near the front in the race over about 1 1/4 miles for fillies and mares. She took the lead in the final furlong and was fully extended to hold off Announce, the 2-1 favorite.
